Re: [PATCH] Fixed parsing of strings with multiple values in pyudev



Hi,

Why are you using a re.split and not just a regular split,
also what happens if name has any re special chars in it,
is there a re escape function you can use?

Regards,

Hans

Some of the values which are returned by udev are strings,
which contain more values for the same key.
The string format is "val1 key=val2 key=val3 ...".
This fix makes sure we split this string into a list of values.
