log(regex.test(string)); // 输出: true // 使用match方法获取所有匹配的结果 console.log(string.match(regex)); // 输出: [ '123', '456', '789' ] 在上述示例中,正则表达式/\d+/g匹配了字符串'abc123def456ghi789'中的所有数字,并使用match方法返回了一个包含所有匹配结果的数组['123'...

TRE is completely thread safe. All the exported functions are re-entrant, and a single compiled regexp object can be used simultaneously in multiple contexts; e.g. inmain()and a signal handler, or in many threads of a multithreaded application. ...
group(0) # The entire match 'Isaac Newton' >>> m.group(1) # The first parenthesized subgroup. 'Isaac' >>> m.group(2) # The second parenthesized subgroup. 'Newton' >>> m.group(1, 2) # Multiple arguments give us a tuple. ('Isaac', 'Newton') 如果正则表达式使用了 (?P<name>…...
将正则表达式的样式编译为一个正则表达式对象(正则对象),可以用于匹配,通过这个对象的方法match(),search()以及其他如下描述。 这个表达式的行为可以通过指定标记的值来改变。值可以是以下任意变量,可以通过位的OR操作来结合(|操作符)。 序列 prog=re.compile(pattern)result=prog.match(string) ...
