Question Match from one pattern to second occurrence of second pattern
Given an XML file that contains (NOT "consists of"):

Code:
                </dict>
                <key>system.</key>
                <dict>
                        <key>rule</key>
                        <string>default</string>
                </dict>
                <key>system.burn</key>
                <dict>
                        <key>class</key>
                        <string>allow</string>
                        <key>comment</key>
                        <string>For burning media.</string>
                        <key>default-button</key>
                        <dict>
                                <key>ar</key>
                                <string>نسخ قرص</string>
                                <key>ca</key>
                                <string>Gravar</string>
                                <key>cs</key>
                                <string>Vypálit</string>
                                <key>da</key>
                                <string>Brćnd</string>
                                <key>de</key>

I want to isolate and operate on the lines between <key>system.burn</key> and the second occurrence of <dict>, so:

Code:
                        <key>class</key>
                        <string>allow</string>
                        <key>comment</key>
                        <string>For burning media.</string>
                        <key>default-button</key>

Now, sed -n '/<key>system.burn<\/key>/,/<dict>/2 p' /etc/authorization would get me what I want... except I'm on a Mac, and so do not have GNU see. That gets me "invalid command code 2" I can delete the 2 and wind up with a valid pattern, but it only returns:

Code:
		<key>system.burn</key>
		<dict>

I don't want to just return the six lines after <key>system.burn</key> as I cannot be positive that there will always just be six lines.

I have a feeling awk is going to be the answer here, but I've got a long curve to climb with awk. I'm proud of myself for being able to print $2 or even $NF, so that tells you how advanced I am there :-P
