Analysis on how to use various PHP syntax parsing functions

In

Pear also seems to have such parsing classes. In addition, you can search for php parsing on the Internet and find various php parsing xml classes compiled by yourself.

DOM function is a model function of the Document Object. It is a relatively low-level XML operation. Like C #'s XML operations, you need to write a lot of code whether you write or read an XML file.

The XML Parser (sax) in the PHP syntax parsing function is a function library at the top level. You need to build three functions by yourself and use these three functions directly to return data, logic with strong requirements. When processing xml with different structures, we need to re-construct these three functions. This is an uncomfortable place for many users.

Very good, so I wrote the XML operation class myself. It is generally a combination of sax and DOM to solve the bad DOM and SAX and adapt to their own needs.

Xml analysis mainly involves the methods of sax and dom, which are highly efficient and dom-based.

Php syntax parsing functions in the PHP Library

Dom/dom xml/simple xml libraries are based on dom
Xml parser is based on sax

The XML Syntax Parsing function of php is an xml universal interface function set based on expat. Dom xml converts xml documents into objects through expat, so that users can operate xml documents as objects. SimpleXM provides an efficient method for retrieving xml documents. Other methods include xslt and xpath.

You can select one or more PHP syntax parsing functions as needed.
