Hi there. I have just studied strings and i have encountered a problem.
I have an htmlfile (.html) with some tags. Now, The specification indicates that a tag should always begin with a < on the first character of a line. It follows that if you find spaces before the '<' you should report an error. Any spaces on the right-hand side should be removed. I know i have to use the pos() function but i couldn't get heads or tails from where to start. Can some1 tell me how to do this?
