Get characters from string - Arduino

Question

I have the following string:

String msg = "t22h58m798s2";

Than I created some variables:

int temperature;
int humidity;
int moisture;
int state;

I need to set value of temperature to two numbers after t character in msg. The same for other variables. Finally temperature should be 22, humidity - 58, moisture - 798 and state - 2. I receive msg from other Arduino's sensor values. I think I should do it using indexOf and charAt method, but I'm not sure how. Please hep me.

You can use substring function in arduino to a string from a particular character to another one. Like in this particular case you can use something like String temperature= msg.substring("1, 3");

Refer this for more information. http://arduino.cc/en/Tutorial/StringSubstring
