"Many many thanks for sharing this useful tool. "Do you have any examples using the "exec" method in AS3? Trying to use it, but it's only showing the match in the textfield output one time, as opposed to the traced output. readable compact tutorials in cheatsheet style. On the next exec it will continue from there and find the second match. Trace(reg.exec(s)) //traces hello, 5, hella the "lastIndex" is where as3 halted after matching the first word in this case (hello is 5 characters long). The "/g" flag at the end renders the matching global and not just on first occurrence. "Hey Katie this is an example of the exec method in AS3. In particular, this means that character classes do not contain meta characters which need to be escaped, except the - and character, where it is assumed that a - needs not to be escaped only. "you know what? i use this for almost 2 years and running " Note: These Regexs are examples and not built for a particular Regex engine. "Can you add some posix regular expressions? especially citing where they are different as I use Oracle regexp_replace and regexp_like and not all regex references offer useful tools for this type. I have been using this for close to two years now. "Thank you very much for creating this tool. "Hi, First of all Thanks very much this is so useful.but can u suggest me proper regex for catching " "This saved me a ton of time working out a regular expression. "thank you very much.i did not know how to do negation matches.thanks to your site, I was able to figure it out using: (?!negation-string) Thanks! " (The only time this breaks is if there is a > between the two tags.) An even better solution is to use a negated character This solution is not efficient because the regex engine still searches backwards andĮxtra cpu cycles are lost. That's because the is "greedy" and searches from the end of the string backwards.Įverything from the FIRST span tag to the LAST span tag is removed. The above expression will work fine, but if you have something like: If you want to remove pairs of html tags and any text between them, you might be tempted \- the - must be escaped inside brackets: matches ( or ) (in javascript, the escape slash must be escaped!) Regular Expression Syntax: matches any one a, g, or k Code: / expression/," replacement string"Īn example that is not lavish and not in Istanbul! ![]()
