The basic functions of the regular expression are nothing more than search and replacement. In this article, we use the regular expression matching email. The Code is as follows:

?[Copy to clipboard] View code Perl

\ B[A-Z0-9 ._%-]+ @[A-Z0-9.-]+\.[A-Z]{2,4}\ B

At this time, the regexbuddy Interface

When you click "Explain token", you can give a detailed explanation of the role of the current regular expression segment. For example, when you move the cursor to \ B and then click explain token, the help document will be activated and the word boundaries section will be automatically located.

If you want to test and verify the regular expression you just compiled, click "test" for testing. At this time, enter the text to match the test in the text box below, such as the dog@animals.com, the matching result is marked with a yellow background color. In this example, youMaybeThe matching is not correct. Why? For the answer, seeArticleEnd.

Copy and paste

Regexbuddy can copy the Regular Expression in multiple string formats. Or the regular expression just now. It can be copied as follows as needed:

?[Copy to clipboard] View code Perl

'\\B [A-Z0-9. _ %-] + @ [A-Z0-9.-] +\\. [A-Z] {2, 4}\\B'"\\B [A-Z0-9. _ %-] + @ [A-Z0-9.-] +\\. [A-Z] {2, 4}\\B"'/\\B [A-Z0-9. _ %-] + @ [A-Z0-9.-] +\\. [A-Z] {2, 4}\\B/I'

The specific options are shown in the copy menu, as shown in. You don't have to worry about single double quotes and forward and backward slashes.

Similar applications are also available in paste menu items.

• Iterate over all matches in a string. Lists All matching items in a string. (For example, when the regular expression '\ W' is used to match the string 'abc', the content listed in this function is 'A',' B ', 'C '.). The meaning of the word iterate isRepeated.
• Comment with regexbuddy's RegEx tree. Comment on the regular tree of regexbuddy.

Text split

If the text to be processed is separated by certain delimiters that can be described in regular expressions (for example, HTML tags), the split function of regexbuddy can be used to show its advantages. I opened a meal webpageSource codeIn the message section (<DivID=The text in "stream"> and </div> is processed. The following regular expression is used to delete all angle brackets and only common text is left.

The regular expression used is:
