我有一个包含大量信息的原子提要，我想将所需的信息转换为XML。 java代码已经完成，但我无法为此转换创建样式表。

      </entry>
      </feed>

使用的样式表： 

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet 
    xmlns:atom="http://www.w3.org/2005/Atom"
    xmlns:wwe="http://release.wwe.com/atom/1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

    <xsl:strip-space elements="*"/>

    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="/">
        <xsl:apply-templates select="/atom:feed/atom:entry[wwe:asset_type='Video']"/>       
    </xsl:template>

    <!-- this template will delete the target nodes -->
    <xsl:template match="/atom:feed/atom:entry[wwe:asset_type='Video']/atom:id|/atom:feed/atom:entry[wwe:asset_type='Video']/atom:updated|/atom:feed/atom:entry[wwe:asset_type='Video']/atom:category"/>

</xsl:stylesheet>

结果： 

<entry xmlns="http://www.w3.org/2005/Atom" xmlns:wwe="http://release.wwe.com/atom/1.0">
<title>The Most Shocking Tables, Ladders &amp; Chairs Moments</title>
<category term="Non-Branded"/>
<wwe:asset_type>Video</wwe:asset_type>

<wwe:seconds>2</wwe:seconds>

</entry>

我真正需要的是什么： 

<rss xmlns="http://www.w3.org/2005/Atom" xmlns:wwe="http://release.wwe.com/atom/1.0">
    <channel>
        <title><![CDATA[WWE Syndication Feed]]></title>

我认为这个简单的样式表可以解答您的问题：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet 
    xmlns:atom="http://www.w3.org/2005/Atom"
    xmlns:wwe="http://release.wwe.com/atom/1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:media="wwww.yourmedia.com"
    exclude-result-prefixes="atom"
    version="1.0">

    <xsl:strip-space elements="*"/>

    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="/">
        <rss xmlns="http://www.w3.org/2005/Atom">
            <xsl:element name="title" namespace="http://www.w3.org/2005/Atom"/>
            <xsl:element name="link" namespace="http://www.w3.org/2005/Atom"/>
            <xsl:element name="description" namespace="http://www.w3.org/2005/Atom"/>
            <xsl:for-each select="/atom:feed/atom:entry[*[local-name()='asset_type'][.='Video']]">
                <xsl:element name="item" namespace="http://www.w3.org/2005/Atom">
                    <xsl:apply-templates select="atom:title"/>
                    <xsl:apply-templates select="atom:category"/>
                    <xsl:if test="atom:link">
                        <media:group>
                            <xsl:apply-templates select="atom:link[@type='video/mp4']"/>
                            <xsl:apply-templates select="atom:link[@type='image/jpeg']"/>
                        </media:group>
                    </xsl:if>
                </xsl:element>
            </xsl:for-each>
        </rss>
    </xsl:template>

   <xsl:template match="atom:link">
       <media:content>
           <xsl:apply-templates select="@*[not(name()='rel')]"/>
       </media:content>
   </xsl:template>

</xsl:stylesheet>

试试这个

    <?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                exclude-result-prefixes="msxsl wwe test atom"
                xmlns:test="http://test.com/atom/1.0"
                xmlns:atom="http://www.w3.org/2005/Atom"
                xmlns:wwe="http://release.wwe.com/atom/1.0"
                version="1.0">
  <xsl:template match="/">
    <good>
      <xsl:for-each select="atom:feed/atom:entry">
        <assettype>
          <xsl:if test="test:asset_type='VIDEO'">
            <xsl:copy-of select="current()"/>
          </xsl:if>
          <xsl:if test="wwe:asset_type='VIDEO'">
            <xsl:copy-of select="current()"/>
          </xsl:if>
          <xsl:if test="test:asset_type='Video'">
            <xsl:copy-of select="current()"/>
          </xsl:if>
          <xsl:if test="wwe:asset_type='Video'">
            <xsl:copy-of select="current()"/>
          </xsl:if>
        </assettype>
      </xsl:for-each>
    </good>
  </xsl:template>
</xsl:stylesheet>

你的xml是无效的，因为“wwe”前缀尚未定义。 这就是为什么我假设通过使用以下命名空间“检查”存在于xml中。 这对于您的xml会有所不同，但您必须相应地更改xslt命名空间部分
