欢迎使用sed和grep的正则表达式。

Answer 1

awk '/<div class="clear"><\/div>/{p=0} p{print} /<div class="results-count">/{p=1}'

Answer 2

通过grep，

$ grep -ozP '(?s)(?:\n|^)\s*<div class="results-count">[^\n]*\n\K.*?(?=\n\s*<div class="clear"></div>)' file
<div class="AA">
  <div class="A"><a href="/TEST">BBB</a>
  </div>
  <div class="BB"><span>CCC</span><br/><a href="/TEST1" class="B">DDD</a>
    <div></div><span>EEE</span><br/><img src="TEST2" title="C"/><a href="/TEST3" class="D">FFF</a>,
<a href="/TEST4" class="E">GGG</a>
