xml_set_element_handler -- Set up start and end element handlers

Description

bool xml_set_element_handler ( resource parser, callback start_element_handler, callback end_element_handler )

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

The function named by start_element_handler must accept three parameters: start_element_handler ( resource 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 end_element_handler must accept two parameters: end_element_handler ( resource 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.
