S202, searching for the replacement picture of the target picture from the remote server in a remote access mode by using the replacement path corresponding to the target picture.
Specifically, the replacement picture is the target picture that can be loaded in a web page.
Taking picture a as an example, picture a is a picture inserted first in a document to be parsed, a storage address of picture a in a remote server (i.e. a replacement path of picture a) is denoted as Xa, a storage file name of picture a in the remote server is denoted as fig. 1, and by using the replacement path of picture a, the replacement picture of picture a in fig. 1 can be found from the remote server by way of remote access.
S203, displaying the searched replacement picture to the user at the first target vacancy in the display document.
Specifically, the first target slot is a position in the presentation document where the target picture needs to be inserted.
In an exemplary description, still taking the picture a in the above example as an example, because the picture a is located in the first mathematical topic of the document to be parsed, the first target vacancy of the picture a in the display document is also in the first mathematical topic, so that when the document to be parsed is converted into the display document, the replacement picture fig. 1 of the picture a can be found from the remote server by using the replacement path of the picture a in a remote access manner, the picture 1 is inserted into the first mathematical topic of the display document, and the display is performed to the user in a form of a webpage, so that the user can perform online answering in the webpage conveniently.
In a possible implementation, when the determined xml tag is the formula tag, fig. 3 shows a flowchart of a method for processing a formula in a document to be parsed, which is provided by an embodiment of the present application, and as shown in fig. 3, when step S104 is executed, the method further includes S301-S304; specifically, the method comprises the following steps:
s301, aiming at each formula label, obtaining a formula data line marked by the formula label from the document to be analyzed.
Specifically, the formula data line is a permutation and combination of numbers, letters and operation symbols constituting a target formula, and the target formula is a formula in which the formula label is correspondingly marked in the document to be parsed. Exemplary illustrations of the use of the term in a document to be parsed<oMath >The label is used as the formula label, wherein,<oMath >the target formula marked by the label is:
(ii) a Then the formula data behavior corresponding to the target formula can be obtained: y, the value of (= g,
，×，m，+，b。
s302, marking each character included in the formula data line by using a region interval mark, and determining a word segmentation marking result of the formula data line, wherein the region interval mark is a sub-label used for identifying different types of characters in the formula label.
Specifically, as an optional embodiment, a < oMath > tag may be used as the formula tag to mark media elements belonging to a formula in a document to be parsed, where the < oMath > tag includes multiple sub-tags for identifying different types of characters in the formula, for example: the word segmentation method comprises the following steps that a < mi > sub-label used for marking letters, a < mn > sub-label used for marking numbers, a < mo > sub-label used for marking operation symbols and the like are utilized, the sub-labels in the formula labels are used as the region interval labels, each character included in a formula data line can be marked, and the word segmentation marking result of the formula data line is obtained.
Illustrative explanation, the target formula in the above example
By way of example, utilize<oMath >The sub-label in the label marks each character in the formula data line, and can obtain:<mi>y</mi> <mo>=</mo> <mn>1</mn> <mo>-</mo> <mn>2</mn> <mo>×</mo> <mi>m</mi> <mo>+</mo> <mi>b</mi>wherein, in the step (A),</mi>sub-label representation<mi>The sub-label marks the end of the character range,</mo>sub-label representation<mo>The sub-label marks the end of the character range,</mn>sub-label representation<mn>The sub-label marks the end of the character range; thus, the formula data line is divided into independent characters, and the word segmentation marking result of the formula data line is obtained as follows: y, =, 1, -, 2, ×, m, +, b.
And S303, adjusting the display position of each character in the formula data line according to the format of the target formula by using a cascading style sheet to obtain a formula to be imported for displaying in a webpage.
Specifically, taking the sub-tag included in the < oMath > tag (i.e., the sub-tag in the formula tag) as an example of the area interval tag, on the basis of obtaining the segmentation tagging result of the formula data line, in combination with the css style sheet (which may also be called a cascading style sheet), each independent character of the segmentation tagging result can be strictly set, and the display position when the character is displayed in the web page.
Illustratively, taking the character "y" in the above example as an example, according to the < mi > sub-tag for marking the letter, the independent letter y can be recognized, each character marked by the sub-tag is converted into a well-defined tag with a specific class (e.g. class), that is, the character y can be displayed in the web page by using the attribute of the class tag in combination with the css style sheet, and the example of tag conversion is as follows:
< mi y </mi > to < mjx-mi class = "mjx-n" >)
<mjx-c class="mjx-c79">
</mjx-c>
</mjx-mi>
Wherein c79 represents the character y;
thus, the character y can be displayed in the webpage by using the attribute of the class label;
and for the characters "1" - "" 2 "in the above example, because of its format in the target formula:
therefore, the recognized characters "1" - "" 2 "can be shown in the webpage as being combined with the css style sheet through the hierarchical relation contained between the labels
The specific processing example is as follows:
<mjx-table space=4>
< mjx-row size = "s" > < mjx-row > (molecule 1)
< mjx-line > </mjx-line > (horizontal line)
< mjx-row size = "s" > < mjx-row > (denominator 2)
</mjx-table>
Thus, the width of each character is defined through a space instruction, the size of each character displayed in a webpage is defined through a size instruction, the size of the character "1" as a numerator and the size of the character "2" as a denominator displayed in the webpage are defined to be s-type and slightly smaller than other characters, and therefore, the characters "1" - "" 2 "in a formula data line are adjusted according to the format in the target formula, and the characters which are finally used for displaying in the webpage and are to be imported into the formula are obtained
。
S304, displaying the formula to be introduced to the user at a second target vacancy in the display document.
Specifically, the second target slot is a position in the presentation document where the target formula needs to be inserted.
Illustratively, if the target formula is located in the second mathematical topic of the document to be analyzed, the second target vacancy is the second mathematical topic of the display document, the formula to be introduced, which is obtained after the target formula is adjusted in step S303, is introduced into the second mathematical topic of the display document to be displayed to the user, so that the user can conveniently answer the question online in the webpage.
