Well, the script is based on your own XML-tutorial scripts.
One startElement function which returns the XML-tag name and all attributes and their values of it.  The problem is that for some attributs the php-script returns kinda garbage. Like: <class name="TEXT"> is returned as <class name="TEXT9"> 
I've checked the expat lib via their c-interface. But the same prog. in c returns the correct name value pairs.

do-conf:
./configure --with-gd=no --with-pgsql --enable-sysvshm=yes --enable-sysvsem=yes  --with-config-file-path --with-system-regex=yes --with-xml

I'm using php directly from the shell (for some prototyping) and I did not install a php.ini file on this machine. So php behaves on it internal functions.

Here is the xml-file:
<?xml version="1.0"?>
<data>
 <struct name="Groesse">
  <variant name="Preise">
   <type class="CURRENCY">preis</type>
  </variant>
  <type class="TEXT">titel</type>
 </struct>
 <struct name="Produkt">
  <variant name="Groessen">
   <type class="Groesse">groessen</type>
  </variant>
  <type class="TEXT">titel</type>
  <type class="TEXT">artikelnummer</type>
 </struct>
 <struct name="Gruppe">
  <variant name="Produkte">
   <type class="Produkt">produkte</type>
  </variant>
  <type class="TEXT">titel</type>
 </struct>
</data>
