is there call can find "teamname" , extract teamname between > <.

i go char char saving last 10 chars string until string equals "teamname", keep going until hit > save until again hit <. guess thats taking easy inefficient way.

many -code

you can range of string "class" using nsrange, logic... reduce character searching..

your code should follows,

if ([substring rangeofstring:@"class"].location != nsnotfound) {     // "class" found else {     // "class" not found }
