simple way to locate an element from a parsed xml file

[dsayling]

As someone who parses large xml files, I would like a way to locate a specific element within the file based on the parsed model, so that I can report to users where there are issues within the large xml files.

I understand that this would require generating models that inherit from some type of base, or perhaps setting attributes on the built models as its parsed...

Possible ideas:

Given

from xsdata.formats.dataclass.context import XmlContext
from xsdata.formats.dataclass.parsers import XmlParser
from xsdata.formats.dataclass.parsers.config import ParserConfig
from tests.fixtures.primer import PurchaseOrder

config = ParserConfig()
context = XmlContext()
parser = XmlParser(context=context, config=config)

order = parser.parse("tests/fixtures/primer/sample.xml", PurchaseOrder)

Then

>>> order.bill_to._meta_.line_number
10

or

order.bill_to.get_xpath() # or something
# can then be used with element tree
etree.parse("tests/fixtures/primer/sample.xml").xpath(order.bill_to.get_xpath())[0].source_line
