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