Best XML Parser for PHP

Question

I have used the XML Parser before  and even though it worked OK  I wasn t happy with it in general  it felt like I was using workarounds for things that should be basic functionality   I recently saw SimpleXML but I haven t tried it yet  Is it any simpler  What advantages and disadvantages do both have  Any other parsers you ve used

I would have to say SimpleXML takes the cake because it is firstly an extension  written in C  and is very fast   But second  the parsed document takes the form of a PHP object   So you can  query  like  root- gt myElement

It depends on what you are trying to do with the XML files  If you are just trying to read the XML file  like a configuration file   The Wicked Flea is correct in suggesting SimpleXML since it creates what amounts to nested ArrayObjects  e g  value will be accessible by  xml- root- child   If you are looking to manipulate the XML files you re probably best off using DOM XML

the crxml parser is a real easy to parser   This class has got a search function  which takes a node name with any namespace as an argument  It searches the xml for the node and prints out the access statement to access that node using this class  This class also makes xml generation very easy   you can download this class at  http   freshmeat net projects crxml  or from phpclasses org  http   www phpclasses org package 6769-PHP-Manipulate-XML-documents-as-array html

Have a look at PHP s available XML extensions   The main difference between XML Parser and SimpleXML is that the latter is not a pull parser  SimpleXML is built on top of the DOM extensions and will load the entire XML file into memory  XML Parser like XMLReader will only load the current node into memory  You define handlers for specific nodes which will get triggered when the Parser encounters it  That is faster and saves on memory  You pay for that with not being able to use XPath   Personally  I find SimpleXml quite limiting  hence simple  in what it offers over DOM  You can switch between DOM and SimpleXml easily though  but I usually dont bother and go the DOM route directly  DOM is an implementation of the W3C DOM API  so you might be familiar with it from other languages  for instance JavaScript
