Thank you, but if I had wanted to do that I could have done it myself.
My purpose in posting commented code is to explain - to people who might want to use the code - how it works, so that they can adapt it to other situations.
I anticipate that few users, if any, will want to download BBC live streams. Their on-demand streams are much more user-friendly, for example.
This code is just an illustration of how easy it can be to use a batch script to interrogate an xml file and build a download link from it. Accordingly, this code is for posting, and explaining; not necessarily for using.
