string llStringTrim(string text, integer trim_type)

Outputs a string eliminating whitespace from the start and/or end of the specified string.

Constants for trim_type:
STRING_TRIM_HEAD: trim all leading spaces in text

In this case, whitespace can mean:

Spaces (ASCII 32)
Tabs (ASCII 9) - \t
New line (ASCII 10) - \n

To eliminate all whitespace:
Example:

llStringTrim(" Testing 1 2 3 ", STRING_TRIM);

Output:

"Testing 1 2 3"

To eliminate only the starting whitespace:
Example:

llStringTrim(" \tTesting 1 2 3 ", STRING_TRIM_HEAD);

Output:

"Testing 1 2 3 "

To eliminate only the ending whitespace:
Example:

llStringTrim(" Testing 1 2 3 \n", STRING_TRIM_TAIL);
