Как в тексте оставить ссылки вида href='#id' и удалить остальные?

Question

[pcdesign]

Например, текст:

<p>Lorem Ipsum is simply dummy text of the printing and <a href="/ggg">typesetting</a> industry.
Lorem Ipsum has been the industry's standard <a href="#id">dummy</a> text ever since the 1500s, when an
unknown printer took a galley of type and scrambled it to make a type specimen book.</p>

<p>It has survived not only five centuries, but also
 the <a href="http://example.com">leap</a> into electronic typesetting...</p>

Ожидаемый результат:

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has been the industry's standard <a href="#id">dummy</a> text ever since the 1500s, when an
unknown printer took a galley of type and scrambled it to make a type specimen book.</p>

<p>It has survived not only five centuries, but also the leap into electronic typesetting...</p>

Может есть какой-нибудь модуль, который бы умел это делать?
