When using SAX, you must build 3 functions yourself, and use these three functions to return data, require strong logic. When processing XML of different structures, it is necessary to re-construct these three functions. trouble!
With the DOM mode, it is better, but he regards each node as a node, to operate a lot of code, trouble!
There are a lot of open source XML parses for the online source. I have seen a few, but my heart always feels not practical, I feel that I always follow the buttocks of others.
In these few days, I was very tired, so I decided to change my head, write some PHP code. In order to prevent the XML parsing process, I spent a day, I spent a day, I wrote the following XML parsing class, then With the following things,
The implementation is achieved by packaging the "resolution of SAX mode". In general, for my personal, performance is also possible, basically can complete most of the processing requirements.
Function: 1 / Query / Add / Modify / Delete Work. 2 / Export All Data of the XML file into an array .3 / The entire design uses the OO method, when the results set, How to use Similar to DOM
Disadvantages: 1 / Each node is best with an ID (see later example), each "node name" = "tag _ node ID", if this ID value is not set, the program will automatically give him Generate an ID, this ID is the position number of this node in his superior node, starting from 0. 2 / Query a node can be done by connecting "Node Node" with "|" symbol. These "node names" are the names of the superior nodes written in sequence.
Instructions for use: Run the following example, you can see the instructions of the function on the execution result page
The code is implemented by PHP5, and it is not possible to run in PHP4.
Since I just finished, I didn't organize the document. The following example demonstrates only part of the function, the code is not very difficult, if you want to know more features, you can study the research source code.
