Your solution has two problems:

1) Injection Vulnerability

You don't escape the %s in $1 and $'. Pass them as arguments to printf instead, adding %s in the format string where necessary

2) Performance Leak

Using $' can cause other (unrelated) regexp in your program to slow down. Add (.*) to the end of the regexp and use $2 instead of $'.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
