Yup. I had edge-case crashes too (fortunately reproducible one I knew the
right edge case), and spent hours tracking it down to reentrancy problems
in initWithHTML. 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.
Well, that's not entirely true, unfortunately. Although the documentation
suggests you can, NSXMLDocument -init.... will crash if the content you're
trying to feed it is sufficiently non-XML (say an ASCII text file).
We get this all the time and it's a major pain.
