Hi,
python2.7 -c 'from lxml import objectify; root =
objectify.fromstring("<root><x>1000_000</x></root>"); print(root.x,
type(root.x), type(root.x.pyval)); print(root.x.text, type(root.x.text));
print(objectify.dump(root))'
('1000_000', <type 'lxml.objectify.StringElement'>, <type 'str'>)
('1000_000', <type 'str'>)
root = None [ObjectifiedElement]
x = '1000_000' [StringElement]
python3.6 -c 'from pytaf.objectify.xmsg import *; from lxml import etree,
objectify; root = objectify.fromstring("<root><x>1000_000</x></root>");
print(root.x, type(root.x), type(root.x.pyval)); print(root.x.text,
type(root.x.text)); print(objectify.dump(root))'
1000000 <class 'lxml.objectify.IntElement'> <class 'int'>
1000_000 <class 'str'>
root = None [ObjectifiedElement]
x = 1000000 [IntElement]
According to https://www.w3.org/TR/xmlschema-2/#integer 1000_000 is not a valid
integer literal. But it is for Python since 3.6.
The magic lxml.objectify type lookup/annotation simple does int(s) and
interprets success as "shall be interpreted as int".
One could argue that - when parsing XML data - this is not the
right/sane/intuitive choice. Or is it? :-)
<x>1000_000</x> is not an integer in the XML world.
Opinions if that should be changed, maybe switchable? Would it break things for
you?
Of course, Python 3.6 (and consequently this objectify behavior) is 5 years old
now and nobody seemed bothered.
Plus you can customize the default lookup mechanism anyway.
Cheers,
