Editor to share with you how to use regular expressions in go language, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

The library regexp used in regular expression processing uses regexp library functions like MustCompile and CompileMustCompile to compile regular expressions into a regular object (using PERL syntax), just like Compile. The regular object is in "leftmost-first" mode. Select the first matching result. If the regular expression syntax is incorrect, an error message is returned. The difference is that when the regular expression str is illegal, MustCompile throws an exception, while Compile returns only an error value FindString returns a string that matches the leftmost regular expression If there is no match, an empty string will be returned to practice example 1 to get the company (company name), address (address), telephone (telephone) in the following text. 78 Ejiao Street, Dong'e County, Shandong Province, 0635-3262315.
