NSString *xmlString = @"Jack13";如 何對這個xmlString構造一個NSXML,以及如何解析構造的NSXML.

解決方法：先轉換成NSData，然後用NSXMlParser進行解析。代碼：

1. - (void)handleXMLData {
2.     NSString *myString = @"DoeJohn";
3.     NSData *myRequestData = [ NSData dataWithBytes: [myString UTF8String]  length:[myString length]];
4.     NSXMLParser *myParser = [[NSXMLParser alloc] initWithData:myRequestData];
5.     [myParser setDelegate:self];
6.     [myParser setShouldProcessNamespaces:YES];
7.     [myParser setShouldReportNamespacePrefixes:YES];
8.     [myParser setShouldResolveExternalEntities:NO];
9.     BOOL success = [myParser parse];
10.     [myParser release];
