Try it with just the first line in the [calcn] (without the regexp and 
the $1).  That will tell you if it's the get_url that's failing or the 
regexp.

You only have to escape the / if the regexp is bounded by /.  That's why 
I used ! to bound the regexp.

You may not be able to run it from the calc block, try this:

[tmp result][get_url http://www.example.com/mypage.xml][/tmp]
[calcn]
	$Scratch->{result} =~ m!<string>(.+?)</string>!;
	$1;
[/calcn]
