Hi Mick,

It looks like to me that the mod function could be a solution to your
problem.
Something like this:

<xsl:choose>
     <xsl:when test="@lineID mod 5 = 0">
	<td>
	     <xsl:value-of select="@lineID"/>
	</td>
     </xsl:when>
     <xsl:otherwise>
	<td></td>
     </xsl:otherwise>
<xsl:choose>

Give that a shot and let me know if it works out for you.

Subject: Selectively displaying numbers


I have the following problem. In an xml file I have marked up lines, using
an attribute for line numbers, e.g.:

<line lineID="1">this is the first line</line>
<line lineID="2">this is the second line</line>
<line lineID="3">and so on, and so forth</line>

I'm using the following xsl to display the lines and their line numbers:

<td><xsl:value-of select="@lineID"/></td> <td><xsl:value-of
select="."/></td>

With this, each line is numbered. What I would like is to number ever 5th
line, so I only get line numbers for 5, 10, 15, 20 etc.

I've worked out what the xsl should be, but my knowledge of xsl-maths is
failing me. In simple prose, I would like the following. If the result of
"@lineID divided by 5" is a round number (i.e. no decimals, fractions) then
display the line number; else do not display.
In other words:

If (@lineID/5)=round number -> <td><xsl:value-of select="@lineID"/>
Else -> <td></td>

Can anyone help me and tell me what the xsl should be? Much appreciated.
