Top Forums Shell Programming and Scripting Extracting the value of an attribute tag from XML Post 302416213 by alister on Sunday 25th of April 2010 03:23:02 PM

Hello, JesterMania and welcome to the forums.

Assuming that all the relevant lines match the format of your sample data, if you have the value of the NAME attribute in a shell variable ($name in what follows), you can extract the value with the following AWK snippet:

Code:
$ name=Memory
$ awk -F\" -v n="$name" '/<ATTRIBUTE NAME="/ && $2==n {print $4}' data
512MB
$ name="CPU Speed"
$ awk -F\" -v n="$name" '/<ATTRIBUTE NAME="/ && $2==n {print $4}' data
3.0GHz
$ name="Video Card"
$ awk -F\" -v n="$name" '/<ATTRIBUTE NAME="/ && $2==n {print $4}' data
4870

Regards,
Alister
