Remove XML comments using Regex in bash

Question

I want to remove XML comments in bash using regex (awk, sed, grep...) I have looked at other questions about this but they are missing something. Here\'s my xml code

Answer 1

The most simple solution to remove all comments from a textfile I could come up with is:

sed 's//-->\x0/g' | grep -zv '^\0


        
    

Than the grep -z will treat that character as "line separator"

• \n
  \n\n\n \n \n
  \n

grep -v will remove the middle part.

And finally tr -d will remove the \0 again.

In this case it should be applied to both files before comparing e.g.:

diff <(sed 's//-->\x0/g' file1.xml | grep -zv '^/-->\x0/g' file2.xml | grep -zv '^/-->\x0/g' | grep -zv '^
