我有一个带有标签的 xml 文件。

<ENVELOPE>
    <A>Hi

    <A1>
        <A12>groupA</A12>
        <A13></A13>
    </A1>
    <B>
        <A>xxx</A>

我想以以下格式存储这些数据

Col Header A    A1         B   C-A11
           Hi   groupA    xxx   100   
           Hi   groupA    yyy   1000    
           Hi   groupA    zzz   100     
          Hello groupB    rrr   10000

试过源代码：

   DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
  domFactory.setNamespaceAware(true); 
  DocumentBuilder builder = domFactory.newDocumentBuilder();
  Document doc = builder.parse("Response.xml");
  XPath xpath = XPathFactory.newInstance().newXPath();
  // XPath Query for showing all nodes value

  ArrayList names = new ArrayList();

  XPathExpression expr1 = xpath.compile("//A/text()");

  Object res = expr1.evaluate(doc, XPathConstants.NODESET);
  NodeList nod = (NodeList) res;

  for (int i = 0; i < nod.getLength(); i++) {
      System.out.print(i+":");
        System.out.println(nod.item(i).getNodeValue()); 
        if(!names.contains(nod.item(i).getTextContent().trim()))
            names.add(nod.item(i).getTextContent().trim());
 }

  NodeList nodeLst = doc.getElementsByTagName("C");

   int coun = nodeLst.getLength();
   String val[][] = new String[coun][2];
  for (int s = 0; s < nodeLst.getLength(); s++) {
     Node secNode = nodeLst.item(s);

     if (secNode.getNodeType() == Node.ELEMENT_NODE) {
       try
              {
                Element amtval = (Element) secNode;
                NodeList secval = amtval.getElementsByTagName("A11");
                val[s][0] = secval.item(0).getTextContent();
                    System.out.println("A11 :" + val[s][0]);

                NodeList lstNmElmntLst = amtval.getElementsByTagName("A13");
                val[s][1] = lstNmElmntLst.item(0).getTextContent();
                    System.out.println("A13 : " +val[s][1]);
              }
              catch(Exception ex){
                  ex.printStackTrace();
             }
     }
  }

   NodeList plamt = doc.getElementsByTagName("A1");

   int count = plamt.getLength();
   String val1[][] = new String[count][2];
  for (int s = 0; s < plamt.getLength(); s++) {
      Node secNode = plamt.item(s);

     //if (secNode.getNodeType() == Node.ELEMENT_NODE)
     {
       try
              {
                Element amtval = (Element) secNode;
                NodeList secval = amtval.getElementsByTagName("A12");
                val1[s][0] = secval.item(0).getTextContent();
                    System.out.println("A12 :" + val1[s][0]);

                NodeList lstNmElmntLst = amtval.getElementsByTagName("A13");
                val1[s][1] = lstNmElmntLst.item(0).getTextContent();
                    System.out.println("A13: " +val1[s][1]);
              }
              catch(Exception ex){
                  ex.getMessage();
             }
     }

我得到低于输出

Hi      100     100
xxx     100         100
yyy     100         100
zzz     100         100
Hello   groupA  groupB
rrr     groupC  groupD
  1. 怎样才能得到上述格式。
  2. 有没有可用于分组的参考资料？
  3. 请提供任何逻辑来帮助我。在此先感谢， 中国 P.

我当然不会在导航 Java 代码中尝试这样做——XSLT 解决方案会容易得多。我认为是这样的：

<xsl:for-each select="B">
  <tr>
    <td><xsl:value-of select="preceding-sibling::A[1]"/></td>
    <td><xsl:value-of select="preceding-sibling::A1[1]"/></td>
    <td><xsl:value-of select="child::A"/></td>
    <td><xsl:value-of select="following-sibling::C[1]/A11"></td>
  </tr>
</xsl:for-each>
