xml_set_element_handler — Set up start and end element handlers
$parser
, callable $start_element_handler
, callable $end_element_handler
)
Sets the element handler functions for the XML 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.
parserA reference to the XML parser to set up start and end element handler functions.
start_element_handler
The function named by start_element_handler
must accept three parameters:
$parser
, string $name
, array $attribs
)parsernamename, 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.
attribsattribs, 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.
Note: Instead of a function name, an array containing an object reference and a method name can also be supplied.
end_element_handler
The function named by end_element_handler
must accept two parameters:
$parser
, string $name
)parsernamename, 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.
Returns TRUE on success or FALSE on failure.
