How to access value element in iTunes xml using ElementTree?

I'm trying to 'export' from an xml playlist to an html table for sharing. But the iTunes library file uses pairs of key values instead of more meaningful XML tags. Is there a simple way to also get the <value> in these key/value pairs?

This gets me as far as the value of the <key>, i.e. Track ID Name Artist Album Artist etc., but I can't seem to find a way to also get the value of the next key, i.e. <integer> 49924, or <string> Ep. 35 | What Do Your... Can (should) I do this with ElementTree or should I move along to Regular Expressions or some other library? Thanks!

Solution

Question: How to access value element in iTunes xml

The following solution using lxml.etree.iterparse appends a <key> tag with the following <value> tag to build a Python dict {key:value}.

Used module and built-in functions:

from lxml import etree
import io

class Playlist:
    def __init__(self, fh):
        """
        Initialize 'iterparse' to generate 'start' and 'end' events on all tags

        :param fh: File Handle from the XML File to parse
        """
        self.context = etree.iterparse(fh, events=("start", "end",))

    def _parse(self):
        """
        Yield only at 'end' event, except 'start' from tag 'dict'
        :return: yield current Element
        """
        for event, elem in self.context:
            if elem.tag == 'plist' or \
                    (event == 'start' and not elem.tag == 'dict'):
                continue
            yield elem

    def _parse_key_value(self, key=None):
        _dict = {}
        for elem in self._parse():
            if elem.tag == 'key':
                key = elem.text
                continue

            if elem.tag in ['integer', 'string', 'date']:
                if not key is None:
                    _dict[key] = elem.text
                    key = None
                else:
                    print('Missing key for value {}'.format(elem.text))

            elif elem.tag in ['true', 'false']:
                _dict[key] = elem.tag == 'true'

            elif elem.tag == 'dict':
                if not key is None:
                    _dict[key] = self._parse_dict(key)
                    key = None
                else:
                    return elem, _dict
            else:
                print('Unknow tag {}'.format(elem.tag))

    def _parse_dict(self, key=None):
        elem = next(self._parse())
        elem, _dict = self._parse_key_value(elem.text)
        return _dict

    def __iter__(self):
        for elem in self._parse():
            if elem.tag == 'dict':
                yield self._parse_dict()
            else:
                print('Unknow tag {}'.format(elem.tag))

if __name__ == "__main__":

    data = b'''<?xml...'''

    with io.BytesIO(data) as in_xml:
        for record in Playlist(in_xml):
            print("record:{}".format(record))

            for key, value in record.items():
                print("{}:{}".format(key, value))

Output:

record:{'Major Version': '1', 'Minor Version': '1'... (omitted for brevity)
    Major Version:1
    Minor Version:1
    Date:2019-01-24T10:31:15Z
    Tracks:{'99244': {'Track ID': '99244', 'Artist': 'Blaze Podcast Network', ... (omitted for brevity)}}
