ParseXml parses an UTF-8 encoded byte array and returns an xml.XmlDocument. By default the parsing options ignore validation
and suppress errors and warnings. This allows one to liberal in accepting badly-formed documents, but is not standards-compliant.
If the content is not UTF-8 encoded or you want to customize the parsing options, you should call the Parse or ReadFile functions
found in the github.com/moovweb/gokogiri/xml package. The xml.StrictParsingOption is conveniently provided for standards-compliant
