我在Unix脚本中使用grep从html文件中得到了一行，但是我不知道如何使用sed提取文本

Question

i'm making a shell script that shows title and an artist of a song that is played on the radio. i got html file and i found the line that i needed, using grep, but can't figure out how to extract the text that i need. the line that i got is

<div class="n Title">title, different every time </div><div class=n Artist">artist that changes also</div> 

how do i extract the title and the artist using unix commands? i have tried many ways but it didn't work properly.

Answer 1

grep -Po 'Title">\K[^<]*'

gives you title, same idea you can get the Artist. but keep in mind, using regex to "parse" xml/html is risky, for example, the website change the html source, make this in separated lines... or they add some other attributes, or add some other css classes after Title ...
