the DOM and XML functions for PHP5?

Question

i've read that you could use the DOMdocument class in php5 to manipulate XML documents. and also the XML functions.

where can i find documentation for the DOMdocument class with all its methods? and the same with XML functions?

are these the only things i need to learn when handling (creating and reading) xml documents with php5?

btw: there are xml_parser, xmlwriter, domxml, simplexml and so on built in into php5. which function set should i use??

Answer 1

DOMDocument documentation
