    How to reference values from outer loop??

    Hi,
    I am working on an XSL stylesheet and I have a loop within a loop where I need to compare element values from the inside loop to values from the outer loop (see bolded line in XSL below). The inside loop references elements from a second XML document, which makes this especially difficult (at least difficult for me).
    The outermost (first) loop references elements in the Primary XML file (the one to which the XSL is applied directly) and the inner loop references elements in the Second XML file.

    Hopefully this makes sense...

    Thank you so much!!
    Christine

      Strangely enough, I had this problem 2 weeks ago. Before the for-each, create a variable pointing to your current location. Then reference that variable. In your case, you could simply make a variable pointing to the value of the Name element.

      Code:
      <xsl:if test="Real">
[B]<xsl:variable name="Name" select="Name"/>[/B]
<xsl:for-each select="$file2/RecipeElement/Parameter">
<xsl:if test="matches('Name/text()'[B],$Name)"> [/B] <td>
0
</td>
</xsl:if>
      Further simplifying, you could do this check in the for-each loop
      Code:
      <xsl:if test="Real">
<xsl:for-each select="$file2/RecipeElement/Parameter[B][Name = current()/$Name]"[/B]>
<td>
0
</td>
</xsl:if>
