xml_set_default_handler — Set up default handler
Sets the default handler function for the XML parser
parser.
parserThe XML parser.
handler
If null or an empty string is passed, the handler is reset to its default state.
If handler is a callable,
the callable is set as the handler.
If handler is a string,
it can be the name of a method of an object set with
xml_set_object().
The signature of the handler must be:
parserdata
data contains the character data.
This may be the XML declaration, document type declaration,
entities or other data for which no other handler exists.
Always returns true.
For anyone who was also wondering what kind of events this function actually handles:
it's used in cases when an XML comment is found or an additional declaration like an xml-stylesheet. In such cases the data argument contains the whole string as it is, for example:
<!-- this is a comment -->
<?xml-stylesheet title="mystyle" type="text/xsl" href="style.xsl" ?>it seems to me that in PHP5 the function defined as default-handler (using xml_set_default_handler()) doesen't get passed the cdata anymore:
i.e.:
xml_set_element_handler($this->parser, 'parseSTART', 'parseEND');
xml_set_default_handler($this->parser, 'parseDEFAULT');
function parseSTART() { ... }
function parseEND() { ... }
function parseDEFAULT() { ... }
under PHP5, parseDEFAULT will NOT get passed any cdata, but unter PHP4 it will. at least that's my take on the strange stuff (not) happening after migrating to PHP5.
my solution was to add a xml_set_character_data_handler($parser, 'parseDEFAULT'). it worked for me.I have the same issue using two installation of PHP5: on accepts to use the default handler while the other only uses the character_data one.
Maybe a configuration problem...
