Check out this quick, simple way to test your regular expressions. http://220.127.116.11:8502/
Regular expressions can be used to search for patterns in long text documents or scraping a HTML file for relevant information.
But writing correct regular expressions can be a pain sometimes, you have to iterate multiple times before you catch every pattern in the text. What this app does is it boosts the speed of iteration as it gives you a visual way of testing your expression.
If the pattern is found in the text it gets highlighted.
