Question

I am working on sed command to translate some text into another text.

cat text

           <strong>ABC
           </strong>

Commnad:

           sed -e 's|<strong>(.*?)</strong>|//textbf{1}|g'

Expected Outcome: \textbf{ABC}

but using above script i cannot convert it into expected output since there is new line between the tags. How to handle such cases?

Answer 1

This might work for you (GNU sed):

sed -r '$!N;s|(<)(strong>)([^\n]*)\n\s*\1/\2|//textbf{\3}|;P;D' file

or

sed '$!N;s|\(<\)\(strong>\)\([^\n]*\)\n\s*\1/\2|//textbf{\3}|;P;D' file
