Thank you for your help on this matter.
I need this entire process to be quick,
- processing the file
- downloading the xml file.
As you've mentioned the XMLDocument will load the entire document into the
memory (which probably means that the XML file will first have to be
downloaded from the site), which could take some time.
But i'll give this a go,
Once again, thanks.
