Description
resource 
xml_parser_create_ns ( [string encoding [, string separator]] )
     xml_parser_create_ns() creates a new XML parser
     with XML namespace support and returns a resource handle referencing 
     it to be used by the other XML functions.
    
     With a namespace aware parser tag parameters passed to the
     various handler functions will consist of namespace and tag name
     separated by the string specified in
     seperator or ':' by
     default. 
    
     The optional encoding specifies the character
     encoding for the input/output in PHP 4. Starting from PHP 5, the input
     encoding is automatically detected, so that the
     encoding parameter specifies only the output
     encoding. In PHP 4, the default output encoding is the same as the
     input charset. In PHP 5.0.0 and 5.0.1, the default output charset is
     ISO-8859-1, while in PHP 5.0.2 and upper is UTF-8. The supported
     encodings are ISO-8859-1, UTF-8 and
     US-ASCII.
