## findRESubmatch
In Hugo 0.110.0 we added a variant of `findRe` that returns a slice of strings holding the text of the leftmost match of the regular expression in s and the matches, if any, of its subexpressions.
This:
```go-html-template
{{ findRESubmatch §§<a\s*href="(.+?)">(.+?)</a>§§ §§<li><a href="#foo">Foo</a></li> <li><a href="#bar">Bar</a></li>§§ | print | safeHTML }}
```
Will print:
```
[[<a href=\"#foo\">Foo</a> #foo Foo] [<a href=\"#bar\">Bar</a> #bar Bar]]
```
