Question

hello I have a NSMutableArray iconlocarr. I also have another array containing dictionary data called xmlnodes which looks like this:

{
    nodeChildArray = (
        {
            nodeContent = "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0004_black_low_cloud.png";
        }
    );
    nodeName = weatherIconUrl;
}

I am trying to add the nodeContent data (icon url) into my iconlocarr array:

[iconlocarr addObject:[[[xmlnodes objectAtIndex:i] objectForKey:@"nodeChildArray"] valueForKey:@"nodeContent"]];

The problem I have is that the above code adds the following data:

(
    {
        nodeContent = "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0004_black_low_cloud.png";
    }
)

As well the data I actually want

"http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0004_black_low_cloud.png"

How do I just add the nodeContents data and not the rest? The intention is to pass the data to a NSURL

Try this instead:

iconlocarr addObject:[[[[xmlnodes objectAtIndex:i] objectForKey:@"nodeChildArray"] objectAtIndex:0] objectForKey:@"nodeContent"]];

which consider object “nodeChildArray” as an array, then extract index 0 and then the returned dictionary will contain the “nodeContent”.
