The xpath library included with Flash 8 is really quite basic, as it is the bare minimum for generated paths for databinding purposes. It only permits abbreviated syntax (though this is fine and preferable most of the time), doesn't support any axes other than "child" (e.g. you can't do a//b or a/../c), and only supports position filtering in predicates. (e.g. you can do x/y[1], but you can't do x/y[last()]).
XFactorStudio's XPath is complete (or at least I haven't found anything that wasn't supported). If you need XPath for an AS3 (or Flex 2/3) project, I have written a library, xpath-as3, which is also a complete implementation. http://code.google.com/p/xpath-as3 Peter On 7/24/07, David Ngo <[EMAIL PROTECTED]> wrote:
Correct, but for most parsing functionality, the ones included in Flash 8 should be sufficient. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Merrill, Jason Sent: Tuesday, July 24, 2007 2:00 PM To: [email protected] Subject: RE: [Flashcoders] CDATA Html Text not working But only a partial one, right? That's what I understood - others have commented on it. I have used xfactorstudios Xpath classes instead. AS3 takes care of it though if you can go that route.
