It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The data acquisition method of the webpage elements is applied to the application environment shown in fig. 1. The server 110 is used for implementing a data acquisition method of a web page element of the present application. Among them, the server 110 may be a computer device supporting an RPA (Robotic Process Automation) designer. The server 110 is communicatively coupled to the terminal device 120. The terminal device 120 is a user terminal device used by a consumer of web page data information. The terminal device 120 may present web pages of different web page structures. When the terminal device 120 displays the first target webpage 121, the server 110 obtains first webpage element path information in the first target webpage 121. When a user triggers at least two web page elements of the same type of the first target web page 121, for example, triggers two titles of the same title type in the first target web page 121, the server 110 obtains path information of the triggered first web page element, further obtains first similar path information with a similar path structure according to the path information of the first web page element, determines a plurality of first target elements in the first target web page according to the first similar path information and the path information of the first web page element, and finally obtains web page data of the plurality of first target elements. Further, the server 110 is also communicatively connected to the terminal device 130. The terminal device 130 is a terminal device used by a developer who performs data processing on web page data information. The developer uses the terminal device 130 to perform corresponding operations on the server 110. The web page data of the plurality of first target elements obtained by the server 110 may be displayed in the display interface 131 of the terminal device 130 for the developer to preview. The server 110 may be implemented as a server cluster composed of a plurality of servers, and the terminal device 120 may be a notebook, a desktop, other mobile devices, and the like.
In one embodiment, as shown in fig. 2, a data obtaining method for a web page element is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
s101, acquiring first webpage element path information of a first target webpage.
In this embodiment, when the terminal device opens the first target webpage, the server obtains first webpage element path information of the first target webpage in the terminal device. The obtaining manner may be that the server parses a DOM (Document Object Model) tree structure of the first target web page, and obtains the first web page element path information of the first target web page according to the DOM tree structure of the first target web page. The first web page element path information is used to identify path information for all web page elements in the first target web page.
In one embodiment, step S101 includes: and traversing the DOM tree structure of the first target webpage, and generating first webpage element path information according to the traversal result.
In this embodiment, the server generates the first web page element path information of the first target web page by traversing the DOM tree structure of the first target web page. Specifically, when the terminal respectively clicks a target element a and a target element B in a first target webpage through a mouse, the server traverses up the DOM tree of the entire first target webpage layer by layer to generate first webpage element path information that can uniquely identify the first target webpage. For example, the first webpage element path information is html- > body- > div- > table.
S103, when at least two webpage elements of the same type in the first target webpage are triggered, acquiring the path information of the triggered first webpage element.
In this embodiment, when at least two web page elements of the same type in the first target web page are triggered, the server acquires path information of the triggered first web page element. Here, the at least two web page elements of the same type may be triggered sequentially, or triggered simultaneously. In this embodiment, the server only needs to detect that at least two web page elements of the same type are in the triggered state. Wherein the same type of web page elements refer to web page elements identified as the same type in the first target web page. The number of the triggered first webpage elements is multiple. The web page element may be triggered by manually triggering the web page element in the first target web page in the terminal device. Or after the server reads the first target webpage to the server, the research and development personnel trigger webpage elements in the first target webpage in the server through the terminal device in communication connection with the server. In addition, the server can directly read the path information of all the webpage elements in the first target webpage from the terminal equipment displaying the first target webpage, and when the first webpage element is triggered, the server can directly read the path information of the first webpage element.
S105, acquiring first similar path information with similar path structure according to the path information of the first webpage element.
In this embodiment, the number of the triggered first web page elements is multiple, and the server obtains the first similar path information according to the path information of the triggered first web page elements. The first similar path information comprises path information with similar path structures in the path information of the plurality of first webpage elements. For example, the path information of the first web page element a is: html- > body- > div- > table- > tr [1], and the path information of the first webpage element B is: html- > body- > div- > table- > tr [2 ]. At this time, the first similar path information includes html- > body- > div- > table- > tr.
S107, determining a plurality of first target elements in the first target webpage according to the first similar path information and the first webpage element path information, and acquiring webpage data of the plurality of first target elements.
In this embodiment, the server determines a plurality of first target elements in the first target webpage according to the first similar path information and the first webpage element path information. The determining method may be that all path information matched with the first similar path information is acquired from the first webpage element path information, and then the webpage elements corresponding to all the matched path information are used as the first target element. For example, the first affinity path information includes html- > body- > div- > table- > tr. At this time, the first webpage element path information acquisition path structure prefix includes webpage elements corresponding to all path information of html- > body- > div- > table- > tr as the first target element. And finally, acquiring the webpage data of all the first target elements, thereby realizing the batch acquisition of the webpage data of all the elements with similar paths in the first target webpage.
In a specific implementation process, the first target webpage is a webpage list. And clicking the target element A under the webpage list and the target element B under the webpage list by using a mouse. The target element A and the target element B are the triggered first webpage elements of the same type. The server traverses the DOM tree of the whole webpage list layer by layer upwards, and the first element path information which can uniquely identify the webpage list is generated as follows: html- > body- > div- > table, and the path information of the target element a is: html- > body- > div- > table- > tr [1], and the path information of the target element B is: (html- > body- > div- > table- > tr [2 ]). Therefore, the obtained first similar path information is: html- > body- > div- > table- > tr. According to the first element path information and the first similar path information of the web page list, all elements of similar paths under the web page list, that is, the plurality of first target elements, can be retrieved. And finally, acquiring the webpage data of a plurality of first target elements, thereby realizing the batch acquisition of the webpage data of the webpage elements with similar paths in the webpage list.
The data acquisition method of the webpage elements acquires first webpage element path information of a first target webpage. And when at least two webpage elements of the same type in the first target webpage are triggered, acquiring the path information of the triggered first webpage element, and acquiring first similar path information with similar path structures according to the path information of the first webpage element. Further, a plurality of first target elements in the first target webpage are determined according to the first similar path information and the first webpage element path information, and finally webpage data of the plurality of first target elements are obtained. Therefore, the method can acquire the webpage data of the elements of the same type under the webpage in batch according to the webpage element path information of the webpage and the path information of the elements of the same type in the webpage aiming at the webpage structures of different webpages. In addition, the method obtains the webpage data in batch by analyzing the webpage element path information of the webpage, and is suitable for obtaining the webpage data with any webpage structure.
In one embodiment, before step S103, the method further includes the steps of: acquiring a boundary value of the first webpage element according to the coordinate value of the first webpage element in the first target webpage; a mask layer for the first web page element is generated based on the boundary value. At this time, step S103 includes: and acquiring the path information of the triggered first webpage element according to the mask layer.
In this embodiment, the positions of the web page elements in the first target web page are identified by means of a coordinate system. When a first webpage element in the first target webpage is triggered, a coordinate value of the first webpage element in the first target webpage is obtained, and a boundary value of the first webpage element is obtained according to the coordinate value. Further, a mask layer for the first web page element is generated according to the boundary value, so that the link jump does not occur when the content containing the jump link attribute in the first web page element is triggered. Further, the server acquires the path information of the triggered first webpage element according to the mask layer. Specifically, when the server identifies the mask layer of the first web page element, the server obtains the path information of the first web page element. If the first webpage element contains the skippable link attribute content, the server identifies the mask layer of the first webpage element, and at the moment, the path information of the first webpage element can be acquired when the first webpage element is triggered, so that the phenomenon that the path information of the first webpage element cannot be acquired due to skipping when the first webpage element is triggered is avoided.
In a specific implementation process, when a mouse slides over a certain webpage element of a first target webpage, namely a triggered first webpage element, a boundary value of a rectangular frame of the first webpage element is obtained according to an (x, y) coordinate value of the first webpage element on the current first target webpage (the coordinate of the first target webpage is a two-dimensional coordinate represented by an x coordinate system and a y coordinate system). The mask layer for the first web page element is generated by the boundary value, and ensures that the target content with href (uniform resource locator (URL) for specifying the hyperlink target) attribute does not click to jump when the mouse slides over the first web page element to capture the target content by drawing a frame for the first web page element.
In one embodiment, as shown in fig. 3, after step S107, the method further includes the steps of:
s109, page turning information in the first target webpage is obtained.
And S111, acquiring a second target webpage according to the page turning information.
S113, second webpage element path information of the second target webpage is obtained.
S115, when at least two web page elements of the same type in the second target web page are triggered, the path information of the triggered second web page element is obtained.
And S117, acquiring second similar path information with similar path structure according to the triggered path information of the second webpage element.
S119, determining a plurality of second target elements in the second target webpage according to the second similar path information and the second webpage element path information, and acquiring webpage data of the plurality of second target elements.
In this embodiment, the first target web page includes page turning information. The page turning information is used to instruct the web page to jump from the current web page to another web page. Wherein, the page turning information may be jump link indication information. The server acquires a second target webpage according to the page turning information in the first target webpage, and further executes operations similar to the steps S101 to S107 for the second target webpage to acquire webpage data of a target element in the second target webpage. Specifically, when at least two web page elements of the same type in the second target web page are triggered, the server acquires the path information of the triggered second web page element, and acquires second similar path information with similar path structures according to the path information of the triggered second web page element. And finally, determining a plurality of second target elements in the second target webpage according to the second similar path information and the second webpage element path information, and acquiring webpage data of the plurality of second target elements.
For example, web page data of a target element in a first target web page is obtained through one or more entry addresses. As the article list address of the first web page: https:// www.cnblogs.com/# p1, web page data for a target element in a first web page is obtained. Specifically, the capturing of the web page data of the article list of the first web page is completed according to the operations of step S101 to step S107. And entering the next level webpage, namely the second target webpage according to the page turning information of the entry webpage, namely the page turning information of the first webpage, such as the link point https:// www.cnblogs.com/# p 2. The operations of step S109 to step S119 are performed in the second target web page to capture the web page data of the target element in the second target web page. And circulating infinitely until the page turning information is executed.
In one embodiment, step S107 includes: and acquiring the same-level elements and parent-level elements of the triggered first webpage elements of the same type from the first target webpage according to the first similar path information and the first webpage element path information, and respectively taking the triggered first webpage elements of the same type, the same-level elements and the parent-level elements as the first target elements.
In this embodiment, the first similar path information is path information with a similar path structure determined according to the triggered path information of the first web page elements of the same type. The first web page element path information is a set of path information for web page elements of the first target web page. According to the first similar path information and the first webpage element path information, the same-level element and the parent-level element of the triggered first webpage element of the same type can be determined. Specifically, all path information matched with the similar path information is acquired from the first webpage element path information, and the same-level element and the parent-level element of the triggered first webpage element of the same type are acquired from the first target webpage according to the all path information.
In one embodiment, step S107 includes: acquiring configuration information of a first target webpage, wherein the configuration information is used for indicating to extract data of preset parameters in webpage elements of the first target webpage; and acquiring webpage data of a plurality of first target elements according to the configuration information.
In this embodiment, the web page elements of the first target web page include data corresponding to a plurality of parameters. In a specific implementation process, the acquired target element is often an html element, and there is web page data corresponding to attributes such as title attribute information, href attribute information, class attribute information, and the like, so that the finally acquired data can be configured in advance. In this embodiment, the server obtains the web page data of the preset parameter in the plurality of first target elements according to the configuration information of the first target web page.
In one embodiment, the preset parameters include text parameters and/or link parameters. Acquiring webpage data of a plurality of first target elements according to the configuration information, wherein the acquiring comprises the following steps: and acquiring the text data and/or the link data in the plurality of first target elements according to the configuration information, wherein the webpage data comprises the text data and the link data.
In this embodiment, the preset parameters include a text parameter and/or a link parameter. The configuration information is used for indicating webpage data for extracting the text parameter and/or the link parameter in the webpage element of the first target webpage. And the server extracts the text data and/or the link data from the plurality of first target elements according to the indication parameters in the configuration information.
For the data acquisition method of the web page element, a specific implementation scenario is given below to further detail the data acquisition method of the web page element:
a server that implements the data acquisition method for a web page element of the present application is a computer device that supports the operation of an RPA (robotic process Automation) designer. Therefore, the RPA designer can extract different types of webpage data of different webpages by adopting the data acquisition method of the webpage elements. For example, for the commodity list information of the traditional e-commerce website, the related information such as the name or price of the commodity or the description or the evaluation or sales volume can be extracted at one time. Specifically, as shown in fig. 4, the display interface of the RPA designer prompts the developer to select data table 1 in the target web page. As shown in FIG. 5, after the developer opens the target web page, a mouse trigger is used to select the first title. After the RPA designer reads the path information of the first title and the web page data, as shown in fig. 6, a display interface of the RPA designer prompts a developer to select the data table 2 in the target web page. As shown in FIG. 7, the developer continues to open the target web page and uses the mouse to trigger the selection of the second title. The RPA designer reads the path information of the second title and the web page data. The first title and the second title are the triggered first web page elements of the same type of the target web page. The RPA designer determines that the first title and the second title are the same type of web page elements, and can acquire all the web page data of the title class with similar path information in the target web page by executing the data acquisition method of the web page elements. In addition, the RPA designer may also provide configuration options for the developer to select web page data for the corresponding parameters extracted from the web page elements. As shown in fig. 8, the developer can check the parameters to be extracted. Such as text parameters, link parameters. And the RPA designer extracts the webpage data in the target element according to the parameters selected by the research personnel. For example, the configuration chosen by the developer is: the character of the target element is captured, and if the element has the href attribute, the link can be selected and captured.
Further, if the developer wants to crawl more types of web page data, the developer can click to continue the selection. The selection of a web page element in the target web page is illustrated with reference to fig. 9 and 10. For example, the title category of the product is grabbed for the first time, and the grabbing of the price category of the product is required to be continued.
In conclusion, the RPA designer provides a visual webpage data grabbing way and grabbing result screening, and users (such as research and development personnel) can use the webpage data grabbing way and the grabbing result screening more conveniently and efficiently. In addition, compared with the traditional modes of crawling by crawlers and crawling the webpage data by different regular matching aiming at different webpages, the data acquisition method of the webpage elements used by the RPA designer has wider application range, and the circulation of the webpage data becomes efficient and simple in the RPA process.
