    This documentation is not finished yet. Don't start to translate it
    or use it as a programming reference (steinm@php.net).
   </simpara>
   <simpara>
    These functions are only available if PHP was configured with
    <option role="configure">--with-dom=[DIR]</option>, using the
    <ulink url="&url.domxml;">GNOME xml library</ulink>.
    You will need at least libxml-2.2.7
    These functions have been added in PHP 4.
   </simpara>
   <simpara>
    The extension allows you to operate on an XML document with the DOM API.
    It also provides a function <function>xmltree</function> to turn the
    complete XML document into a tree of PHP objects. Currently this
    tree should be considered read-only - you can modify it but this
    would not make any sense since <function>dumpmem</function> cannot be
    applied to it. Therefore, if you want to read an XML file and write
    a modified version use the <function>add_node</function>,
    <function>set_attribute</function>, etc. and finally
    <function>dumpmem</function> functions.

    Each function in this extension can be used in two ways. In a non-object
    oriented way by passing the object to apply the function to as a first
    argument, or in an object oriented way by calling the function as a method
    of an object. This documentation describes the non-object oriented
    functions, though you get the object methods by skipping the prefix
    "domxml_".

     If we take the example from <function>domxml_add_root</function> it
     is simple to add an attribute to the HEAD element by the simply calling
     the <function>set_attribute</function> function of the node class.
     <example>
      <title>Adding an attribute to an element</title>
      <programlisting role="php">
<![CDATA[
<?php
$doc = new_xmldoc("1.0");
$root = $doc->add_root("HTML");
$head = $root->new_child("HEAD", "");
$head->new_child("TITLE", "Hier der Titel");
$head->set_attribute("Language", "ge");
echo $doc->dumpmem();

     In the following example the variable <varname>children</varname> will
     contain an array with one node of type XML_ELEMENT. This node is
     the TITLE element.

      <title>Adding an attribute to an element</title>
