请使用 xslt 从使用 one.xml 和 Two.xml 中获取answer.xml，其中 one.xml 和 Two.xml 匹配一个元素存在于两者中，即 one.xml 具有 ;67431502 与two.xml的67431502匹配得到答案.xml

 <xsl:variable name="vDoc2" select="document('')/*/my:doc2"/>

应用于提供的 XML 文档时：

<todo-lists type='array'>
    <todo-list>
        <id type='integer'>10663712</id>
        <name>Pyramid</name>
        <todo-items type='array'>
            <todo-item>
                <id type='integer'>67431502</id>
                <content>General Items that you are working on. Enter brief description
                on what you worked on.</content>
            </todo-item>
            <todo-item>
                <id type='integer'>78230534</id>
                <content>Schedule FTPExport checking on Production.</content>
            </todo-item>
            <todo-item>
                <id type='integer'>78230579</id>
                <content>Adding Smartphone and MobileHandsets Sector on DEV</content>
            </todo-item>
            <todo-item>
                <id type='integer'>78610242</id>
                <content>Adding new Sectors on DEV.</content>
            </todo-item>
        </todo-items>
    </todo-list>
</todo-lists>

生成所需的正确答案：

<todo-lists type="array">
   <todo-list>
      <id type="integer">10663712</id>
      <name>Pyramid</name>
      <todo-items type="array">
         <todo-item>
            <id type="integer">67431502</id>
            <content>General Items that you are working on. Enter brief description
                on what you worked on.</content>
         </todo-item>
         <todo-item>
            <id type="integer">78230534</id>
            <content>Schedule FTPExport checking on Production.</content>
         </todo-item>
         <todo-item>
            <id type="integer">78230579</id>
            <content>Adding Smartphone and MobileHandsets Sector on DEV</content>
         </todo-item>
         <todo-item>
            <id type="integer">78610242</id>
            <content>Adding new Sectors on DEV.</content>
         </todo-item>
      </todo-items>
   </todo-list>
</todo-lists>

说明：

1. 为了方便起见，第二个 XML 文档嵌入在样式表中。在任何实际的实现中，它将驻留在自己的文件中——这只会导致 document() 函数调用的参数被替换为特定的文件 URL。

2. 身份规则/模板“按原样”复制每个节点。

3. 身份规则由与那些 todo-item 元素匹配的单个模板覆盖，这些元素的 id 子元素的值与 id 的值相同 第二个文档中某个 time-entry 元素的子元素。

4. 对于所有此类元素，处理过程与身份模板相同，但在当前子元素之后添加了一个额外的子元素 - 这是相应 time-entry< 的 description 子元素。 /code> 来自第二个文档。

Answer 2

对于键，此样式表：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="kDescriptionById"
             match="description"
             use="../todo-item-id"/>
    <xsl:variable name="vSource2" select="document('two.xml')"/>
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="todo-item">
        <xsl:variable name="vCurrent" select="."/>
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
            <xsl:for-each select="$vSource2">
                <xsl:apply-templates
                 select="key('kDescriptionById',$vCurrent/id)"/>
            </xsl:for-each>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

输出：

<todo-lists type="array">
    <todo-list>
        <id type="integer">10663712</id>
        <name>Pyramid</name>
        <todo-items type="array">
            <todo-item>
                <id type="integer">67431502</id>
                <content>General Items that you are working on. Enter brief description                      on what you worked on.</content>
                <description>Learn Ajax,Webservices,JSON in Javascript</description>
            </todo-item>
            <todo-item>
                <id type="integer">78230534</id>
                <content>Schedule FTPExport checking on Production.</content>
                <description>For Testing purposes....Ranjeet</description>
            </todo-item>
            <todo-item>
                <id type="integer">78230579</id>
                <content>Adding Smartphone and MobileHandsets Sector on DEV</content>
            </todo-item>
            <todo-item>
                <id type="integer">78610242</id>
                <content>Adding new Sectors on DEV.</content>
            </todo-item>
        </todo-items>
    </todo-list>
</todo-lists>

注意：key() XSLT 函数针对上下文节点的文档起作用。
