The XML functions lets you parse, but not validate, XML documents
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.
