[SOLVED] Using Grep to Extract Content Between HTML Tags

Issue

I am writing C program that gets a file and then uses grep to parse the file and print out text between HTML tags. Using:

grep -o '<font color="#FFCC00" SIZE=+1>' PROJECTS.HTML

I get a correct output of 41 instances of that tag.

Same with grep -o '</font>' PROJECTS.HTML.

Is is not possible to use grep to extract what is between the tags? For example using: grep -o '(<font color="#FFCC00" SIZE=+1>).*?(</font>)' PROJECTS.HTML.

Here is sample of the HTML:

<li>                          
  <A HREF="./CS448/marbles_2020_1.tar" target="main">
  <font color="#FFCC00" SIZE=+1>
   Marbles - A marbles game (V2020) written on OPENGL for Linux. 
  </font>
  </A>
 </li>                          
 <li>                          
  <A HREF="./CS448/marbles_2020_2.tar" target="main">
  <font color="#FFCC00" SIZE=+1>
   Marbles - A marbles game (V2020) written on OPENGL for Linux. 
  </font>
  </A>
 </li>                          
</ul>

Solution

A million years ago, I would have used something like:

/<font color="#FFCC00" SIZE=+1>/,/<\/font>/p

as a script for sed...

(This goes back a long way... I may be wrong about bits of that.)

Seems both upper & lower case has been used for attributes. This could be a problem...

IF, as you wrote, this is all that is in the file, use inverse thinking and "grep out" the rows/tags you don't want. Something like:

grep -v "<li>" -v "</li>"...

Just an idea...
