findRE

Syntax

findRE PATTERN INPUT [LIMIT]

By default all matches will be included. The number of matches can be limited with an optional third parameter.

The example below returns a list of all second level headers (<h2>) in the content:

{{ findRE "<h2.*?>(.|\n)*?</h2>" .Content }}

You can limit the number of matches in the list with a third parameter. The following example shows how to limit the returned value to just one match (or none, if there are no matched substrings):

{{ findRE "<h2.*?>(.|\n)*?</h2>" .Content 1 }}
    <!-- returns ["<h2 id="#foo">Foo</h2>"] -->
