Generally looks good, not in front of computer at the moment so I can't test just yet. Few comments:

1. can you lift the regex definitions out of the function? if you look just above your change, wbnsregex is lifted out of parse_wb_xml so that it's processed at load time

2. can you squash down to one commit?

3. does make lint pass?

Thank you for fast feedback (it is my very first PR on github),

1. not sure, because call re.exec() for //g modifying re.lastIndex.
   2-3) ok, i'll check with lint and prepare a new PR tomorrow
2. seems it also needs to add utf8read(attrValue)
