// XML Parsing

 

NSString * str = [NSString stringWithContentsOfFile: [[NSBundle mainBundle] pathForResource: @ "Students" ofType: @ "txt"] encoding: NSUTF8StringEncoding error: nil];

 

// Parse XML and put the result in the document

GDataXMLDocument * document = [[GDataXMLDocument alloc] initWithXMLString: str options: 0 error: nil];

GDataXMLElement * root = [document rootElement]; // obtain the root node

 

NSArray * arr = [root nodesForXPath: @ "// name" error: nil];

// Traverse nodes

For (GDataXMLElement * name in arr)

{

}

// Json Parsing
