Hi Mathew,
Here is a simple xslt:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wfs="http://www.opengis.net/wfs"
xmlns:gml="http://www.opengis.net/gml"
xmlns:geo="http://www.web-demographics.com/geo"
version="1.0">
<xsl:template match="/">
<html>
<body bgcolor="#C8C8C8">
<h2>ID:
<xsl:value-of
select="wfs:FeatureCollection/gml:featureMember/geo:state/@fid" />
</h2>
<table border="1">
<tr bgcolor="#808080">
<th>State</th>
<th>State FIPS</th>
</tr>
<tr>
<td>
<xsl:value-of
select="wfs:FeatureCollection/gml:featureMember/geo:state/geo:name"/>
</td>
<td>
<xsl:value-of
select="wfs:FeatureCollection/gml:featureMember/geo:state/geo:STATE"/>
</td>
</tr>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Using this GetFeature request:
<wfs:GetFeature service="WFS" version="1.0.0"
outputFormat="GML2"
xmlns:topp="http://www.openplans.org/geo"
xmlns:wfs="http://www.opengis.net/wfs"

<wfs:Query typeName="geo:state">

Resulting in this GML:

Subject: Re: [Geoserver-users] Additional WMS GetFeatureInfo questions
Javier,
Based on what you and Chris Holmes have said, yes, I am defintely
going the WFS GetFeature route.
My plan is to write an AJAX interface that will route the WFS request
through a jsp page which will also serve as a proxy for external WFS
requests. I'll transform it to html server-side and send it back to
the browser.
Still, coming from a long history with mapserver, I am frustrated at
the amount of work it takes to simply query the data. With mapserver,
the concept of query templates are key, allowing you to create custom
html layouts that are populated by query results from the vector
attribute tables. It literally takes 3 minutes to accomplish.
Customizing my javascript to do a WFS request and transforming the GML
into HTML is a cumbersome process but apparently quite necessary.
As I am quite new to XSLT, does anyone have an example of transforming
WFS/GML into a tabular HTML layout?

Have you considered using WFS? I am using WMS to present the layers
and WFS to get the details when the user click. With WFS you will be
able to:-Set the buffer, tolerance of the click by units of measurement.
-Get the data in XML and trasnform it to any other format like HTML.
-Decide how many features you want to get when the user click and
there are several features behind a point. You can decide to get them
all, to get only one, etc...
-Decide the data, properties, that you want the server to return to you.
