我已经阅读了很多文章并尝试了很多方法，但仍然无法让 xsl 在参数中查找值。我从 java 的 sun xalan 开始，但从来没有让它工作过，所以我切换到 saxon 无济于事。我想用 xls 将两个 xml 文档合二为一。从不在文件系统上，这是用于构建 xml 字符串/文档的 Web 应用程序。我尝试将 DTMAxisIterator、DomSource 和 Doc 传递给 xsl 中的节点集，字符串。它在带有 xsl document() 的 NotePad++ 中运行良好，但我不想将 xml 保存在系统上。

XSL

<xsl:template match="/policy/vehicles">

类

    public String transformResultXML(String xmlSource, Templates xsl,String policyXml ) {
       String result = "";  

    try {

          StringWriter writer = new StringWriter();
          StringReader reader2 = new StringReader(policyXml);

          XmlHelper xh = new XmlHelper();
          Document xmlSrc = xh.loadDoc(xmlSource);
          DOMSource source = new DOMSource(xmlSrc);


          ByteArrayInputStream byteStream = new  ByteArrayInputStream(xmlSource.getBytes());
          StringReader reader = new StringReader(xmlSource);
          SAXSource source2 = new SAXSource(new XMLFilterImpl(), new  InputSource(reader));

          TransformerFactory transFact = new com.icl.saxon.TransformerFactoryImpl();

          Transformer transformer = transFact.newTransformer();

          transformer.setParameter("RsXml",source2);
         // transformer.setParameter("RsXml",xmlSrc);
          transformer.setOutputProperty(OutputKeys.INDENT, "yes");
          transformer.transform(new javax.xml.transform.stream.StreamSource(reader2),
                  new javax.xml.transform.stream.StreamResult(writer));
          result = writer.toString();
          System.out.println(result);

    } catch( Exception e ) {
        e.printStackTrace();
    }

    return result;
}   

最佳答案

我能够让它与 Saxon 一起工作，请参阅下面的代码。我认为关键是 document.getDocumentElement() 作为参数

      public String transformResultXML(String xmlSource, Templates xsl,String policyXml )    {
       String result = "";  

    try {

          StringWriter writer = new StringWriter();
          StringReader reader2 = new StringReader(policyXml);

          DocumentBuilderFactory dfactory =
                  DocumentBuilderFactory.newInstance( "com.icl.saxon.om.DocumentBuilderFactoryImpl",null);

          dfactory.setNamespaceAware(true);

          DocumentBuilder docBuilder = dfactory.newDocumentBuilder();

          org.w3c.dom.Document document = docBuilder.parse(new InputSource(new StringReader(xmlSource)));

          Transformer transformer = xsl.newTransformer();

          transformer.setParameter("RsXml", document.getDocumentElement());

          transformer.setOutputProperty(OutputKeys.INDENT, "yes");
          transformer.transform(new javax.xml.transform.stream.StreamSource(reader2),
                  new javax.xml.transform.stream.StreamResult(writer));
          result = writer.toString();
          System.out.println(result);

    } catch( Exception e ) {
        e.printStackTrace();
    }

XSL 片段

    <xsl:param name="RsXml" />

<xsl:template match="/policy/vehicles">


        <xsl:for-each select="$RsXml/InsuranceSvcRs/com.csc_PolicyOrderCurrentCarrierInqRs/PersVeh">

关于java - 将 xml 文档作为参数传递给 xsl，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13381698/
