Subject: filtering XML results dynamically with select dropdown
Author: rick king

I'd like to use a select dropdown to act as a filter when displaying my XML results. I'm assuming Javascript could set the filter criteria of my XSLT depending on the selection in the select menu.

So, a user would select a category from the select dropdown, and that selection would be passed to the <xsl:for-each> statement and filter by category. Something like the following:

<xsl:for-each select="catalog/coupons[category='@cateogry']">

I'm just not sure how to do this. Is there a javascript (or maybe a VB script) that can do this?

So far, I've got the select dropdown populated with the <category> node, and I've created a parameter for category. Now I'm stuck!

Here's my MXL:

<?xml version="1.0" ?>
<catalog>
<coupons>
<title>Title</title>
<category>Category</category>
<description>Decription</description>
<coupons>
<catalog>
<coupons>
<title>Title2</title>
<category>Category2</category>
<description>Decription2</description>
<coupons>

Here's my XSLT:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">
<xsl:key name="itemType" match="catalog/coupons/category" use="."/

<xsl:param name="category"/>
<xsl:template match="/">

<script language="JavaScript">
<xsl:comment>
function setForm()
{
'hmmm...')
}
</xsl:comment>
</script>

<table width="550" cellpadding="6" >
<tr >
<td >


<xsl:element name="select" >
<xsl:attribute name="name">category</xsl:attribute>
<xsl:attribute name="onchange_">setForm()</xsl:attribute>
<option name="selected">Choose Category </option>

<xsl:for-each select="catalog/coupons/category[count(. |
key('itemType', .)[1]) = 1]">
<OPTION>
<xsl:attribute name="class"></xsl:attribute>
<xsl:value-of select="."/>
</OPTION>
</xsl:for-each>
</xsl:element>


</td>
</tr>
</table>
<table width="600" cellpadding="6" >

<tr valign="top" class="underline">
<td align="left" width="200" >Title</td>
<td align="left" width="200">Category </td>
<td align="left" width="200">Description</td>
</tr>

<xsl:for-each select="catalog/coupons[category='@cateogry']">
<tr valign="top" class="underline">
<td >
<xsl:value-of select="title"/>
</td>
<td>
<xsl:value-of select="category"/></td>
<td>
<xsl:value-of select="description"/>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>

Any help would be much appreciated!
Thanks,
Rick

A better place to ask this would be on a XSLT list, such xsl-list run
by Mulberry Technologies, or, since you're talking about VB, one of
the Microsoft newsgroups.
