xml_set_element_handler -- set up start and end element handlers
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:
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.
