ok, this seems mighty round about, but this works.... let me know
if you think there is a simpler way... i found atleast two sets of
documentation on this from "developer/Apple" on DomNodes or
DOMObjects neither had the same info... but combining the two, i
think i figured it out...
DOMDocument *myDOMDocument = [[myWebView mainFrame] DOMDocument];
DOMNodeList *allParas = [myDOMDocument getElementsByTagName:@"p"];
DOMNode *node = [allParas item:0];
DOMNodeList *nodeList = [node childNodes];
DOMHTMLLinkElement* link = (DOMHTMLLinkElement*)[nodeList
item:1];
NSString* href = [link href];
NSString *top = [node textContent];
now href conatins a string with the link in it, and top contains the
rest of the text within the "paragraph"...
this is the paragraph example again:
<p> Aug 19 - <a href="http://whatever/sys/1331140637.html";>Two 1GB
Apple matched pair RAM from a MacBook - $30 -</a><font size="-1">

I have found that there is extremely limited documentation dealing
with DOMNodeLists and DOMNode...
for instance i found by pure accident that textContent works on a
node, and found no documentation on it... and lots references to
getAttribute or getElementID but can not get them to work...
so here is what i'm trying to do with code and maybe someone has
figured this out...
thanks in advance..
here is some data in some HTML that I would like to parse, i've
found how to get the text out, but i can't get this URL out....

here is the code i'm using to parse it.... most of it works,
including the textContent, last two lines don't work...trying to
get this "http://whatever/sys/1331140637.html"; into a NSString, or
NSURL is failing me...
DOMDocument *myDOMDocument = [[myWebView mainFrame] DOMDocument];
DOMNodeList *allParas = [myDOMDocument getElementsByTagName:@"p"];
DOMNode *node = [allParas item:0];
NSString *top = [node textContent];
NSString *top2 = [node getAttribute:@"href"]; // this is way
off, just trying to find methods, but i expected getAttribute to
atleast be acknowledged as a method????
NSString *top4 = [node getElementById:@"href"]; // this is way
off, but i expected getElementById to atleast be acknowledged as a
method????
any help would be great...
thanks,
Jon.
