Yam*_*088 -1 regex bash perl grep curl
我需要解析HTML文件并删除除锚标记之外的所有内容.例如:
<html>
<body>
<p>boom</p>
<a href="/blah" rel="no-follow">Example</a>
</body>
</html>
我只需要保持:
<a href="/blah" rel="no-follow">Example</a>
我正在使用cURL来检索html和我发现的一小段代码,除了标签的锚文本之外.这就是我正在使用的:
curl http://www.google.com 2>&1 | perl -pe 's/\<.*?\>//g'
有一个简单的命令行方式来做到这一点？我的最终目标是将其放入bash脚本并执行它.我很难理解正则表达式和perl.
使用Mojolicious命令行工具mojo:
mojo get http://www.google.com 'a'
