RE: [xsl] xsl:if / variables / fancy / confusing

["Johnathon Wright" <jw@xxxxxxxxxxxxx>]

Thanks! I was able to get everything to work properly. I ended up changing 
the XML for errors, but I had to use XML similar to that to populate the 
drop-downs that had already been selected.

If someone finds this in the archive, watch out for what I did with 
populating against previous submissions... I know that option_ids will not 
be duplicated for different attribute_ids. If that weren't the case, I would 
have had to replace the * with something else.

   <xsl:for-each select="attribute">
    <select name="attribute_{attribute_id}">
     <xsl:if test="/configuration/details/errors/error/name = 
concat('attribute_', attribute_id)">
      <xsl:attribute name="style">background-color:#FFCC00; color:red; 
font-weight:bolder;</xsl:attribute>
     </xsl:if>

     <option value="">Select a <xsl:value-of select="attribute_name" /> 
</option>
    <xsl:for-each select="option">

     <option value="{option_id}">
      <xsl:if test="/configuration/request/* = option_id">
       <xsl:attribute name="selected">TRUE</xsl:attribute>
      </xsl:if>
      <xsl:value-of select="option_name"/><xsl:if test="price_offset &gt; 
0"> - add <xsl:value-of select="format-number(price_offset, 
'$###,###,.00')" /></xsl:if></option>


    </xsl:for-each>
       </select>
   </xsl:for-each>
