每个电影或电视剧（在第一个文档中）都有一个@id属性，它与第二个文档中的Heading16元素匹配，当找到匹配时，Heading15应该插入到最终genreWrap元素之后的movie或tvShow元素中在摘要元素中。任何帮助都是非常有用的。有电影或tvShow元素具有相同的@id属性，因为它们是一个盒子集，以防万一。
编辑-------我正在使用XSLT 2.0
这是我到目前为止所尝试的内容 - 我还没有弄清楚如何将文件2的特定部分放入摘要节点。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template name="main">
<xsl:for-each-group
select="(document('File1.xml')/mediaList/*, document('File2.xml')/root/row)"
group-by="@id, Heading16">
<xsl:copy-of select="current-group()"/>
</xsl:for-each-group>
</xsl:template>
<xsl:template match="genreWrap">
<xsl:copy-of select="."/>
<summary>
</summary>
</xsl:template>
</xsl:stylesheet>
答案 0 :(得分：1)
我只是利用传入文档的XSLT 2.0 key函数功能来应用密钥，如
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:param name="doc2-url" select="'test2015020703.xml'"/>
<xsl:variable name="doc2" select="document($doc2-url)"/>
<xsl:key name="id" match="row" use="Heading16"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="genreWrap">
<xsl:next-match/>
<xsl:apply-templates select="key('id', ../@id, $doc2)/Heading15"/>
</xsl:template>
<xsl:template match="Heading15">
<summary>
<xsl:apply-templates/>
</summary>
</xsl:template>
