Remove/replace html tags in bash

Question

I have a file with lines that contain:

 Some Text: More Text 

I want to remove the html tags and r

Answer 1

One way using GNU sed:

sed -e 's/<\/b>/-/g' -e 's/<[^>]*>//g' file.txt

Example:

echo "<li><b> Some Text:</b> More Text </li>" | sed -e 's/<\/b>/-/g' -e 's/<[^>]*>//g'

Result:

 Some Text:- More Text

Answer 2

If you strictly want to strip all HTML tags, but at the same time only replace the </b> tag with a -, you can chain two simple sed commands with a pipe:

cat your_file | sed 's|</b>|-|g' | sed 's|<[^>]*>||g' > stripped_file

This will pass all the file's contents to the first sed command that will handle replacing the </b> to a -. Then, the output of that will be piped to a sed that will replace all HTML tags with empty strings. The final output will be saved into the new file stripped_file.

Using a similar method as the other answer from @Steve, you could also use sed's -e option to chain expressions into a single (non-piped command); by adding -i, you can also read-in and replace the contents of your original file without the need for cat, or a new file:

sed -i -e 's|</b>|-|g' -e 's|<[^>]*>||g' your_file

This will do the replacement just as the chained-command above, however this time it will directly replace the contents in the input file. To save to a new file instead, remove the -i and add > stripped_file to the end (or whatever file-name you choose).
