XtScript Function: trim, ltrim, and rtrim

Remove whitespace (or other characters) from the beginning of a string, from the end of a string, or both.

trim in XtScript is a function that will remove extra whitespaces or a serial characters sets found from the beginning and the end of a string.

The other variation is ltrim function that will remove whitespaces or a serial of characters sets from the beginning of a string and return the result.

Otherwise, if you want the process to remove whitespaces or a serial of character sets start from the end of the string, you can use rtrim function instead.

	# Trim whitespaces or sets of characters from the beginning and the end of a string
	call trim $val=...; $charlist=...

	# Trim whitespaces or sets of characters from the beginning of a string
	call ltrim $val=...; $charlist=...

	# Trim whitespaces or sets of characters from the end of a string
	call rtrim $val=...; $charlist=...

	var $noextraspace = call ltrim $val=$trimmed

	print String: |_|<b>$string</b>|_| <br/>

  	print Trimmed: |_|<b>$trimmed</b>|_|
<!--/parser:xtscript-->
</div>
- Result:
String: |_|XtScript is server side scripting for xtgem users |_|
