I like to improve readability and managing some HTML source code like this
That's it:
<iframe
src = "
https://www.google.com/recaptcha/api2/anchor
? k = 6LeaOiITAAAAAF_A-e9qjM6TCgdt4-rqixnkkatL
& co = aHR0cDovL3BsYXkuc3BvdGlmeS5jb20
& hl = de
& v = r20160802154045
& theme = dark
& size = normal
& cb = ap65yyq41qhy
"
></iframe>
Well the secret ingredient here is to use solidly tab's instead of space when you are inside some string! The parser will filter them out and you get some working url.
