I am looking to add an instant web publishing feature to the weather data that I mentioned the other day. Currently I have a database that successfully takes queries in from the web and puts them into their respective fields. What I am looking to do is add a couple of fields for these web-submitted records. Is there a way to add the XML into the HTML code so that it performs the search and then enters into the fields via the web submission? Sorry if this is a little unclear.

Yes, that's unclear. What performs the search? The XML, the HTML (or something else)? What enters into the fields?

To clarify, I want there to be a section of XML code inside the HTML code on the webpage where users enter information. I want the XML code to go out to this site:

http://weather.gov/data/current_obs/KOWD.xml and retrieve Temp, General Conditions and Relative Humidity. Then I want the XML to interact with the HTML to put the retreived information into respective fields into Filemaker using the Instant Web Publishing, the same way the fields are currently coming in over the web. Where I am confused is how to do an XML search when a submit button is pushed on a webpage that can send the information into a filemaker database. Hope that helps.

I think you have to rely on CWP for this.
