RE: [xsl] chekcing attribute existance from a string

["Michael Kay" <mike@xxxxxxxxxxxx>]

Given that you have a list of all the attribute names, your logic should be
something like:

<xsl:for-each select="$possibleAttributes">
  <td>
  <xsl:choose>
    <xsl:when test="row/@*[name()=current()]">
       <xsl:value-of select="row/@*[name()=current()]"/>
    </xsl:when>
    <xsl:otherwise>
       <xsl:text>(blank)</xsl:text>
