I'm trying to generate html code for "Date 1 of 2", "Date 2 of 2", etc., from
XML as below:

<a>
   <b/>
   <c/>
   <date>text</date>
   <date>text again</date>
</a>

from within a template that matches "d".

What is key is those nodes that are being "pushed" using <xsl:apply-templates/>


The following stylesheet fragment:

<xsl:template match="d">
  <xsl:value-of select="position()" />
  <xsl:text> of </xsl:text>
  <xsl:value-of select="count(../date)" />
</xsl:template>

produces "3 of 2" and "4 of 2".  Is there a way to restrict position() to
evaluate the <date> nodes only?

Yes, by restricting the processing to only push the date elements ... you would have something along the lines of the following in the processing of <a> in your example:


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

How else could it be done?

Independently of using position(), by counting the given elements:


<xsl:number/>

... in which case it doesn't matter what nodes are being pushed because you aren't using position(). The above instruction will count the current node amongst like sibling nodes.

I hope this helps.
