我有以下这些HTML，我想删除额外的空格，需要结果如下：

<ul class="c2">
    <li><a href="hire-project-manager/">Hire Project Manager</a></li>
    <li><a href="hire-ios-developer/">Hire iPhone Developer</a></li>
    <li><a href="hire-ios-developer/">Hire iPad Developer</a></li>
    <li><a href="hire-android-developer/">Hire Android Developer</a></li>
    </li>
    <li><a href="hire-3d-artist/">Hire 3D Artist</a></li>
</ul>
</div>
<h1>Get In Touch With Us</h1>
<div class="copyright-footer">Copyright &copy; All rights reserved</div>

任何人都可以借助PHP和preg，str_replace等帮助我解决这个问题
