October 23, 201312 yr Hi all, My latest pet project is to catch up on the subject of regular expressions but in a HTML5 context. I know that the pattern attribute for HTML5 uses Javascript Regex expressions but I've often found myself mystified by patterns i've tried to make that just don't work. I made a page on my website in which I put various expressions together for me to test which is helping me to learn how they work. I'm in the middle of writing a blog post that gives examples of expressions and search for them as well as something that explains what all the characters mean. I don't think there's a lot of support in the all the numerous searches i've done on the web. For example. I'm trying to find a regular expression to search for text input that contains a certain string of text. e.g. Dog in the dog chased his tail but I can't for the life of me figure out an expression or search for one online. Does anyone have the holy grail for that?
