Question

目前它比较<title>并进行操作，我也想比较<code>&<title> 感谢

  <Types xmlns:p="foo">
   <Type>
    <title> TestingOne</title>
    <values>
        <attribute name="vala">10</attribute>
        <attribute name="codeCom">code1</attribute>
        <attribute name="valb">20</attribute>
        <attribute name="valc">30</attribute>
        <attribute name="vald">40</attribute>
    </values>
    <title> TestingTwo</title>
    <values>
        <attribute name="vala">10</attribute>
       <attribute name="codeCom">code2</attribute>
        <attribute name="valb">20</attribute>
        <attribute name="valc">15</attribute>
        <attribute name="vald">45</attribute>
    </values>
   </Type>
   <comparison>
    <comparisionList>
        <object>TestingOne</object>
        <condition>valc=30</condition>
        <code>Code1</code>
        <newName>vald</newName>
        <newValue>60</newValue>
    </comparisionList>
    <comparisionList>
        <object>TestingTwo</object>
        <condition>valb=40 or valb=20</condition>
        <code>Code2</code>
        <newName>vald</newName>
        <newValue>60</newValue>
    </comparisionList>
   </comparison>
  </Types>

目前它比较<title>并在xslt中进行操作，我也想比较<code>&<title>。我在想select="normalize-space(./preceding-sibling::[title[1] and [code])"/>之类的东西感谢

如果您在“属性”模板中包含了信息，那将会有所帮助，因为关键的是，它目前在哪里比较title元素。

看看你之前的问题，我假设这个当前的问题随之而来，“属性”模板就像这样开始......

<xsl:template match="attribute" mode="attributeCheck">
    <xsl:param name="groupName"/>
    <xsl:param name="toBeChecked" select="'default'"/>

    <xsl:variable name="testGroupName" select="$groupName"/>

    <xsl:variable name="testCondition" 
          select="normalize-space(//comparisionList/object[normalize-space(.)
                    = $testGroupName]/parent::*/condition)"/>

重新编写testCondition变量可能会有所帮助，只能获取变量中的comparisionList元素，然后可以将其重新用于获取后续的子元素。

 <xsl:variable name="testComparisionList" 
      select="//comparisionList[normalize-space(object) = $groupName]"/>

 <xsl:variable name="testCondition" 
      select="normalize-space($testComparisionList/condition)"/>

（注意，我还删除了稍微不必要的testGroupName变量，因为它与groupName变量完全相同）

所以，你需要做的是传递code并将其添加到comparisonList上的xpath条件

<xsl:template match="attribute" mode="attributeCheck">
    <xsl:param name="groupName"/>
    <xsl:param name="codeName"/>
    <xsl:param name="toBeChecked" select="'default'"/>

 <xsl:variable name="testComparisionList" 
      select="//comparisionList
                [normalize-space(object) = $groupName and normalize-space(code) = $codeName]"/>

 <xsl:variable name="testCondition" 
      select="normalize-space($testComparisionList/condition)"/>

要调用模板，您就可以执行此操作

<xsl:template match="values">
 <xsl:variable name="testName"  
  select="normalize-space(./preceding-sibling::title[1])"/>
 <xsl:variable name="testCode"  
  select="normalize-space(attribute[@name='code'])"/>
 <xsl:element name="{$testName}">
 <xsl:variable name="checkIfCondition">
  <xsl:apply-templates  select="./attribute" mode="attributeCheck">
   <xsl:with-param name="groupName" select="$testName"/>
   <xsl:with-param name="codeName" select="$testCode"/>
   <xsl:with-param name="toBeChecked" select="'shouldReplace'"/>
  </xsl:apply-templates>
 </xsl:variable>

编辑：查找comparisionList的更有效方法是定义密钥。要使用title和element查找它们，您可以像这样定义一个键

<xsl:key name="compare" 
         match="comparisionList" 
         use="concat(normalize-space(object), '|', normalize-space(code))" />

然后testComparisionList的设置如下：

 <xsl:variable name="testComparisionList" 
      select="key('compare', concat($groupName, '|', $codeName))"/>

如何比较两个xml属性
