If it is about an #ask query with format=template, you can use 'link=none' to 
get plain strings instead of links. If you need the string to be a link again 
in other places, it's easy to add double square brackets around it again.

If you need to do that for other reasons, maybe this 
ParserFunctions/StringFunctions hack (call it Template:LinkToString or 
something) will help:

----
<noinclude>Input: A wiki-link as it comes out of #ask queries (<nowiki>[[:foo|
bar]]</nowiki>)

Output: foo</noinclude><includeonly>{{
#explode:{{#sub:{{{1}}}|3}}|{{!}}|0}}</includeonly>
----

({{!}} is the always popular pipe Template that contains nothing but '|')
