Question

Shell, bash : grep the html tag in multiple lines

How do I grep from tr to /td in input.txt?

   <tr>
   <td>Answer</td>

My code is

 grep -o "<tr>.*</td>" input.txt > output.txt

But it returns nothing..

You'd be better off using a HTML parser, but for simple needs a range-based awk solution may work

awk '/<tr>/,/<\/td\>/' input.txt
