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...
