Querying an XML database?

XML + Xquery + XSLT

[Darkelve]

I have an XML data source (list of sales points), e.g.

<xml>
<salespoints>
<seller>
<name>
acme
</name>
<postalcode>
123456789
</postalcode>
<address>
teertsstreet
</address>
<product>
jellyfish
</product>
</seller>
</salespoints>
</xml>

What I want to do is provide a form where the user enters his postal code, then it filters this and gets all the corresponding results from the XML datasource and presents the whole as a web page through XSLT.

How would I best go about to obtaining this result?

Also, the source file will be an Excel file. Anyone know a good way to convert an Excel file to an XML datasource, like described above?

Thanks,

Darkelve

Why not just Google for it. Type in "Excel XML". Plenty of stuff to go on.
