Re: A question on optimization

an xslt stylesheet is an xml document so you can transform it using
various methods, not least another xslt stylesheet. The details depend
on which API you are using.

It's unlikely to make any real difference on performace though.
Time is far more likely to be spent on navigating the tree as a whole
rather than on the fine details of the instructions used to generate a
small local result fragment.

  <xsl:for-each select="//justus:choice">
    <xsl:element name="TR">
      <xsl:variable name="current" select="."/>
      <xsl:for-each select="//justus:part[@visible='true']">
        <xsl:variable name="dbfeld" select="."/>
        <xsl:element name="td">
          <xsl:for-each
             select="$current/@*[name()=$dbfeld/@dbfeld]">
            <xsl:value-of select="."/>
          </xsl:for-each>
        </xsl:element>
      </xsl:for-each>
    </xsl:element>
  </xsl:for-each>

   <xsl:for-each select="//justus:choice">
     <xsl:element name="tr">
       <xsl:element name="td"><xsl:value-of select="a1"/></xsl:element>
       <xsl:element name="td"><xsl:value-of select="a2"/></xsl:element>
       ...
     </xsl:element>
   </xsl:for-each>
