I have the following code...it is mostly working. Except I am wanting to write the result of sed into the variable newData. Have viewed many other posts, and none have managed to work for me.

newin="<font color='default'>Default Color has been choosen.</font>"

newData="$newin" | sed 's/&lt;/</g; s/&gt;/>/g; s/<[^>]*>//g'

if [[ ${newin:0:1} == "<" ]]
then

    #this echo works like it should
    echo "$newin" | sed 's/&lt;/</g; s/&gt;/>/g; s/<[^>]*>//g'

    #this echo works like it should

    echo "$newin"

    #The variable newData does not seem to capture the data
    newData=${newin} | sed 's/&lt;/</g; s/&gt;/>/g; s/<[^>]*>//g'
    echo "[$newdata]"

fi

it outputs:

Default Color has been choosen.
<font color='default'>Default Color has been choosen.</font>

Have you tried `newData=$(${newin} | sed 's/<//g; s/<[^>]*>//g')`? – Mad Physicist Aug 22 '16 at 18:39
no luck using the $(${newin} ....approach – user1305988 Aug 22 '16 at 18:42
it would work with `newData=$(echo ${newin} | sed 's/<//g; s/<[^>]*>//g')` – Jean-François Fabre Aug 22 '16 at 18:48
@Jean-FrançoisFabre -- That works perfect. I wasn't even thinking along the lines of just wrapping the entire original command into it, but it works flawlessly. Thanks. – user1305988 Aug 22 '16 at 18:56
@Jean-FrançoisFabre. Good call on the echo. – Mad Physicist Aug 22 '16 at 19:09
