((?<=(?<!\?)url ?= ?)|(?<=\[)|(?<=<ref>))(http:\/\/)?(www\.)?latimes\.com
Will find and edit the italicized section if the previous text is there:
<ref>http://www.example.com</ref>url= http://example.comurl =http://example.com[http://example.comurl=example.comurl=www.example.comurl=http://www.example.com
This thing will only affect the http:// or http://www. or the www. and not the url= (or variation) or the square bracket, through the magic of Regex lookbehinds.
Negative for:
https://www.example.comand all other things containinghttps://www.orhttps://before the url- ?url=http://www.example.com
Doesn't work in Firefox, so bot will run in Chrome when approved instead :o
