We'll look at one approach to XML serialization using the built-in libraries. This will build a document from individual tags. A common alternative approach is to use Python introspection to examine and map Python objects and class names to XML tags and attributes.
Here's our XML serialization:
import xml.etree.ElementTree as XMLdef serialize_xml(series: str, data: List[Pair]) -> bytes: """ >>> data = [Pair(2,3), Pair(5,7)] >>> serialize_xml( "test", data ) b'<series name="test"><row><x>2</x><y>3</y></row><row><x>5</x><y>7</y></row></series>' """ doc = XML.Element("series", name=series) for row in data: row_xml = XML.SubElement(doc, "row") x = XML.SubElement(row_xml, "x") x.text = str(row.x) y = XML.SubElement(row_xml, ...
