How to remove "xmlns:y" in this case?

Question

I want to make the below graphml(xml) file.

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<graphml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:y="http://www.yworks.com/xml/graphml" schemaLocation="http://graphml.graphdrawing.org/xmlns http://www.yworks.com/xml/schema/graphml/1.1/ygraphml.xsd" xmlns="http://graphml.graphdrawing.org/xmlns">
  <key for="node" id="d3" yfiles.type="nodegraphics" />
  <graph edgedefault="directed" id="G">
    <node id="3">
      <data key="d3">
        <y:ShapeNode>
          <y:Geometry height="50" width="50" x="80" y="0" />
          <y:BorderStyle color="#000000" type="line" width="1.0" />
          <y:NodeLabel alignment="center" autoSizePolicy="content">TEST</y:NodeLabel>
        </y:ShapeNode>
      </data>
    </node>
    <node id="1000">
      <data key="d3">
        <y:ShapeNode>
          <y:Geometry height="50" width="50" x="240" y="0" />
          <y:BorderStyle color="#000000" type="line" width="1.0" />
          <y:NodeLabel alignment="center" autoSizePolicy="content">TEST</y:NodeLabel>
        </y:ShapeNode>
      </data>
    </node>
  </graph>
</graphml>

But my code made the below file

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<graphml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:y="http://www.yworks.com/xml/graphml" schemaLocation="http://graphml.graphdrawing.org/xmlns http://www.yworks.com/xml/schema/graphml/1.1/ygraphml.xsd" xmlns="http://graphml.graphdrawing.org/xmlns">
  <key for="node" id="d3" yfiles.type="nodegraphics" />
  <graph edgedefault="directed" id="G">
    <node id="3">
      <data key="d3">
        <y:ShapeNode xmlns:y="http://graphml.graphdrawing.org/xmlns">
          <y:Geometry height="50" width="50" x="80" y="0" />
          <y:BorderStyle color="#000000" type="line" width="1.0" />
          <y:NodeLabel alignment="center" autoSizePolicy="content">TEST</y:NodeLabel>
        </y:ShapeNode>
      </data>
    </node>
    <node id="1000">
      <data key="d3">
        <y:ShapeNode xmlns:y="http://graphml.graphdrawing.org/xmlns">
          <y:Geometry height="50" width="50" x="240" y="0" />
          <y:BorderStyle color="#000000" type="line" width="1.0" />
          <y:NodeLabel alignment="center" autoSizePolicy="content">TEST</y:NodeLabel>
        </y:ShapeNode>
      </data>
    </node>
  </graph>
</graphml>

Graphml program can not support the output-file because the file have the part "xmlns:y="http://graphml.graphdrawing.org/xmlns" in <y:ShapeNode xmlns:y="http://graphml.graphdrawing.org/xmlns">.

I want to erase the part "xmlns:y="http://graphml.graphdrawing.org/xmlns" in

<y:ShapeNode xmlns:y="http://graphml.graphdrawing.org/xmlns">

How to erase the part? What should I do? My source code is below

Both XML samples look the same to me... Can you make difference more explicit? — Alexei Levenkov, Nov 14 '12 at 02:33
The difference is . First file have just , but the other file have . — user1822545, Nov 14 '12 at 02:42
yEd (Graphml application) can not normally load my file because of the part xmlns:y=~~~~ in — user1822545, Nov 14 '12 at 02:45

Simply remove these two lines:

XAttribute sub4Attrib_yShapeNode1 = new XAttribute(XNamespace.Xmlns + "y", graphmlNamespace);
sub4Element_yShapeNode.Add(sub4Attrib_yShapeNode1);

Your XML already contains defined default namespace: http://graphml.graphdrawing.org/xmlns and ShapeNode is defined in this namespace.

I'm not sure if it helps as nodes need to be in 2 namespaces, while only one is defined in the code... But you may be right - way too much code for sample to be sure... – Alexei Levenkov Nov 14 '12 at 03:15
@AlexeiLevenkov, What do you mean? According to provided XML `ShapeData` is defined in `http://graphml.graphdrawing.org/xmlns`. So there is no need to specify namespace inside it, because XML has default namespace as `http://graphml.graphdrawing.org/xmlns`. According to XML spec both XMLs are correct, so it is issue of OP's XML parser. – Kirill Polishchuk Nov 14 '12 at 03:19
`y:ShapeNode` in first XML has "http://www.yworks.com/xml/graphml" as namespace... not the "http://graphml.graphdrawing.org/xmlns" which is using empty namespace prefix. – Alexei Levenkov Nov 14 '12 at 06:11

Why have you initialized graphmlNamespace to a different value from the one you want? If you want the elements to be in namespace http://www.yworks.com/xml/graphml, then put them in that namespace, not in http://graphml.graphdrawing.org/xmlns.

You are explicitly redefining y to be prefix of other (graphmlNamespace) namespace. You ShapNode and other nodes with y: prefix should be in "http://www.yworks.com/xml/graphml" namespace. You need another XNamespace for that namespace/prefix in your code.
