我有
"<message xmlns=\"jabber:client\" type=\"chat\" to=\"[email protected]\" from=\"[email protected]/44b97a48-f761-4332-a7a6-734e8e3d81f2\" id=\"168AA10F-B3B1-430B-9EDF-2A6126161CF5\" timestamp=\"2014-03-29 01:23:16 +0000\"><body>Yt itygvgy glkbhlkblkblkblblibibilub</body><request xmlns=\"urn:xmpp:receipts\"></request></message>"
我需要获取'to'属性的值。我用
NSArray * children = [queryElements children];
NSArray * attributes = [queryElements attributes];
NSXMLElement *qq = children[1];
NSXMLElement *resultElements = [qq elementForName: @"to" xmlns: @"jabber:client"];
NSLog(@"TWST :\n%@", resultElements);
然后获取（空）。
我通过]得到这个>
NSArray * children = [queryElements children]; NSLog(@"children:\n%@ :\n", children); NSXMLElement *qq = children[1]; NSArray * children2 = [qq children]; NSLog(@"22:\n%@ :\n", children2[0]); //body NSArray * children333 = [qq attributes]; NSLog(@"3333:\n%@ :\n", children333[2]); //from还有更聪明的方法吗？

如果要从数组中获取所有属性，则可以使用这种方式：
