# LuaRegexMatch Methods

A `LuaRegexMatch` object provides information about the matches for a regular expression found in a string. For example, the `regex_search` function returns a `LuaRegexMatch` object.

If a match is found for a regular expression at multiple points in the string, you can use the `next()` method to get a `LuaRegexMatch` object for the next match.

If the regular expression contained sub-expressions (surrounded by parentheses) the methods of `LuaRegexMatch` objects can also be used to retrieve information about the sub-expression matches.

If you have a `LuaRegexMatch` object called `match` you can call its methods using the "`:`" operator. For example:

    match:length()

Method | Description
--- | ---
length | Returns the length of the sub match.
next | Returns a LuaRegexMatch for the next match.
position | Returns the position of the sub match as an index from 1.
size | Returns the number of sub matches for the current match.
str | Returns the string for the sub match.
