Regexp - (Flag|Modifier)
About
Flag or modifier changes the behavior of the parsing and therefore of the match.
List
dotall / g
A dot may matches new line or not. You specify it by specifying a flag.
Java Example with the DOTALL flag:
- A pattern that capture the content between two XML nodes even if there is new line in there.
Pattern pattern = Pattern.compile("<top>(.*?)</top>",Pattern.DOTALL);
i
the i flag will perform a case insensitive match.
Disable
If you don't have access to the regular expression compiler, you may be able to disable a flag in the regular expression with the following syntax
(?-flag)expression
To disable the multi-line flag (m), you would type:
(?-m)expression
