Embodiment Construction

[0036] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0037] The invention is a hypertext markup language (HTML) real-time collaborative editing method based on operation conversion. HTML documents are defined according to tag pairs, including plain text data and attribute data of modified text.

[0038] Such as figure 1 As shown, the method includes the following steps:

[0039] Step 1: Perform hierarchical modeling on the HTML document according to the attribute data of the modified text to generate a tree-like hierarchical structure model; hierarchical modeling also includes the following steps:

[0040] Step 1.1: Determine the root node of the HTML document according to the attribute data of the modified text in the HTML document. The attribute...

Abstract

The invention discloses an HTML real-time collaborative editing method based on operation conversion. The HTML real-time collaborative editing method comprises the following steps: 1, carrying out hierarchical modeling on an HTML document to generate a tree-shaped hierarchical structure model; 2, determining an address of an operation node according to the tree-shaped hierarchical structure model;3, executing local operation according to the address of the operation node to generate local operation information; 4, performing cooperative operation by a plurality of user sides, and receiving the remote operation information and sending the local operation information to other user sides by the local user side; 5, carrying out dependency check on the local operation information and the remote operation information, wherein if the dependency relationship exists, operation conversion does not need to be carried out; and if the dependency relationship does not exist, performing operation conversion to complete real-time collaborative editing. According to the HTML real-time collaborative editing method, the problems that a traditional linear sequence model is large in document editing limitation and an editing system is complex and inconvenient are solved, and editing of documents containing rich attribute data is achieved, and the use convenience of the real-time collaborative editing system based on operation conversion is guaranteed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an HTML real-time collaborative editing method based on operation conversion. Background technique [0002] The real-time collaborative editing system supports multiple users in different geographical locations to browse and edit a shared document in real time, so that users do not feel the differences in geographical location and barriers of time and space separation, saving users a lot of time and effort. Energy, and ultimately improve the productivity of the user community. [0003] The technology of real-time collaborative text editing operation conversion is very useful. However, the abstract data model used by the main operation conversion editor is a single linear sequence of content data. Such a linear sequence can model plain text, but it cannot model formatted Text modeling, since formatted text must contain metadata about fonts, weights, and colors, etc., i.e. vario...
