xml_set_external_entity_ref_handler -- set up external entity reference handler
Description
int xml_set_external_entity_ref_handler (int parser, string
handler)
Sets the notation declaration handler function for the XML parser parser.
handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
The function named by handler must accept five parameters, and should
return an integer value. If the value returned from the handler is FALSE (which it
will be if no value is returned), the XML parser will stop parsing and xml_get_error_code() will return
XML_ERROR_EXTERNAL_ENTITY_HANDLING.
int handler (int parser, string openEntityNames, string base,
string systemId, string publicId)
- parser
-
The first parameter, parser, is a reference to the XML parser calling the
handler.
- openEntityNames
-
The second parameter, openEntityNames, is a space-separated list of the
names of the entities that are open for the parse of this entity (including the name of the
referenced entity).
- base
-
This is the base for resolving the system identifier (systemid) of the
external entity. Currently this parameter will always be set to an empty string.
- systemId
-
The fourth parameter, systemId, is the system identifier as specified in
the entity declaration.
- publicId
-
The fifth parameter, publicId, is the public identifier as specified in
the entity declaration, or an empty string if none was specified; the whitespace in the public
identifier will have been normalized as required by the XML spec.
If a handler function is set to an empty string, or FALSE, the handler in
question is disabled.
TRUE is returned if the handler is set up, FALSE if
parser is not a parser.
Note: Instead of a function name, an array containing an object reference and a method
name can also be supplied.
