title: Converting XML to dataframe
body: <p>I want to convert a XML to a dataframe.
  I'm aware of XML::xmlToDataFrame, but it gives an error in my case.
  The XML can be found here:
  <a href="https://api.data.gov.hk/v1/historical-archive/get-file?url=https%3A%2F%2Fresource.data.one.gov.hk%2Ftd%2Ftraffic-detectors%2FrawSpeedVol-all.xml&amp;time=20211216-0513" rel="nofollow noreferrer">https://api.data.gov.hk/v1/historical-archive/get-file?url=https%3A%2F%2Fresource.data.one.gov.hk%2Ftd%2Ftraffic-detectors%2FrawSpeedVol-all.xml&amp;time=20211216-0513</a></p>
  <p>Thanks for all answers!</p>
