* xpath
* This is a utility that can be used by network scripts to extracts bits and

* This is still a bit inconvenient, especially if you need to extract more than
* one of two elements, since we have to parse and reparse the XML file every
* time you invoke this program.
* On the other hand, there's a few rather nifty things you can do. For instance,
* the following will extract addres/prefixlen pairs for every IPv4 address
* listed in an XML network config:
*
* wicked xpath \
* --reference "interface/protocol[@family = 'ipv4']/ip" \
* --file vlan.xml \
* '%{@address}/%{@prefix}'
*
* The "reference" argument tells wicked to look up the <protocol>
* element with a "family" attribute of "ipv4", and within that,
* any <ip> elements. For each of these, it obtains the address
* and prefix attribute, and prints it separated by a slash.
