• File tests/OFXMLParserTests.m — part of check-in [9d79d92d9a] at 2010-06-12 19:47:43 on branch trunk — Several OFXMLParser improvements. See details.

  * found* renamed to didFind*.
  * Support for parsing CDATA.
  * Handle comments with - correctly.
  * Don't strip leading and trailing whitespaces in comments.
  * Rename a few states for more clarity.
  * More OFXMLParser tests. (user: js, size: 9798) [annotate] [blame] [check-ins using]
