I'am working on a regex str to match a expression: #acontent#url. the expression start with "#a", and the "content" can be almost things, text,num or others, then end with "#" + url.
such as there is a text content: hello, man, this is something #ayou want#http://www.stackoverflow.com.
It will be match the string "#ayou want#http://www.stackoverflow.com", I really don't konw how to write the regex.
Need some help please!
The short answer:
#a.+#((([A-Za-z]{3,9}:(?:\/\/)?)(?:[\-;:&=\+\$,\w]+@)?[A-Za-z0-9\.\-]+|(?:www\.|[\-;:&=\+\$,\w]+@)[A-Za-z0-9\.\-]+)((?:\/[\+~%\/\.\w\-_]*)?\??(?:[\-\+=&;%@\.\w_]*)#?(?:[\.\!\/\\\w]*))?)
This will match any character except line breaks in the content section, and should match any url.
NOTE: You will have to escape all backslashes in the given regex to represent it as a java String literal.

What is the best regular expression to check if a string is a valid URL?
