Filter XML results with select menu

[Diggum1]

I have an XML file where each coupon has a category node. For example:
<master>
<coupon>
<category>category 1</category>
<description>blah blah blah</description>
</coupon>

<coupon>
<category>category 2</category>
<description>blah blah blah</description>
</coupon>
</master>

I'd like to filter the results so that only results from a given category display. This would be in my XSL (just shows an example)

select name="filter">
<option>category 1</option>
<option>category 2</option>

<xsl:for-each select="master/coupon">
<xsl:value-of select="category"/>
<xsl:value-of select="description"/>
</xsl:for-each>


I'm not sure where to start. Is there a Javascript method to do this? How do I associate the select dropdown to the XSL?

Thanks
Rick

><xsl:for-each select="master/coupon">
[tt]<xsl:for-each select="master/coupon[category='category 1']">[/tt]
The rest, I don't understand what you're asking without seeing what you're doing.

Thanks for the response.

So how would I make that filter criteria [category='category 1'] dependent on the dropdown menu?

For example, a user selects Category 1 from the dropwdown, it should dynamically update the filter criteria in the <xsl:for-each select="master/coupon[category='category 1']"> statement and only show those results.

So, maybe [category='category 1'] could be a variable, and that variable is updated by the dropdown? I'm just not sure...

Thanks
