Benötigen Sie eine XSL-Lösung zu implementieren, aber ein Problem

Question

Kann nicht meine tatsächlichen Anwendungsfall zu arbeiten. Mein Code ist derzeit

<?xml version="1.0" encoding="utf-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:template name="bundle-main"> 
    <div 
     class="container" 
     data-page-type="bundle" 
     > 
     <div class="row"> 
     <xsl:for-each select="//bundles-entry-by-bundle/entry/components/item"> 
      <xsl:variable name="id" select="@id" /> 
      <xsl:if test="@section-handle = 'components-text'"> 
      <xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]"> 
       <xsl:call-template name="components-text"/> 
      </xsl:for-each> 
      </xsl:if> 
      <xsl:if test="@section-handle = 'components-link'"> 
      <xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]"> 
       <xsl:call-template name="components-link"/> 
      </xsl:for-each> 
      </xsl:if> 
     </xsl:for-each> 
     </div> 
    </div> 
    </xsl:template> 
</xsl:stylesheet> 

Das druckt eine Zeile, aber es muss die 12-Spalten-Wrapper implementieren. Mein Versuch lohnt sich nicht, da es nicht ganz funktioniert. Ich glaube, dass der Schlüsselwähler so etwas wie

sum(*[name() = concat($stack-items/@section-handle, '-entry-by-bundle')]/entry[@id = //bundles-entry-by-bundle/entry/components/item/@id]/columns/item/@handle) >= 12 or $i >= count($items) 

Hier ist der XML

Hier ist die solution würde ich mit dem obigen XML implementieren möchten und meine XSL zu ersetzen. Dieser Code

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

<xsl:template match="/root"> 
    <xsl:copy> 
     <xsl:call-template name="aggregate"> 
      <xsl:with-param name="items" select="item"/> 
     </xsl:call-template> 
    </xsl:copy> 
</xsl:template> 

<xsl:template name="aggregate"> 
    <xsl:param name="items" select="/.."/> 
    <xsl:param name="i" select="1"/> 
    <xsl:variable name="stack-items" select="$items[position() &lt;= $i]" /> 
    <xsl:choose> 
     <xsl:when test="sum($stack-items/@columns) >= 12 or $i >= count($items)"> 
      <row> 
       <xsl:copy-of select="$stack-items"/> 
      </row> 
      <xsl:if test="$i &lt; count($items)"> 
       <xsl:call-template name="aggregate"> 
        <xsl:with-param name="items" select="$items[position() > $i]"/> 
       </xsl:call-template> 
      </xsl:if> 
     </xsl:when> 
     <xsl:otherwise> 
      <xsl:call-template name="aggregate"> 
       <xsl:with-param name="items" select="$items"/> 
       <xsl:with-param name="i" select="$i + 1"/> 
      </xsl:call-template> 
     </xsl:otherwise> 
    </xsl:choose> 
</xsl:template> 

</xsl:stylesheet> 

Answer 1

ist offensichtlich falsch:

//*[concat(@section-handle,'-entry-by-bundle')] 

, weil, wenn Sie eine Zeichenfolge in einem Prädikat verwenden, der Effektivwert ist wahr, wenn die Zeichenfolge nicht leer ist, und das ist immer der Fall, hier .

Ich vermute, Sie versuchen, Elemente auszuwählen, deren Name der Verkettung von (@ section-handle, '- entry-by-bundle') entspricht. Dies scheint ein Fall zu sein, in dem Sie Vorlagenregeln anstelle von benannten Vorlagen verwenden sollten. ("Silly xsl" hat den perfekten Mechanismus für Ihre Anforderung, und Sie ignorieren es!). Ersetzen Sie diesen Code:

 <xsl:for-each select="//bundles-entry-by-bundle/entry/components/item"> 
      <xsl:variable name="id" select="@id" /> 
      <!-- silly xsl will not let us programatically call templates --> 
      <xsl:if test="@section-handle = 'components-text'"> 
      <xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]"> 
       <xsl:call-template name="components-text"/> 
      </xsl:for-each> 
      </xsl:if> 
      <xsl:if test="@section-handle = 'components-link'"> 
      <xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]"> 
       <xsl:call-template name="components-link"/> 
      </xsl:for-each> 
      </xsl:if> 
     </xsl:for-each> 

von

<xsl:for-each select="//bundles-entry-by-bundle/entry/components/item"> 
    <xsl:apply-templates select="//*[name()=concat(current()/@section-handle, '-entry-by-bundle'/> 
</xsl:template> 

<xsl:template match="component-text-entry-by-bundle"> 
    <!-- your component-text template --> 
</xsl:template> 

<xsl:template match="component-link-entry-by-bundle"> 
    <!-- your component-link template --> 
</xsl:template>
