Re: Need help with count expression

I need a bit of help with count() as so far I've
been unable to construct a valid expression to obtain what  I need
Basically
what I'm trying to do is generate Table numbers relative to Chapters but only
for tables that contain a title element.  Here's an example
structure

<chapter>
    <p>...</p>
    <table
class="topic/table">
        <title class="table/title">(should
resolve to Table 1.1) ...<title>
        ...

</table>
     <table class="topic/table>...</table>

<section>
       <table> ...</table>

<table>
            <title class="table/title">(should resolve to
Table 1.2) ...<title>
            ...
        </table>
    </chapter>
<chapter>
    <table
class="topic/table>>...</table>
    <section>

<p>
            <table class="topic/table">

<title class="table/title">Should resolve to Table 2.1
</title>
                ...
            </table>

</p>
    </section>
</chapter>

Getting the
chapter number is easy enough 'count(preceding::chapter)+1' but what I'm having
problems with is the Table number in relation to the chapter
I can get the
Table position in relation to the document
via
select="count(preceding::*[contains(@class,' topic/table
')]/*[contains(@class,' topic/title ')])+1"
but I'm not quite sure how to
combine the 2 expressions to give me the proper count in relationship to the
current <chapter>

Any help would be much appreciated.

   <xsl:number count="*[contains(@class,' topic/table ')]
                      [*[contains(@class,' topic/title ')]]"
               from="chapter" level="any"/>
