XSL Help - Alternate row colour without being able to use position()

[Matt B]

I have a need to alternate output row colour where not every row in the
sequence is output, so I cannot base the colour on whether position() is odd
or even.
e.g.
....
<xsl:for-each select="result" >
<xsl:if test="@status = 'Pass'">
<tr><td>@name </td></tr>
</xsl:if>
<xsl:for-each>
....

Any helpful suggestions would be welcome.

Combine the if with the select then you can choose odd and even.

<xsl:for-each select="result[@status = 'Pass']">

A pure XSLT 1.0 solution:
This shows how to create a N-column table from the nodes of a node-set.
N and the node-set are passed as parameters.
No extension function is referenced (and no "following-sibling"
axis is used)
The rows are displayed in alternate colours.

Hope this helped.

You can. Something like:

<xsl:apply-templates select="result[@status='Pass']"/>

....

<xsl:template s match="result">
<tr>
<xsl:if test="position( ) mod 2 = 1">
<xsl:attribut e name="class">od d</xsl:attribute>
</xsl:templates>
<!-- something --->
</tr>
</xsl:templates>

Yes, very useful.
Thanks.

I was hoping for something which didn't rely on *all* rows having to be
output. There may be an extra selection or decision within the main
selection which means some rows aren't used. An independent toggling
solution would be very useful.

All Rows would not be passed to output using the solution by Johannes

<xsl:apply-templates select="result[@status='Pass']"/>

....

<xsl:template s match="result[@status='Pass']"/>
<tr>
<xsl:if test="position( ) mod 2 = 1">
<xsl:attribut e name="class">od d</xsl:attribute>
</xsl:templates>
<!-- something --->
</tr>
</xsl:templates>

Is the problem due to the non pass nodes being processed by the default template. If so add a bit bucket template eg

<xsl:apply-templates select="result"/>

If this is the case result nodes with a status of pass will be processed into the output tree by Johannes template . Non pass nodes will hit the bit bucket and not pass through.

If you mean something else could you give some test XML and an example of your target output.

You appear to be insisting on having an if within a for-each but this is carried out by the predicate [@status='Pass'] don't forget you can use multiple predicates by joining with and's and or's so any extra selection or decision can be made within the select statement. Also nodesets can be passed around with variables. Give some examples of what you need.

I just noticed that in Johannes template the apply-templates does not implicitly tie in with the template. In the posting above notice how the predicate is applied to the apply-template select and the the template match clauses. Another way is to tie the two together by using mode.
