Can xml.etree.ElementTree.write () be integer values ​​for this element?

Question

at the risk of screaming at asking such a simple question, but I’m baiting the Internet for answers, and this particular case seems to be widely avoided, and the documents are ambiguous:

Is it possible to use xml.etree.ElementTree.write () to write non-string values ​​in an element attribute? I always get:

TypeError: cannot serialize 0 (type int) 

when I try something like this:

 root = ET.Element('Tasks') d = {'priority': 1, 'status': 0, 'name': 'new task', 'index': 0} d = ET.SubElement(root, 'Settings', attrib=d) tree = ET.ElementTree(root) tree.write('/tmp/xmlTest') 

I worked on it several times, iterating over the corresponding dictionary and first turning all the values ​​into strings, but this does not seem to be correct, and before I process it again, I would like to know how it should be done correctly so as not to get used to the bad habit. So any insight would be greatly appreciated.

Cheers frank

Unlike XML data, XML attributes are texts. http://www.w3schools.com/xml/xml_attributes.asp

It is up to you to serialize the attributes for strings before serializing the XML.
