It returns a complete tree made of php objects. The drawback right now, you cannot dump it, unless you do it in PHP yourself. Another drawback, you cannot create new nodes and add it. The second solution is to use domxml_new_child() which adds a child to the internal libxml tree.

No, just my stupidity. I'll fix it. Uwe -- Uwe.Steinmann@fernuni-hagen.de Tel: +2331 987 4528 Fax: +2331 987 375
