You can check with regular expressions if the string conforms to "\d+". If it does, then it is an integer.
But you need to tell us more. Do you also need to check for negative integers?
Is the integer length limited to10 chars?
Do you need to trim white spaces before/after the integer away?
If all yes, you can check with the regEx "\s*[+-]?\d{1,10}\s*".
