我想制作下面的 graphml(xml) 文件。

<?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>

但是我的代码制作了以下文件

<?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 程序不支持输出文件，因为该文件在<y:ShapeNode xmlns:y="http://graphml.graphdrawing.org/xmlns">.

我想删除部分“xmlns:y="http://graphml.graphdrawing.org/xmlns"

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

如何擦除部分？我应该怎么办？我的源代码如下

    XDocument xDoc = new XDocument();
    XNamespace graphmlNamespace = "http://graphml.graphdrawing.org/xmlns";
    XNamespace xsi = XNamespace.Get("http://www.w3.org/2001/XMLSchema-instance");

只需删除这两行：

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

您的 XML 已经包含定义的默认命名空间：http://graphml.graphdrawing.org/xmlns并ShapeNode在此命名空间中定义。

为什么将 graphmlNamespace 初始化为与您想要的不同的值？如果您希望元素位于名称空间http://www.yworks.com/xml/graphml中，则将它们放在该名称空间中，而不是放在http://graphml.graphdrawing.org/xmlns中。

您明确地重新定义y为其他 ( graphmlNamespace) 命名空间的前缀。您ShapNode和其他带有前缀的节点y:应该在"http://www.yworks.com/xml/graphml"命名空间中。您的代码中需要另一个XNamespace名称空间/前缀。
