How can I loop through DOM elements? about gajavascript

[lukasberns]

You can do [myElement valueForKey:@"innerHTML"] or if you want to do it neatly, you might be able to define a protocol with a -(NSString*)innerHTML; method and cast the GAScriptObject to it. Then you can probably use myElement.innerHTML (without actually coding anything)

Apart from that I think you should ask this question on a site like StackOverflow since this is not an "issue"

In your code snippet above, [document getElementsByClassName:@"div"] would return an HTML collection of elements, so you'll have to do something like this:

#import "GAScriptMethodSignatures.h"  // for "[length]" and "[item:]"

id document = [webView documentJS];
id myElements = [document getElementsByTagName(@"div")];

for (NSInteger i = 0; i < [myElements length]; ++i)
{
    id anElement = [myElements item:i];
    NSString *innerHTML = [anElement valueForKey:@"innerHTML"];
} 

If you want to get all the DIVs filtering by an attribute, you can use [document querySelectorAll:@"div[attr=val]"]. Make sure to try out the query in the Safari Web Inspector first, since it might take some tweaks to get what you want. "querySelectorAll" is really handy and gives jQuery-like access to elements in a single method call.

Experimenting with this code helped me find a bug in the NSFastEnumeration implementation inside GAScriptObject. Cool.
