Template:Trim
From A Wiki of Ice and Fire
This template trims leading and trailing (but not interior) whitespace from a string. The string should be passed as the first unnamed parameter. The parameter must be named Template:Para if its value contains a = character.
You may substitute this template - that is, if used as {{subst:trim}}, the resulting wikicode is "clean".
Usage
[edit]{{trim|text}} = text with any leading or trailing whitespace removed.
Examples
[edit]{{trim| abc}}produces "abc"{{trim|xyz }}produces "xyz"{{trim| abc xyz }}produces "abc xyz"
