Thanks for trying... It's a shame... I have an OPML importer (no export) working based on old code I had found based on CFXMLTreeRef, but I was hoping to write an importer/exporter based on NSXMLDocument, and this is the one sticking point - everything else has been trivial with the NSXMLDocument class. Is this just an oddity with the OPML specs, that they allow such whitespace in an attributes when XML in general doesn't? Or is it just a limitation of NSXMLNode attributes? And does this mean that there is just no way of doing it using NSXMLDocument and that I'll have to look for a different solution altogether?
Anyway, thanks for your help - much appreciated.
All the best,
Keith
