[xsl] Testing for certain combinations

["Neil Abraham" <mylists at neilabraham dot co dot uk>]

Hi all,

I need a way of testing whether or not I have 3 or more <a> links separated
only by <br/> tags within a <p>.  This is hard to explain so here are some
examples:


This should test positive:

<p>
<a href="urlwhatever">Labelwhatever</a><br/>
<a href="urlwhatever">Labelwhatever</a><br/>
<a href="urlwhatever">Labelwhatever</a><br/>
</p>


This should test negative since there are only 2 links:

<p>
<a href="urlwhatever">Labelwhatever</a><br/>
<a href="urlwhatever">Labelwhatever</a><br/>
</p>


This should also test negative since it contains text outside of <a>:

<p>
See our great <a href="urlwhatever">products</a> or read
<a href="urlwhatever">about us</a>. Feel free to
<a href="urlwhatever">contact us</a> any time.
</p>


For those interested, I'm developing a stylesheet to transform our XML into
WML for UP browsers.  The UP browser (eg Siemens and Motorola phones)
displays option lists better than link lists.  Eg:

<select>
<option onpick="urlwhatever">Labelwhatever</option>
<option onpick="urlwhatever">Labelwhatever</option>
<option onpick="urlwhatever">Labelwhatever</option>
</select>


Thanks in advance for any help you can give me,

Neil.
