XML parsing problems..

I didn't see any responses to this the other day when I asked so this time I'll include source.. just cutting and pasting so hopefully nothing gets clobbered.. When I parse this lil bit of raw data it parses properly. You can trace it and see that it opens and closes the tags properly and that it writes the $this->dom variable properly in the parsers close_tag () function. However when you return the $this->dom value afterwards the variables previous value is returned rather than the current value. Any ideas what I am doing wrong? Thanks. <? //index file include_once ( 'common.inc' ); // does all my settings and includes.. in this case includes the below classes $raw = "<HTML><HEAD><TITLE>Howdy!</TITLE></HEAD>"; $raw .= "<BODY BGCOLOR='RED'>My dog is cute. My cat is cute.</BODY></HTML>"; $xml_parser = new xml_parser; $document = $xml_parser->parse ( $raw ); print "<PRE>"; print_r ( $document ); print "</PRE>"; ?> <? // classes file.. class xml_parser {
