The XML functions lets you parse, but not validate, XML
documents.
XML is a data format for standardized structured document
exchange. More information on XML can be found in our
XML Tutorial.
This extension uses the Expat XML parser.
Expat is an event-based parser, it views an XML document as a
series of events. When an event occurs, it calls a specified
function to handle it.
Expat is a non-validating parser, and ignores any DTDs linked
to a document. However, if the document is not well formed it
will end with an error message.
Because it is an event-based, non validating parser, Expat is
fast and well suited for web applications.
The XML parser functions lets you create XML parsers and
define handlers for XML events.
The XML functions are part of the PHP core. There is no
installation needed to use these functions.
