Hi Chrisantha,

> I have a list of strings representing numbers, i.e. a = 
> {"12223","11313","2424"} that I generated in XML and read

The easiest way is ToExpression, whence

	l = {"12223", "11313", "2424"}
	i = ToExpression@l

You can convince yourself that it works via

	Head@First@l
	Head@First@i

This will fail if your strings are in exponential format (it's easy to see
why!)

Regards,

Dave.
