Franco is right.  You could fix it by doing "a.*?href".  However, I
would change "a.*href" to "a\s+href" since you're looking for any
amount of whitespace after the "a" and before the "href".

response = '<a href="hello1.html">test1</a> - <a href="hello2.html">test2</a>'
response.scan(/<a\s+href="(.*?)"/s) do |line|
 puts line
end
