Another attempt at creating post headers
Another attempt at creating post headers
The sed command works much better at transforming HTML is the delimeter/separator you use is not a /.
Hopefully, the follwing command will now work as intended:
echo "$html" | sed 's|</h2>|</h2> some more text|'
The code above is meant to append to text after the first <h2> tag it encounters in the "$html" string.
IF this post has a post header included, the above worked for me.
