XML issues

On my XPath research, I found XQuery, just what I need I thought, great, I will be able to query my xmlBank and get my results filtered with ease, digging a bit deeper, the examples shown everywhere look promising, so sleeves up, lets try it... (seconds later) ...humm, right, hummm, where do I put the XQuery code? What sort of file? Right... It seams everyone out there shows you XQuery code like:

for $x in doc("books.xml")/bookstore/book where $x/price>30 order by $x/title return $x/title

But no one tells you where to put it, or, on which file type; asp, xhtml or what?

Help please.

Client side xhtml?

I'm new to that, how do I run the code then?

Thanks.

try Response.Write(chr(13)) for a new line

Mart, yes, I tried using that code on a .xhtml, .shtml and all the rest of it, no avail, must be missing something, will look futher.

Phat, thanks, but it won't work, to create a new node I use:

Set PostElement = xmlData.createElement("Post")
PostElement.setAttribute "Title", "Some title"
PostElement.setAttribute "Author", "Ruan"
PostElement.setAttribute "Message", "Oh yeah baby."

Call xmlData.documentElement.insertBefore(PostElement, xmlData.documentElement.childNodes.item(0))

This creates an XML node like:

<Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/>

The problem is that, as I add more nodes, they will get all like this:

<Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/><Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/><Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/>

As opposed to:

<Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/>
<Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/>
<Post Title="Some title" Author="Ruan" Message="Oh yeah baby."/>

What could it be?
