感觉dom4j的xslt支持好想有问题哦

//src.xml
<?xml version="1.0" encoding="UTF-8"?>
<source>
  <title>XSL</title>
  <author>John Smith</author>
</source>

//engine.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <h1>
      <xsl:value-of select="//title"/>
    </h1>
    <h2>
      <xsl:value-of select="//author"/>
    </h2>
  </xsl:template>
</xsl:stylesheet>

//work codes
  public static Document transformDocument(Document document, File styleSheet)
    throws TransformerException
  {
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer transformer =
      factory.newTransformer(new StreamSource(styleSheet));

    DocumentSource source = new DocumentSource(document);
    DocumentResult result = new DocumentResult();
    transformer.transform(source, result);

    Document transformedDoc = result.getDocument();

    return transformedDoc;
  }

程序跑起来后报错如下：
javax.xml.transform.TransformerException: org.dom4j.IllegalAddException: The node "org.dom4j.tree.DefaultElement@ad5fab [Element: <h1 attributes: []/>]" could not be added to the branch "null" because: Cannot add another element to this Document as it already has a root element of: h1

而我把//engine.xsl改为如下：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <xsl:value-of select="//title"/>
    <xsl:value-of select="//author"/>
  </xsl:template>
</xsl:stylesheet>
也就是去掉了那些HTML标签

转换没有报错，算是成功了，但是查看//target.xml时发现，target.xml只有一个header，没有任何内容了，真是奇怪
//target.xml
<?xml version="1.0" encoding="UTF-8"?>
