Code review comment for lp:~adeuring/launchpad/bug-438169-parse-sysfs-attr

This branch adds a method _parseSysfsAttributes to the class SubmisisonParser.

The HWDB client in Karmic will no longer submit data from HAL; instead the data will come from udev, the content from some sysfs files etc. The new method parses the content from the new XML node <sysfs-attributes>.

Additonially I changed the content of the sample submission file l/c/l/scripts/tests/hardwaretest-udev.xml to reflect the real content sent by the HWDB client.

test: ./bin/test -t test_hwdb_submission_parser
