This works around xmldom versions greater than 0.8.8 & up to 0.8.10 seemingly not supporting use of Object.keys on NodeList to iterate over currently existing keys.
It should be noted I have not investigated whether
Object.keys(NodeList)
is allowed per DOM specification and it could be that there exists a regression in xmldom. Track xmldom/xmldom#583 for relevant discussion.Original patch from #835 (comment)
