. . .I get a runtime error saying that $1 is uninitailised.

You need to use parentheses to capture the match.

$str =~ /str=([a-zA-Z]+)/

Since you mention you want everything up to the next '&' you might be better off with a regex that does what you mean:

$str =~ /str=([^&]*)/
Edit: Fixed that typo. Arien++
