Example regular expressions:
{<!--(?:.|\s)*?-->} -- Shows comments in html
- { open delimiter
- <!-- search for opening comment tag
- (?:.|\s)* any number of characters or white space
- ? non-greedy
- --> search for closing comment tag
- } close delimiter
{<style type(?:.|\s)*?</style>} -- Shows styles
Notes:
- The results page shows the individual matches and subpattern matches, and the original text with the matches highlighted.
- Might not be able to search for html entities like "&" because of the converting for display and textareas (the search pattern (regexp) and non-url subjects are processed by unhtmlentities)
