Fortunately I could count on getting well-formed XML, and like Jens all I needed was to extract plain text, so I changed my solution to use NSXMLDocument and the crash went away.
You actually don’t need well-formed X[H]TML to use NSXMLDocument. One of the option flags to the -init method tells it to run the ‘htmltidy’ preprocessor over the input, which will correct even the gnarliest hand-written tag-soup HTML into something the XML parser can handle. It’s extremely useful for handling random web content.
