  Hi peeps,
  

  
  I've got an issue with xsl that i could use some help with. I'm under the impression that using the xsl:variable element might be a way to solve the issue.
  

  
  i would like my xslt from within a <xsl:for-each> element to parse through some nodes in a xml and to set a xsl:variable element if a condition is satisfied, Such that i could do some other stuff outside the <xsl:for-each> once the for loop is over with.
  

  
  i was wondering if this would work ?
  

  
  <xsl:variable name="trial"/> <!--an empty global variable -->
  

  
  <xsl:for-each select="some nodes here">
   <xsl:if test="if some condition is satisfied among any of the nodes">
      <!-- does this refer to the global variable "trial" ? -->
      <!-- I would like to add content to the global variable ? -->
       <xsl:variable name=trial>
            <xsl:value-of select="'yes'">
        </xsl:variable>
    </xsl:if>
  </xsl:for-each>
  

  
  <!-- seems like the global trial is still empty -->
  <xsl:if test="$trial='yes'">
  ...do some stuff ...
  </xsl:if>
  

  
  as i have commented in the xsl the global variable is shadowed while inside the for loop, and is still empty once accessed outside the for loop. Is there a way i could solve this issue ? perhaps using some other xsl element ?
  

  
  Any help would be appreciated ..
  

  
  Thanks.
