如何在XSLT中使用帶有應用模板的鍵

Question

我正在使用XSLT和XML，我的XML格式如下。

我有以下XSLT，它使用分頁爲好，要求是它應產生的三列（「地方辦事處」 ----「城市」 -----「國家」）在此之下所有的細節都是一樣的。這裏是XSLT，當我試圖列表時，我只是被稱爲模板「Office」。

在上面的XSLT我有一個模板，通過名稱的xsl：模板匹配=「辦公室」，如果你看到有我使用「密鑰」。在下面我從上面的XSLT中獲取的代碼中，我嘗試使用apply-templates，但它不起作用，不要考慮分頁，我會照顧。

<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>

由於您所顯示的巨大代碼牆，我無法理解您的意圖。我可以解釋一下如何在正常情況下使用xsl:key來應用模板。

如果您使用的是像一個關鍵：

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

你被他們的@id收集office節點。如果您想使用密鑰應用模板，請使用key()函數。

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

其中模板將被應用到所有的節點office與所指示的@id。另一種方法（用於衆所周知的Meunchian方法）是使用密鑰將模板應用於具有給定密鑰（即分組）的單個辦公室節點。這是通過使用來實現：

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