Well, you can ask CFXMLCreateStringByUnescapingEntities() to do this on OS X, although if I recall all the CFXML functions have now sadly been deprecated. The source code for it should still be available if you search around. But in general, I would just work my way through the string looking for occurrences of '&' and see if that makes up a valid escape sequence. Much of the problem if dealing with HTML rather than XML is that there are a vast range of special sequences. e.g. µ _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
