Description

TECHNICAL FIELD [0001] The present invention relates to a web document editing apparatus for editing dome objects based on a page change editing command, and a method of operating the web document editing apparatus.

The present invention relates to a technique for editing dome objects based on a page change edit command generated by an edit command input from a user or an electronic document storage server.

2. Description of the Related Art [0002] Recently, various electronic document-related programs have been released to enable electronic documents to be viewed, created, and edited using electronic terminal devices such as computers, smart phones, tablet PCs, and the like.

Examples of such electronic document related programs include a word processor for basic document creation and editing, a data input, an arithmetic operation, a spreadsheet for supporting data management, and presentation programs for assisting presenters.

Conventionally, in order to view, create and edit an electronic document by using an electronic terminal device, a user has to install the above-mentioned electronic document related programs directly in the electronic terminal device, and then operate the electronic document related programs to browse, I had to edit.

However, in recent years, a wireless Internet environment has been established in which a broadband Internet environment is established and a user can access the Internet anytime and anywhere. Thus, by providing an electronic document related service to an electronic terminal device serving as a client terminal through a remote server, A web-based electronic document service that allows an electronic document to be viewed, created, and edited anytime and anywhere without installing a predetermined electronic document-related program in the electronic terminal apparatus is emerging.

Such a web-based electronic document service enables various client terminals to access an electronic document service providing server, browse an electronic document based on a markup language through a browser, and then create and edit the corresponding electronic document And it is mainly utilized in companies and organizations in that various client terminals support simultaneous collaboration on the electronic document in real time.

If a web-based electronic document service can be connected to the Internet without installing a predetermined electronic document creating program on the client terminal, the electronic document service can be browsed, created and edited through a browser installed in the client terminal And thus the mobility of users can be guaranteed, and the number of individual users is also increasing.

Generally, a web-based electronic document service converts an original electronic document into a markup language-based document in order to support a network-connected client terminal to edit an electronic document through a browser, , The client terminal operates in a manner that performs editing of the markup language-based document through a browser.

In the case where the user 1 and the user 2 simultaneously edit the markup language-based document, while the client terminal of the user 2 is editing the markup language-based document through the browser, An editing command is transmitted to the server of the user 1 and the markup language based document of the remote server is synchronized with the markup language based document of the client terminal of the user 2. At the same time, Synchronization between the markup language based document of the server of the user 1 and the markup language based document of the client terminal of the user 1 is performed.

At this time, even when the same editing command is input, the number of dome objects to be subjected to the same editing command may be changed according to the arrangement of a plurality of Document Object Model (DOM) objects included in the markup language-based document , And thus the processing speed of the edit command for the markup language based document may be changed.

For example, an arrangement structure 50 of dome objects 61-64 for representing a markup language-based document 10 consisting of four pages 11-14 is shown in FIG. , A dome object (for example, < g > < < < >) is added between the dome object 2 62 and the dome object 3 63 in the case of inserting a new page between the page 2 (12) (for example, g> 3 </ g> <g> cn </ g> </ g>), modifying <g> 3 </ g> and <g> 4 </ g> to <g> 4 </ g> and <g> 5 </ g>. That is, three dome objects must be modified by an edit command that inserts a new page between page 2 (12) and page 3 (13). Accordingly, in the case of the arrangement structure 50 as shown in FIG. 1, the more the number of pages is, the more the dome object is required to be modified according to the editing command. Accordingly, The speed may be lowered.

Therefore, it is necessary to introduce an optimal dome object arrangement structure and an edit command processing algorithm that can improve the processing speed of the edit command for the markup language-based document.

The web document editing apparatus and method for editing dome objects based on a page change editing command according to the present invention are characterized in that when a page number change edit command is received, The processing speed of the edit command for the markup language based document is improved by changing the number of the first domome objects included in the first domome object container.
