没有错误：但是通过Javax.xml.transform没有发生XSLT转换

Question

XSLT在线测试并且工作正常，但在Java上运行时，对XML没有任何影响，并且在服务器控制台上没有报告错误

请参考XML onl Link。当我在http://xsltransform.net上测试时，我通过XSLT转换获得了正确的结果。但是当我在Java上应用相同的XSLT时，没有任何转换发生，并且服务器控制台上也没有错误。

使用的库

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.Node;
import org.w3c.dom.Element;

Java代码

         File fXmlFile = new File("C:\\Java\\Web Project\\Merged_Excel\\WebContent\\source\\XML\\XML_Template.xml");

          DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
          dbFactory.setNamespaceAware(true);
          DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
          doc = (Document) dBuilder.parse(fXmlFile);

          doc.getDocumentElement().normalize();

              Transformer trans = factory.newTransformer(stylesource);

              System.out.println(writer.toString());

以下变化解决了问题（不知道根本原因）

1.对setnamespace感知错误

dbFactory.setNamespaceAware(false);

2.从xslt字符串中删除命名空间标识符

String sorter="<?xml version=\"1.0\" encoding=\"utf-8\"?>"+
                            "<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\">"+
                            "  <xsl:output method=\"xml\" encoding=\"utf-8\" indent=\"yes\"/>"+
                            "  <xsl:template match=\"@* | node()\">"+
                            "    <xsl:copy>"+
                            "      <xsl:apply-templates select=\"@* | node()\"/>"+
                            "    </xsl:copy>"+
                            "  </xsl:template>"+
                            "  <xsl:template match=\"Row\">"+ //if namespace sensitive then use ss:Row
                            "    <xsl:copy>"+
                            "      <xsl:apply-templates select=\"*\">"+
                            "        <xsl:sort select=\"@Index\" order=\"ascending\" data-type=\"number\"/>"+ //if namespace sensitive then use ss:Index
                            "      </xsl:apply-templates>"+
                            "    </xsl:copy>"+
                            "  </xsl:template>"+
                            "</xsl:stylesheet>";
