Xquery Konstruktoren richtig einsetzen

[lingua]

Hallo wieder,

mein letztes Problem nach der Lösung von allen anderen ist das entsprechende Output zu erzeugen.

Ich will ein Graphml-XLMDokument erzeugen, und irgendwie funktioniert es nicht.
Ich möchte so ein Output bekommen:

<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://graphml.graphdrawing.org/xmlns"
         xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">
   
   <!-- data schema -->
   <key id="self_name" for="node" attr.name="name" attr.type="string"/>
   <key id="child_name" for="node" attr.name="gender" attr.type="string"/>
   <key id="edge_name" for="edge" attr.name="gender" attr.type="string"/>
   
   <graph edgedefault="undirected">
      
      <node id="677">
         <data key="self_name">Konzept</data>
      </node>
      <node id="seg162">
         <data key="child_name"> Subkonzept 1</data>
      </node>
      <node id="seg172">
         <data key="child_name"> Subkonzept 2</data>
      </node>
      <edge source="677" target="seg162">
         <data key="edge_name">Relation</data>
      </edge>
      <edge source="678" target="seg172">
         <data key="edge_name">Relation2</data>
      </edge>
   </graph>
</graphml>

Mein XQuery sieht ungefähr so aus:

xquery version "1.0";

declare boundary-space strip;

declare namespace xsf="http://www.xstandoff.net/2009/xstandoff/1.1";
declare namespace xsi="http://www.w3.org/2001/XMLSchema-instance";

declare namespace dataspace="http://web/dataspace";

declare default element namespace "http://www.xstandoff.net/2009/xstandoff/1.1";

xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">

<!-- data schema -->
   <key id="self_name" for="node" attr.name="name" attr.type="string"/>
   <key id="child_name" for="node" attr.name="gender" attr.type="string"/>
   <key id="edge_name" for="edge" attr.name="gender" attr.type="string"/>
   
{


for $doc in collection("../data/xsf_u8")


let $text := $doc//textualContent

return

for $hd_mod in $doc//label



let $id_dependHead := $xsf_senteces/@id

return 
 
  for $xsf_mod in $doc//cnxde:sentence[@xsf:segment=$attr]

let $xsf_seg_id := $xsf_mod/@xsf:segment

where $xsf_seg_id 
return

let $parent := $xsf_senteces/../..


for $child_label_cnx_seg  in $child_labels/@xsf:segment

   
   for $child_token_seg in $doc//cnxde:analysis
      
        let $child_term := $doc//terms:toc/terms:head  //terms:term[@xsf:segment = $child_token_seg]
        
        where $child_term
        return
            
            <graph edgedefault="undirected">
            
            <node id= "{ $self_nodeid }">
            <data key="self_name">{$self_term}</data>
            </node>
            <node id="{ $child_label_cnx_seg}">
            <data key="child_name">{ $children_term}</data>
            </node>
             <edge source="{$self_nodeid}" target="{ $child_label_cnx_seg}">
                  <data key="edge_name">ATTR</data>
                </edge>
            
            
            </graph>

}
</graphml>

Leider bekomme ich so Folgendes:

<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://graphml.graphdrawing.org/xmlns"
         xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd"><!-- data schema --><key id="self_name" attr.type="string" for="node" attr.name="name"/>
   <key id="child_name" attr.type="string" for="node" attr.name="gender"/>
   <key id="edge_name" attr.type="string" for="edge" attr.name="gender"/>
   <graph edgedefault="undirected">
      <node id="677">
         <data key="self_name">Konzept</data>
      </node>
      <node id="seg162">
          <data key="child_name">Subkonzept 2</data>
      </node>
      <edge source="677" target="seg162">
         <data key="edge_name">Relation 1</data>
      </edge>
      <edge source="677" target="seg162">
         <data key="edge_name">Relation 2</data>
      </edge>
   </graph>
   <graph edgedefault="undirected">
      <node id="677">
         <data key="self_name">Konzept</data>
      </node>
      <node id="seg172">
        
         <data key="child_name">Subkonzept 2</data>
      </node>
      <edge source="677" target="seg172">
         <data key="edge_name">Relation 1</data>
      </edge>
      <edge source="677" target="seg172">
         <data key="edge_name">Relation 2</data>
      </edge>
   </graph>
  </graphml>

Ich zerbreche mir den Kopf, wie soll ich genau die Konstruktoren ({}) einsetzen, damit ich nur einen graph-Knoten mit den dazugehörigen Nodes bekomme.

Danke schon mal vielmals!
