Parsing an XML file for a particular element, reading the children, and getting database values

[Luis Esteban Valencia]

Hi experts

What I'd like it is something like this...

I have an xml file and when going to the page, I want the page to look at
the paramater passed in with the URL and gets the XML "element" (is that the
term, it is in JDOM...)

<whatever thefieldtomatch URL="12345" dbtable="table1 ">
<db field="field1"/>
<db field="field9"/>
<db field="field3"/>
</whatever>
<whatever thefieldtomatch URL="91535" dbtable="table2 ">
<db field="field2"/>
<db field="field7"/>
<db field="field8"/>
</whatever>

thefieldtomatch URL is passed as a paramater
I need to
1. get the parameter pass it with the url (and how do I pass in a parameter
with the url?)
2. parse the xml till I get the element thefieldtomatch URL=parameter passed
in

then
go through all the children, get the value of "field" and then with that
read a value in a database from the table set in "dbtable"
the fields are used to do some calculations and result displayed on page

I'll try and explain things more on request.

I'm trying to do things well out of my scope so that's why I'm asking the
Experts! Please don't make any assumations that I know much, I'm new to
asp.net and more a Java man :-)

thanks
