The invention is further described with reference to the following embodiments, which are provided for illustration only and are not intended to limit the scope of the invention.
The invention relates to operation-based conversion hypertext markup language (HTML) real-time collaborative editing method, wherein an HTML document is defined according to a label pair and comprises pure text data and attribute data of modified text.
As shown in fig. 1, the method comprises the steps of:
step 1: performing layered modeling on the HTML document according to attribute data of the modified text to generate a tree-shaped hierarchical structure model; the hierarchical modeling further comprises the steps of:
the method comprises the steps of 1.1, determining a root node of an HTML document according to attribute data of a modified text in the HTML document, wherein the attribute data of the modified text in the HTML document comprises data such as font size, color and format of the document, the tags are nested in a layering mode according to different tag pair descriptions, as shown in figure 2, documents are subjected to a layering schematic diagram, and the root node of the HTML document is determined to be a document (document) according to different format attributes (italic) in the HTML document.
Step 1.2: dividing a root node document (document) downwards layer by layer, and determining child nodes of each layer; the root node document (document) is divided into three levels of children, paragraph 1(paragraph1), paragraph 2(paragraph2), and paragraph 3(paragraph 3).
Step 1.3: continuously dividing sub-nodes paragraph1, paragraph2 and paragraph3 of each layer according to attribute data of a modified text into a sentence1 (sensor 1) and a sentence2 (sensor 2), as shown in fig. 3, a schematic diagram of continuously dividing sensor 1 carrying format attributes, namely "talkischiap, showme the code", into three layers of new sub-nodes which are respectively a text (text) type, a phrase (phrase) type and a text (text) type, and continuously dividing the sub-nodes of the phrase type into two text types according to the format attributes in an HTML document, performing layer-by-layer division until the sub-nodes cannot be divided, and generating a tree hierarchical structure model;
the attribute data of the root node can influence the sub-nodes of each layer divided downwards layer by layer, so that the sub-nodes of each layer are added with the attribute data of each layer, the root node of each layer is continuously divided according to the attribute data of each layer until the attribute data of each layer of the root node of each layer cannot be continuously divided, the format attribute in the text type cannot be continuously divided, and the layer-by-layer division is stopped; the root node of each layer includes plain text data, attribute data of the modified text, and attribute data of each layer.
The child node (child) attribute represents the attribute of the child node of each layer pointed by the root node, the text attribute represents the plain text data in the HTML document, the bold (bold) attribute represents the bold of the text format in the HTML document and has two attribute values of 'yes' and 'no', and the tilt (italic) attribute represents the tilt of the text format in the HTML document and has two attribute values of 'yes' and 'no'.
Step 2: determining the address of an operation node of the HTML document according to the tree hierarchical structure model; determining the operational node further comprises the steps of:
step 2.1: naming the root node, and anonymizing the child nodes of each layer;
step 2.2: establishing a path index vector i between the root node R and each layer of child nodes by taking the root node as a reference point RkK is the number of anonymous nodes, and k is 0,1,2, 3.; the number m of the path index vectors between the root node R and the child nodes of each layer meets the following requirements:
m＝|ik|；
that is, the number m of the path index vectors is | [1,3,2] | ═ 3;
step 2.3: the root node R and the path index vector ikPerforming combination processing to generate an address N of each layer of child nodes, namely the address N of the operation node; the address of the kth operating node is N [ k ]]And satisfy
N[k]＝(R,[i0,i1,…])。
And step 3: and immediately executing local operation according to the address of the operation node to generate local operation information, and mapping and storing the local operation information in a user side operation cache (HB).
The local operation comprises a specific operation and an operation address; the specific operations include an insert operation, a delete operation, and a change operation.
The inserting operation is insert (N, k, N), and is to insert the node N into the HTML document at the kth child node position of the root node with the address of N; if the inserted address N has an operation node k, the node N replaces the original position of the operation node k to become a kth operation node, and the original operation node k becomes a brother node of the operation node N; if the inserted address N has no operation node, directly inserting the node N at the position of the kth operation node.
The delete operation is delete (N, k, N), which deletes the node N at the kth child node position of the root node with address N.
Changing the operation into change (N, l, f (v)), changing the attribute data l of the modified text of the root node of the address N executed by the change operation into f (v), wherein f is a conversion function, and inputting an old value and returning a new value; before the operation is executed, if the value of attribute data l of the modified text in the HTML document is a character, f (v) can be a font format, a size and the like; if the attribute data l of the modified text in the HTML document is in a font format, f (v) may be a song style, a bold style, or the like.
And 4, step 4: the plurality of user sides operate cooperatively, the local user side receives the local operation information of other user sides as the remote operation information of the local user side, and sends the local operation information of the local user side to the other user sides as the remote operation information of the other user sides.
And 5: performing dependence check on the local operation information and the remote operation information received by the local user side; if the local operation information and the remote operation information have a dependency relationship, operation conversion is not needed; and if the local operation information and the remote operation information do not have a dependency relationship, performing operation conversion to complete real-time collaborative editing.
Before the local operation information and the remote operation information are subjected to operation conversion, address precedence relation comparison is required to be carried out on the remote operation information and the local operation information. Comparative remote operation OaAddress N of operating nodeaAnd local operation ObAddress N of operating nodeb：
compare(Na,Nb)＝PREFIX(k)；
If the root nodes of the two are the same Ra＝Rb，0<|Nb|<(|NaIf 1), then return PREFIX (k), i.e. local operation ObAddress N of operating nodebIs a remote operation OaAddress N of operating nodeaFront k-bit prefix of, remote operation OaAddress N of operating nodeaFirst k elements of and local operation ObAddress N of operating nodebThe same; if the root nodes of the two are different from each othera≠RbIf yes, returning to differential; if the addresses of the two are the same in sequence, Na＝NbIf yes, returning to same; if the addresses of the two are different in sequence, Na≠NbThen differential is returned.
