 i create this xml from mapguide studio. i intend to create a new layer
programatically using this xml file that calling from
change_layers_via_dom.php code sample. what i do here is changed
DOMDocument::Load to load my xml file and also change a node value that
satisfy my query.

    $domDocument = DOMDocument::load('RecentlyBuilt.LayerDefinition.xml');
    if ($domDocument == NULL)
    {
        echo "The layer definition
          'RecentlyBuilt.LayerDefinition' could not be
          found.<BR>\n";
        return;
    }

    // Change the filter
    $xpath = new DOMXPath($domDocument);
    $query = '//AreaRule/Filter';
    // Get a list of all the <AreaRule><Filter> elements in the XML.   
    $nodes = $xpath->query($query);
    // Find the correct node and change it
    foreach ($nodes as $node )
    {
        if ($node->nodeValue == 'FeatId > 10')
        {
            $node->nodeValue = 'FeatId > 10';
        }
    }

    // Change the legend label
    $query = '//LegendLabel';
    // Get a list of all the <LegendLabel> elements in the
    // XML.
    $nodes = $xpath->query($query);
    // Find the correct node and change it
    foreach ($nodes as $node )
    {
        if ($node->nodeValue == 'FeatId > 10')
        {
            $node->nodeValue = 'FeatId > 10';
        }
    }

    // --------------------------------------------------//
  // ...
  
    // Add the layer to the map
    $layerDefinition = $domDocument->saveXML();
    $newLayer = add_layer_definition_to_map($layerDefinition,
"RecentlyBuilt", "FeatId > 10", $sessionId, $resourceService, $map);
    add_layer_to_group($newLayer, "Analysis", "Analysis", $map);

    // --------------------------------------------------//
    // Turn off the "Square Footage" themed layer (if it
    // exists) so it does not hide this layer.
    $layerCollection = $map->GetLayers();
    if ($layerCollection->Contains("SquareFootage"))
    {
        $squareFootageLayer =
          $layerCollection->GetItem("SquareFootage");
        $squareFootageLayer->SetVisible(false);
    }

    // --------------------------------------------------//
    // Turn on the visibility of this layer.
    // (If the layer does not already exist in the map, it will be visible
by default when it is added.
    // But if the user has already run this script, he or she may have set
the layer to be invisible.)
    $layerCollection = $map->GetLayers();
    if ($layerCollection->Contains("RecentlyBuilt"))
    {
        $recentlyBuiltLayer = $layerCollection->GetItem("RecentlyBuilt");
        $recentlyBuiltLayer->SetVisible(true);
    }


 Once i ran the code, there is nothing happened. then i copy the link to new
browser, but it show this error message 

ERROR: The new XML document is invalid.

Can you tell me what is my problem?
