You call -mainFrameDocument on your WebView to get a DOMDocument

headers files directly to see what function is available, for
example the DOMDocument.h file show you that there is a -
[DomDocument getElementById:] method.
Is it possible to use the DOM functions without first creating the
WebView?
I want to download a webpage and parse its contents without ever
displaying the page. I currently parse the html text directly, but
it is somewhat cumbersome. If I could just walk the DOM
structure, then that would likely be much cleaner.
No, this is not possible. But there is no reason why you have to
present the WebView to the user. Just stick it in an offscreen
window and wait for it to load.
Mike.
I don't think you have to create an offscreen window at all.
Creating the WebView and loading the URL programmatically is enough
to access the dom tree.
That would be ideal, but I could swear I've run across WebKit
documentation stating that a WebView must be placed within a window
for it to operate properly._______________________________________________
