Grep specific words between quotation marks

Question

Lets say I have a line like this:

<group description="" name="voice_guidance" comment="Missing description!" status="0">

I wish to grep with a bash script only the comment saying:

Missing description!

Could you clarify your question? At least, add an example – Andrii Abramov Aug 01 '17 at 11:54 — Andrii Abramov, Aug 01 '17 at 11:54

If you only want the comment, you can use this: grep -Po 'comment="\K[^"]*'

\K means to only output the part following from there and then all the non-quote characters following are output.

You can use straightforward solution:

grep '"Missing description!"' filename.html

Where filename.html is a target file.

Here is an example output:

P.S. In such when I see HTML and RegEx both present in the same question, I recommend to read this answer: https://stackoverflow.com/a/1732454/5091346

Good idea, but the text is not always the same. – Bert Aug 01 '17 at 12:04
Sorry, @Bert. Seems that your question is not clear enough for me. – Andrii Abramov Aug 01 '17 at 12:05

If you can't use the perl-regexp (-P) in @rubystallion's fine answer, use:

$ grep -o "comment=\"[^\"]\+" file | grep -o "[^\"]\+$"
Missing description!
