I am working on iOS application and i want to get the namespace of a nsxmlelement.

my NSXMLElement *query has the following value in it.

<query xmlns="jabber:iq:roster" test="this is value">
<item subscription="to" name="test" jid="test@local"/>
</query>

I have used following code to get the xmlns but its not working 

         NSLog(@"%@",[query attributeStringValueForName:@"test"]);
         NSLog(@"%@",[query attributeStringValueForName:@"xmlns"]);

Value for test is printed but the value for xmlns shows null

Please let me know how to get the value of xmlns

This is because xmlns is not an attribute. xmlns is a namespace definition. You can get it with [query namespaceForPrefix:nil].stringValue.

  • Something additional when your are using XMPPFramework (I guess), have a look at the header file `NSXMLElement+XMPP.h`. It adds properties like `xmlns` and other very useful helpers when working with XML queries and stanzas. Makes code much easier to read, then working with NSXMLElement directly. – miho Feb 05 '14 at 10:01
  • Unless you're using a wrapper library, the above code should always return nil, because nil isn't a valid prefix value when using the NSXML API. Instead, you must pass an empty string. – dgatwood Sep 11 '14 at 18:42
