Re: [xsl] How to tell if no data returned

[George Cristian Bina <george@xxxxxxxxxxxxx>]

Hi Gary,

Just test the for-each expression after the for-each instruction and 
output whatever note you want there

<xsl:for-each="someExpression">
...
</xsl:for-each>
<xsl:if test="not(someExpression)">
  <note>someExpression does not select any nodes</note>
</xsl:if>

Best Regards,
George
