![]() However, any of the characters in the set \. Most characters like abc123 can be used literally inside a regular expression. However, if an unnamed subpattern occurs after "Year", it would be stored in OutputVar2, not OutputVar1. For example, if "Year" is the first subpattern, OutputVarYear would be set to the matching substring, but OutputVar1 would not be changed at all (it would retain its previous value, if any). ![]() \1 is a backreference to the string that actually matched the first capturing subpattern), they are stored in the output pseudo-array only by name (not by number). The replacement string results from some processing done on the matched string. The replacement string cannot readily be specified by a regular expression replacement pattern. The following limitation does not apply to the "O" (match object) mode: Although named subpatterns are also available by their numbers during the RegEx operation itself (e.g. The Regex.Replace(String, MatchEvaluator, Int32, Int32) method is useful for replacing a regular expression match if any of the following conditions is true. Such names may consist of up to 32 alphanumeric characters and underscores. For example, the substring that matches the named subpattern (?P\d). The exception to this is named subpatterns: they are stored by name instead of number. For example, if the variable's name is Match, the substring that matches the first subpattern would be stored in Match1, the second would be stored in Match2, and so on. If any capturing subpatterns are present inside NeedleRegEx, their matches are stored in a pseudo-array whose base name is OutputVar. If the pattern is not found (that is, if the function returns 0), this variable and all array elements below are made blank. Mode 1 (default): Specify the name of the output variable in which to store the part of Haystack that matched the entire pattern. Otherwise, specify the name of the output variable in which to store specific data, depending on which of the following modes is used. ![]() If blank or omitted, no output variable will be used. ![]() If there are no options, the ")" is optional for example, )abc is equivalent to abc. For example, the pattern i)abc.*123 would turn on the case-insensitive option and search for "abc", followed by zero or more occurrences of any character, followed by "123". The pattern's options (if any) must be included at the beginning of the string followed by a close-parenthesis. The pattern to search for, which is a Perl-compatible regular expression (PCRE). FoundPos := RegExMatch(Haystack, NeedleRegEx, OutputVar, StartingPos) Parameters Haystack RegExMatch() - Syntax & Usage | AutoHotkey RegExMatch() ĭetermines whether a string contains a pattern (regular expression). ![]()
