1. Introduction:Java. util. RegEx is a class library package that uses regular expressions to customize the pattern to match strings.
It includes two classes: Pattern and matcher pattern. A pattern is the expression mode after a regular expression is compiled.Matcher A matcher object is a state machine. It checks the string based on the pattern object as the matching mode. First, a pattern instance customiz
Recently, I want to use nekohtml to parse HTML in the project. But I have read that nekohtml is a little complicated, so I adopted a convenient and stupid method to meet the project's requirements. at this time, the regular expression played a huge role in her power. It helped me solve the problem and quickly completed HTML parsing. during the parsing, I have studied many Java Regular Expression usage methods. I have gained some experience and do not dare to share it with you. java Regular Expre

By default, these two expressions only match the start and end of the string.Pattern. UNICODE_CASE(?

By default, case-insensitive matching applies only to the US-ASCII character set.Pattern. UNIX_LINES (? D) In this mode, only 'n' is co

The Java Matcher class has a lot of useful methods. I'll cover the core methods of the Java Matcher cl
Java regular expressions match multiple rowsBy default.. only characters other than \ n can be matched. If the string to be matched contains the carriage return line break (multiple lines), the regular expression stops when it encounters a line break, as a result, the string containing the carriage return linefeed cannot be correctly matched. The solution is as follows:
1. Use Pattern and Matcher object
Set the Pattern mode:Pattern. DOTALL
2. Use Stri
