Get content between a pair of HTML tags using Bash

Question

posted Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

I need to get the HTML contents between a pair of given tags using a bash script. As an example, having the HTML code below:

<html>
<head>
</head>
<body>
 text
  <div>
  text2
    <div>
        text3
    </div>
  </div>
</body>
</html>

Using the bash command/script, given the body tag, we would get:

 text
  <div>
  text2
    <div>
    text3
    </div>
  </div>

Thanks in advance.

Using sed in shell/bash, so you needn't install something else.

tag=body
sed -n "/<$tag>/,/</$tag>/p" file
