In that case, i'll take the opportunity to mention that it needs to be done as a CGI so it's accessible as a web interface. There are custom perl modules which need to be used, which are part of the DNRS system.

The XML parsed has to conform to the DTD provided as part of this system.

The response received from the remote server is a formatted XML response which needs to be usable in regards to reformatting it for HTML layout / output to the website.

So basically, someone enters something in to a form, which gets sent off using a set of perl modules. The script then needs to capture the response and output it to the website.

I have a command line version of the interface available to see, but it needs to be altered to work as a web page.

I'm not making this stuff up! This is really what I need to do!
