如何使用sed删除html标记

输入为：

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

我尝试了sed-n的//].*>//gp'example.html 但在屏幕上什么也看不到，似乎正则表达式不正确

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

sed -n 's/<[^>]*>//gp' test.csv | sed '/^$/d'

你就快到了，小点。您使用的可以匹配>字符，因此将其从命令中删除

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

pipe后面的命令是清除所有空行，如果您的版本支持PCRE的-p选项，grep应该足够了

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

$ grep -oP '(?<=>)(.[^<]+)(?=<)' file
This is heading 1
This is heading 2
This is heading 3
This is heading 4
This is heading 5
This is heading 6

做你的样品

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

sed -n 's|</\{0,1\}h[0-9]>||gp' YourFile

更换任何和在线，如果有修改，打印该行

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

更确切地说，假设标签

sed -n 's|^[[:space:]]*<\(h[0-9]>\)\(.*\)</\1|\2|p' YourFile
