Question

我的XSLT低于单一分组，但是我需要为我的xml进行多次分组：

XSLT1.0：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:strip-space elements="*"/>
  <xsl:output indent="yes"/>
  <xsl:variable name="linkURL" select="'/system/ASPX/Link.aspx?ID='"/>
  <xsl:template match="*">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates select="node()"/>
      <xsl:if test="self::navigation">
        <node GroupTitle="{//@GroupTitle[1]}" GroupCode="{//@GroupCode[1]}" url="{$linkURL}{//@GroupID[1]}">
          <nodes>
            <xsl:apply-templates select="node()" mode="group"></xsl:apply-templates>
          </nodes>
        </node>        
      </xsl:if>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[normalize-space(@GroupCode) and not(*[not(normalize-space(@GroupCode))])]"/>

  <xsl:template match="node[normalize-space(@GroupCode)]" mode="group">
    <xsl:copy>    
      <xsl:apply-templates select="@*" mode="group"/>   
      <xsl:apply-templates select="node()" mode="group"/>      
    </xsl:copy>
  </xsl:template>

  <xsl:template match="node" mode="group">     
    <xsl:apply-templates select="node()" mode="group"/>
  </xsl:template>

  <xsl:template match="*" mode="group"/>

  <xsl:template  match="@*" mode="group">
    <xsl:attribute name="{name()}">
      <xsl:value-of select="."/>
    </xsl:attribute>
  </xsl:template>
  <!-- node attributes to be deleted have an empty template each -->
  <xsl:template match="@GroupTitle" mode="group"/>
  <xsl:template match="@GroupCode" mode="group"/>
  <xsl:template match="@GroupID" mode="group"/>
</xsl:stylesheet>

XML的一部分：

<?xml version="1.0" encoding="utf-16"?>

        </node>
    </node>
</navigation>

在上面的xml中你会发现有两种类型的 GroupCode =“PB”和 GroupCode =“SB”，上面的XSLT代码只进行了一次分组，但是xml中可以有很多GroupCode，根据我的分组将完成。对于上面的部分XML，我看下面的输出：

Answer 1

我使用以下更改修改了我的上述代码，似乎它对我有用，请建议是否需要进行任何更改。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:strip-space elements="*"/>
  <xsl:output indent="yes"/>
  <xsl:variable name="linkURL" select="'/system/ASPX/Link.aspx?ID='"/>
  <xsl:key name="nodesByGroupsCode" match="*[node[not(@GroupCode)]]" use="@GroupCode" />
  <xsl:template match="*">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates select="node()"/>
      <xsl:if test="self::navigation">
      <xsl:for-each select="//node[generate-id() = generate-id(key('nodesByGroupsCode', @GroupCode)[1])]">       
        <node GroupTitle="{@GroupTitle}" GroupCode="{@GroupCode}" Url="{$linkURL}{@GroupID}">       
          <nodes>    
           <xsl:for-each select="key('nodesByGroupsCode', @GroupCode)"> 
          <xsl:copy> 
           <xsl:apply-templates select="@*" mode="group"/>         
             <xsl:apply-templates select="node()" mode="group"></xsl:apply-templates>       
           </xsl:copy>      
            </xsl:for-each>
          </nodes>            
        </node>    
        </xsl:for-each>    
      </xsl:if>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[normalize-space(@GroupCode) and not(*[not(normalize-space(@GroupCode))])]"/>

  <xsl:template match="node[normalize-space(@GroupCode)]" mode="group">    
    <xsl:copy>         
      <xsl:apply-templates select="@*" mode="group"/>      
    </xsl:copy>       
  </xsl:template>

  <xsl:template match="*" mode="group"/>

  <xsl:template  match="@*" mode="group">
    <xsl:attribute name="{name()}">

    </xsl:attribute>
  </xsl:template>

  <!-- node attributes to be deleted have an empty template each -->
  <xsl:template match="@GroupTitle" mode="group"/>
  <xsl:template match="@GroupCode" mode="group"/>
  <xsl:template match="@GroupID" mode="group"/>

</xsl:stylesheet>

Answer 2

以上是上述问题的完整解决方案。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:variable name="linkURL" select="'/system/ASPX/Link.aspx?ID='"/>

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

     <!-- Key for Group Code attributes -->
    <xsl:key name="node" match="node" use="@GroupCode"/>

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

            <!-- use muenchian for that -->
            <xsl:if test="self::navigation">
                <xsl:for-each select="node/node[generate-id() = generate-id(key('node', @GroupCode)[1])]">
                    <xsl:variable name="this-group-code" select="@GroupCode"/>
                    <node GroupTitle="{@GroupTitle}" GroupCode="{@GroupCode}" Url="{$linkURL}{@GroupID}">
                        <nodes>
                            <!-- push out all the nodes that have this particular group code -->
                            <xsl:apply-templates select="ancestor::navigation/node/node[@GroupCode = $this-group-code]" mode="group"></xsl:apply-templates>
                        </nodes>
                    </node>
                </xsl:for-each>
            </xsl:if>
        </xsl:copy>
    </xsl:template>

    <!-- this template deletes all node that have a group code and no children that don't have a group code -->
    <xsl:template match="*[normalize-space(@GroupCode) and not(*[not(normalize-space(@GroupCode))])]"/>

    <!-- in mode group: copy all node that have a group code-->
    <xsl:template match="node[normalize-space(@GroupCode)]" mode="group">
        <xsl:copy>
            <xsl:apply-templates select="@*" mode="group"/>
            <xsl:apply-templates select="node()" mode="group"/>
        </xsl:copy>            
    </xsl:template>

    <xsl:template match="node" mode="group">
        <xsl:apply-templates select="node()" mode="group"/>
    </xsl:template>

    <!-- group mode: remove all other elements (not specified in higher up templates) -->
    <xsl:template match="*" mode="group"/>

    <!-- in mode group, copy all attributes (except those that have a more specific template match with other instructions -->
    <xsl:template  match="@*" mode="group">
        <xsl:attribute name="{name()}">
            <xsl:value-of select="."/>
        </xsl:attribute>
    </xsl:template>

    <!-- node attributes to be deleted have an empty template each -->
    <xsl:template match="@GroupTitle" mode="group"/>
    <xsl:template match="@GroupCode" mode="group"/>
    <xsl:template match="@GroupID" mode="group"/>
</xsl:stylesheet>
