PHP: Manual: xml_set_element

Description

int xml_set_element_handler (int parser, string startElementHandler, string endElementHandler)

Sets the element handler functions for the XML parser parser. startElementHandler and endElementHandler are strings containing the names of functions that must exist when xml_parse() is called for parser.

The function named by startElementHandler must accept three parameters:

startElementHandler (int parser, string name, array attribs)

parser

The first parameter, parser, is a reference to the XML parser calling the handler.

name

The second parameter, name, contains the name of the element for which this handler is called. If case-folding is in effect for this parser, the element name will be in uppercase letters.

attribs

The third parameter, attribs, contains an associative array with the element's attributes (if any). The keys of this array are the attribute names, the values are the attribute values. Attribute names are case-folded on the same criteria as element names. Attribute values are not case-folded.

The original order of the attributes can be retrieved by walking through attribs the normal way, using each(). The first key in the array was the first attribute, and so on.

The function named by endElementHandler must accept two parameters:

endElementHandler (int parser, string name)

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
name: The second parameter, name, contains the name of the element for which this handler is called. If case-folding is in effect for this parser, the element name will be in uppercase letters.

If a handler function is set to an empty string, or false, the handler in question is disabled.

True is returned if the handlers are set up, false if parser is not a parser.

There is currently no support for object/method handlers. See xml_set_object() for using the XML parser within an object.
