It looks like you're gonna have to parse the XML and build the dictionary manually.

Look into NSXMLParser, it's quite easy to use.

can you post your code, and then we can discuss what you are doing wrong, or possibly a different approach?

If you can get your xml data in plist format it would be much easier to do.

There's really no iPhone SDK API that I'm aware of that gives you this functionality for "free", so it may actually require some real "programming" to achieve this.

use tinyxml to parse dictionary. this is a light weight c++ library..

To easily convert XML to NSDictionary, here is a little lib to do this conversion:

XML to NSDictionary Converter bcaccinolo's blog

The code is on Github.

You simply do:

NSDictionary *dic = [XMLReader dictionaryForXMLString:XML error:nil];

You get:

{
    Grandfather =     {
        Son =         (
                        {
                Grandson =                 {
                    name = 1;
                };
                name = 1;
            },
                        {
                Grandson =                 {
                    name = 1;
                };
                name = 2;
            },
                        {
                Grandson =                 (
                                        {
                        name = 1;
                    },
                                        {
                        name = 2;
                    },
                                        {
                        name = 3;
                    }
                );
                name = 3;
            }
        );
    };
}

Hey everybody...I have a problem.

I used the XMLReader class to get a NSDictionary and everything works fine. But i can't to get the values of the atributes of my productData element.

Specifically i have the following NSDictionary:


{
response = {
products = {
productsData = (
{
alias = "Product 1";
id = 01;
price = "10";
},
{
alias = "Product 2";
id = 02;
price = "20";
},
{
alias = "Product 3";
id = 03;
price = "30";
}
);
};
};
}

I used this code to create de NSDictionary:

NSDictionary *dictionary = [XMLReader dictionaryForXMLData:responseData error:&parseError];

and responseData contains:

<application><products>
<productData>
<id>01</id>
<price>10</price>
<alias>Product 1</alias>
</productData>
<productData>
<id>02</id>
<price>20</price>
<alias>Product 2</alias>
</productData>
<productData>
<id>02</id>
<price>20</price>
<alias>Product 3</alias>
</productData>
</products>
</application>

Then, i don't know how get the values of each productData like id, price and alias...

Anybody know how do it??

Thanks and please forgive my bad english !
