Write XML file to URL in xcode

I am trying to write data to XML file in xcode.

Say the XML file resides in http://www.abcd.com/sample.xml, i want to write data into that.

sample.xml

<Candidate>
<name>John Doe</name>
</Candidate>

I want to overwrite John Doe to something else.

All i know is i can pass NSURLString the URL &开发者_如何学编程; am very new to this technology, any help will be highly appreciated.

You are going to have to parse the xml in/out. For a test scenario you can do this:

    NSString *theName = [NSString stringWithFormat:@"%@", nameField.text]; //I guess you know you should put a textfield there
    NSMutableArray *overviewInfo = [[NSMutableArray alloc] init];
    [overviewInfo addObject:theName];

    [overviewInfo writeToURL:[NSURL URLWithString:@"http://username:password@abcd.com/sample.xml"]];
    //username is your username on server
    //password is your password on server
    //example.com is the rest of the address you want to put that on

Hope that works for you.
