I hadn't noticed that. My php.ini was set to on, changing it to off gave the
warning.
Having changed:
xml_set_object($this->parser,&$this);
to:
xml_set_object($this->parser,$this);
Stops the warning and the parser works fine.
This is the class I'm using and it works fine:
class parse_words_xml {
var $words;
function parse_words_xml($xml_data) {
$this->words = array();
$this->parser = xml_parser_create();
xml_parser_set_option($this->parser, XML_OPTION_CASE_FOLDING, false);
xml_set_element_handler($this->parser,"tag_open","tag_close");
xml_set_character_data_handler($this->parser,"cdata");
$this->parse($xml_data);
}
function parse($xml_data) {
xml_set_object($this->parser,$this);
reset ($xml_data);
while (list (, $data) = each ($xml_data)) {
if (!xml_parse($this->parser, $data)) {
die(sprintf( "XML error: %s at line %d\n\n",
xml_error_string(xml_get_error_code($this->parser)),
xml_get_current_line_number($this->parser)));
}
}
}
function tag_open($parser,$tag,$attributes) {
$this->current_tag = $tag;
switch($tag){
case 'Word':
$this->id = $attributes['id'];
$this->words[$attributes['id']] = 1;
break;
default:
break;
}
}
function cdata($parser,$cdata) {
$this->temp = $cdata;
}
function tag_close($parser,$tag) {
switch($tag){
case 'Word':
$this->words[$this->id] = $this->temp;
$this->temp = '';
break;
default:
break;
}
}
}
