I would appreciate assistance doing in R what a colleague has done in
python. Unfortunately (for me), I have almost no experience with either
python or xml.

Within an xml file there is
and I need to extract those two values, 20120627 and 07322600

Here is the short python function. Even without knowing python, it's
conceptually clear what it does. I would like to do the same in R.

def readxmldate(xmlfile):
	tree = ET.parse(xmlfile)
	root = tree.getroot()
	for lev1 in root.findall('Esri'):
		xdate = lev1.find('CreaDate').text
		xtime = lev1.find('CreaTime').text
		return xdate, xtime

Thanks in advance
