Global matching with Regex?

How can I do a global match as outlined here?

For example (simple hypothetical) if I wanted to strip all white space from part of a string:

Any help greatly appreciated.

Re: Global matching with Regex?

FROM:
"    tushar is a good      boy     "
TO:
"tushar is a good boy"

You can use the CleanUp Rule with "Fix spaces"

If you prefer RegEx:

FROM:
"    tushar is a good      boy     "
TO:
" tushar is a good boy "

You can regex search for "\s\s+" and replace by one single space.

and to get
"tushar is a good boy"
To remove leading and trailing spaces also, additionally search for "^\s+|\s+$" and replace with nothing in an second RegEx rule.

And now altogether with only one RegEx rule:

FROM:
"    tushar is a good      boy     "
TO:
"tushar is a good boy"

Search for "^\s+|\s+$|(\s)\s+" and replace with "$1"

That is  "^\s+  |  \s+$  |  (\s)\s+"

For more complex rules we would use PascalScript.
