I used:
<xtags:variable id="total"
select="count(//item[title=$Criteria])"/>
The total is <%= total %>
---
However, "The total is 1.0" is displayed. I did not expect a
decimal display for a count value. Is this something that can be
changed in xtags?
To work around this, I went back to the forEach loop.
<xtags:forEach select="//item">
<xtags:if test="./title=$Criteria">
<% totalcount++; %>
</xtags:if>
</xtags:forEach>
It's not as pretty, but it works.
