What XML parser to use with PHP

Question

I want to open and read an XML file using php, but I wont be able to know the names of the elements in the xml file, I will only know the structure. What I want to know is, is there a framework or class build into php which can open the xml file and then loop through the elements and retrieve the name of the element and the text value of the element and a check that returns true if the element has children?

Thanks

Answer 1

You should look at SimpleXML:

http://php.net/manual/en/class.simplexmlelement.php

Take a look here:

http://www.w3schools.com/PHP/php_xml_simplexml.asp

But most importantly, searching SO often has answers to what you need:

Answer 2

SimpleXMLElement

You could also take a look at: http://www.w3schools.com/php/php_xml_simplexml.asp. (maybe Expat too)

Answer 3

the best is

http://www.php.net/dom

it is really easy to use and powerful

all xml implementations in php are libxml based so you need to choose the right API for you

and i think DOM is the easiest and the most complete one!

Yes there is. Buit-in XML functions can be found in the PHP manual, there are a lot:
