Hi Gary,

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

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

Hi all

I have a problem which I would normally fix using a variable. I have a
routine similar to that below. What I want to know is if it doesnt get into
the for-each loop. If it doesnt it means no rows are written and I would
like to add a note to the page if this is the case.

Any suggestions how I might do this.


<xsl:for-each select="/stages/competition/leg/stage/classification/competitor[../../@no=$s Num]"> <xsl:if test="../@type = 'STAGE'"> <xsl:if test="../../../../@cno=$paramVal1">

... row detail written here
