Actually this was not the case in my test and the script worked as it was shown here. For reference, i used Linux (Kernel 4.10.42) and GNU-sed 4.2.2, shell is Kornshell 93 u+.

Code:
man sed
...
d

Delete pattern space. Start next cycle.

You must test with an input file that has a further <Description>xyz</Description> after (outside) the <OfferDefinition Id=...> ... </OfferDefinition> block.

Better readable in two lines
Code:
sed '
  /<OfferDefinition Id="/ {h; s/.*=" *//; s/" *>.*//; x; n;}
  /<Description>/ {H; x; s/\(.*\)\n\(.*<Description>\)/\2\1_/;}
' file.txt

Of course digging out the saved value from the hold space is a bit of a hack (also in the previous post).
While the other codes using awk were giving slight errors (while printing the 'id' in 'description', they were replacing the existing text) which could be tweaked, your code worked perfectly. Many Thanks!

Thanks Rudi, you are always helpful. Worked with a little bit of tweak in separators:

Code:
 awk -F\" '/OfferDefinition>|="/ {ID = $2"_"} /Description>/ {sub (/>/, "&" ID )} 1' file

However, can you explain why you have used '1' at the end? I tried removing it to understand but the code doesn't work without it...

awk works in
Code:
pattern {action}

pairs. If pattern evaluates to TRUE, the respective action is executed. 1 is always TRUE, and for a missing actions the default, print, will be taken.
