PSA: Don't start a second NSXMLParser on the same thread where another NSXMLParser is already running, or you will have a bad time.

@boredzo So all bets are off if you're using GCD and don't know the actual thread? Is NSXMLDocument safe?
Petrifying Horror ‏@boredzo 22 Aug 2014

@mjtsai You can use a serial queue, but not concurrent, for that reason. NSXMLDoc/Element: Probably the same story; haven't looked deeply.
Petrifying Horror ‏@boredzo 22 Aug 2014

@mjtsai Actually, concurrent may be fine. Not like GCD is going to call you twice at the same time on the same thread.
Michael Tsai ‏@mjtsai 22 Aug 2014

@boredzo I was thinking of long-lived objects (e.g. documents) that you call methods on.
Petrifying Horror ‏@boredzo 22 Aug 2014

@mjtsai NSXMLDocument objects should be fine. It's parsers you don't want colliding.

@boredzo Thanks for clarifying. That makes my life much easier, like it was a few hours ago. :-)
