xml格式的流輸出GEPHI-TOOLKIT

Question

我正在使用gephi-toolkit編寫Java函數，該函數應生成gefx格式的圖形數據，作為輸出流而不是文件，以供進一步使用。

如果我使用CharArrayWriter或StringWriter-所有xml標記都被格式化為特殊符號，則我的輸出如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<gexf xmlns="http://www.gexf.net/1.2draft" version="1.2" xmlns:viz="http://www.gexf.net/1.2draft/viz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.gexf.net/1.2draft http://www.gexf.net/1.2draft/gexf.xsd">
  <meta lastmodifieddate="2016-03-24">

    <description></description>
  </meta>
  <graph defaultedgetype="directed" mode="static">
    <nodes>
      <node id="1" label="n0">
        <attvalues></attvalues>
        <viz:size value="10.0"></viz:size>
        <viz:position x="-206.8857" y="-18.469671" z="0.0"></viz:position>
        <viz:color r="153" g="153" b="153"></viz:color>
      </node>
      <node id="2" label="n1">
        <attvalues></attvalues>
        <viz:size value="10.0"></viz:size>
        <viz:position x="-29.136229" y="80.29351" z="0.0"></viz:position>
        <viz:color r="153" g="153" b="153"></viz:color>

我應該使用什么來在輸出中獲取xml-stream數據？

當前代碼：

//Export 
ExportController ec = Lookup.getDefault().lookup(ExportController.class); 

ExporterGEXF exp = (ExporterGEXF) ec.getExporter("gexf");  
CharArrayWriter writer = new CharArrayWriter(); 

ec.exportWriter(writer, exp); 
return writer;

感謝哈倫 ！

工作代碼是：

 StringWriter strwriter = new StringWriter();



        ec.exportWriter(strwriter, (CharacterExporter)exp);

        String str = strwriter.getBuffer().toString();



        byte[] arr = str.getBytes("UTF-8");

          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    return builder.parse(new ByteArrayInputStream(arr));
