Grouping also enables capturing. Using parentheses, you can capture and refer to the matched substring later. For example, consider the pattern: /(ab)+c/. In this pattern, the group (ab) is captured. If the string “ababc” matches this pattern, you can access the captured group and ret...
It does not capture groups from this pattern. It just sees if the pattern exists in a valid form in the input string. Note IsMatch returns a bool value. Both overloads receive an input string that is searched for matches. return bool Note 2 When we use the static Regex.IsMatch method...
NSInteger portInteger = [[searchString stringByMatching:regexString capture:1L] integerValue]; NSLog(@”portInteger: ‘%ld’”, (long)portInteger); // 2008-10-15 08:52:52.500 host_port[8021:807] portInteger: ‘8080′ 取string中http的例子。
