One more question..
I tried to use the awk snippet replacing <string1> with a variable and it didn;t work:

Code:

-bash-4.1$ awk '/measInfo/ || s {s=s?s"\n"$0:$0} /<\/measInfo>/{if (s ~ /string1/) print s; s=""}' asd | wc -l
38
-bash-4.1$
-bash-4.1$ targetItem=string1
-bash-4.1$ awk "/measInfo/ || s {s=s?s\"\n\"$0:$0} /<\/measInfo>/{if (s ~ /$targetItem/) print s; s=\"\"}" asd | wc -l
0

I replaced single quotes with double quotes and added "\" before other double quotes inside the snippet.
But it doesn;t work. Id doesn't give me a syntax error but doesn;t return nothing.
I think the variable substitution is not done..
Any idea how can I accomplis this or what am I doing wrong ?
