There are two similar problems in the functions startElement() and endElement() in example 2 on <http://us2.php.net/xml>.

1) $htmltag, which springs into existence out of nowhere, is being used in a comparison. I think it was meant to be $name rather than $htmltag.

2) I think the following lines:

   if ($htmltag == $map_array[$name]) {
       echo "<$htmltag>";

should be:

   if ( isset($map_array[$name]) ) {
       echo "<$map_array[$name]>";

Otherwise the output will be identical to the input (no conversion).
