This template is for trimming whitespace from strings. For the maintenance tag for images, see {{ trimming }}
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 |1= if its value contains a = character.
You may substitute this template - that is, if used as {{subst:trim }}, the resulting wikicode is "clean".
{{trim |text }} = text with any leading or trailing whitespace removed.
"{{trim |abc}}" produces "abc"
"{{trim |xyz }}" produces "xyz"
"{{trim |abc xyz }}" produces "abc xyz" Template parameters
