For example if I have a variable x = " 10" and I would like to remove the
4 spaces before the 10 so that the variable x = "10".
Also if I again have a variable x = "10 " and I would like to remove the
4 spaces after the 10 so that the variable x = "10".

The practical solution in to use a search/replace utility such as

You then search for a regex for multiple blanks and replace with a
single blank. However that would collapse blanks inside quotes as
well.

If you want a smart one, you need to write a finite state machine to
march through all characters in the file and decide which blanks to
keep and which to discard.

You might have a look at the source code for Compactor (which
collapses blanks and blank lines for HTML)

Tabin and Tabout have more complex finite state machines, but they
ware written in C. See
