Sets the character data handler function for the XML parser parser.
A reference to the XML parser to set up character data handler function.
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 two parameters:handler( XMLParser$parser, string$data ):
The first parameter, parser, is a reference to the XML parser calling the handler.
The second parameter, data, contains the character data as a string.
Character data handler is called for every piece of a text in the XML document. It can be called multiple times inside each fragment (e.g. for non-ASCII strings).
If a handler function is set to an empty string, or false, the handler in question is disabled.
Instead of a function name, an array containing an object reference and a method name can also be supplied.
Returns true on success or false on failure.
