Question

我正在使用XSLT和XML，我的XML格式低于我。

我在XSLT下面，它也使用分页，要求是它应该生成三列（“本地办公室”----“城市”-----“国家”）和所有细节在这个下面也是一样的。这是XSLT，当我试图制作列表时，我只是停止调用模板“Office”。

在上面的XSLT中，我有一个名为xsl的模板：template match =“office”，如果你看到我正在使用“Key”。在下面我从上面的XSLT中获取的代码我试图使用apply-templates，但它不起作用，不考虑分页，我会照顾。

  <xsl:when test="$city='' and $country=''">
            <xsl:choose>
              <xsl:when test="$sortby='d' or $sortby=''">
                <xsl:apply-templates select="office[@id]">
                  <xsl:sort select="$offices/office/name/." order="{$sortorder}" />
                </xsl:apply-templates>        
              </xsl:when>
              <xsl:when test="$sortby='r' or $sortby=''">
               <xsl:apply-templates select="office[@id]">
                  <xsl:sort select="$offices/office/city/." order="{$sortorder}" />
                </xsl:apply-templates>
              </xsl:when>
              <xsl:when test="$sortby='c' or $sortby=''">
                <xsl:apply-templates select="office[@id]">                
                  <xsl:sort select="$offices/office/country/." order="{$sortorder}" />
                </xsl:apply-templates>
              </xsl:when>
            </xsl:choose>
      </xsl:when>   

Answer 1

由于您展示了巨大的代码墙，我无法理解您的意图。我可以解释一下在正常情况下如何使用xsl:key来应用模板。

如果您使用的密钥如下：

 <xsl:key name="kOfficeByID" match="office" use="@id"/>

您正在通过office收集@id个节点。如果您想使用密钥应用模板，请使用key()函数。

 <xsl:apply-templates select="key('kOfficeByID',@id)"/>

其中模板将应用于具有指示的office的所有@id节点。另一种方法（在众所周知的Meunchian方法中使用）是使用密钥将模板仅应用于具有给定密钥的单个办公室节点（即分组）。这可以通过以下方式实现：

 <xsl:apply-templates select="Office[
   generate-id()
    = generate-id( key('kOfficeByID',@id)[1] )]"/>
