+By default, `findRE` finds all matches. You can limit the number of matches with an optional LIMIT argument.
+
+{{% readfile file="/functions/_common/regular-expressions.md" %}}
+
+This example returns a slice of all second level headings (`h2` elements) within the rendered `.Content`:
+
+```go-html-template
+{{ findRE `(?s)<h2.*?>.*?</h2>` .Content }}
+```
+
+The `s` flag causes `.` to match `\n` as well, allowing us to find an `h2` element that contains newlines.
+
+To limit the number of matches to one:
+
+```go-html-template
+{{ findRE `(?s)<h2.*?>.*?</h2>` .Content 1 }}
+```
