Who does this work of finding, replacing, splitting? For instance, you can find regex engines in text editors such as Notepad and Edit Pad Pro.
You also find regex engines ready to roar in most programming languages—such as C#, Python, Perl, PHP, Java, Java Script and Ruby. At this stage, this is a semantic question—it depends on what one means by regular expression. When I was a young dinosaur, I didn't take the time to properly learn the syntax, largely because I really didn't feel like learning another language.
Just imagine you’re doing this before testing modifier to all the regexes to speed up the tests. Here’s a plain text list of all the URLs used in the test.
My knowledge of regular expressions is basic and doesn't allow me to choose from the hundreds of regular expressions I've already seen on the web. The URL expression recommended (and which worked great for me) is: "^(ht|f)tp(s?
If a URL has no leading "http(etc)", how would you be able to distinguish it from any other arbitrary string that happens to have dots in it? )\:\/\/[0-9a-z A-Z]([-.\w]*[0-9a-z A-Z])*(:(0-9)*)*(\/?
What's more, the raw syntax you usually see in code that contains regexes used to intimidate me. $&'\(\)\*\ ,;=]|:|@)*)*)|((([a-z]|\d|-|\.|_|~|[\x00A0-\x D7FF\x F900-\x FDCF\x FDF0-\x FFEF])|(%[\da-f])|[!

This page explains what makes this site special among all other regex sites, but first let's answer a burning question: What is the meaning of life? As per the regex humor page, it's simply matches the position in the string Camel Case where we shift from a lower-case letter to an upper-case letter.I have no interest in parsing a list of URLs from a given string of text (even though some of the regexes on this page are capable of doing that). /(((http|ftp|https):\/) (([0-9a-z_-] \.)

I also don’t want to allow every possible technically valid URL — quite the opposite. This regex tutorial, one of the most detailed on the web, takes you all the way to mastery.Typically, these patterns (which can be beautifully intricate and precise) are used for four main tasks: to find text within a larger body of text; to validate that a string conforms to a desired format; to replace text (or insert text at matched positions, which is the same process); and to split strings.but this code only can match url such as " I know this ma be a dupicate question but i have tried all of the regex provided and it does not suit my requirement. //Pattern to check if this is a valid URL address Pattern p = Pattern.compile("^( :[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9] )(? :[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9] )*(?
