[issue16913] ElementTree tostring error when method='text'
Serhiy Storchaka added the comment:
Can you please provide an example of data for which the tostring method fails?
I can't reproduce this on simple data.
import xml.etree.ElementTree as ET
ET.tostring(ET.XML('rootbq/bwerty/root'), method='text',
encoding='unicode')
'qwerty'

[issue16913] ElementTree tostring error when method='text'
Serhiy Storchaka added the comment:
I found such example. It happens when the data contains XML entity.
ET.tostring(ET.XML('rootaamp;/root'), method='text',
encoding='unicode')
Traceback (most recent call last):
File stdin, line 1, in module
File /home/serhiy/py/cpython/Lib/xml/etree/ElementTree.py, line 1171, in
tostring
ElementTree(element).write(stream, encoding, method=method)

_serialize_text(write, self._root)
File /home/serhiy/py/cpython/Lib/xml/etree/ElementTree.py, line 1057, in
_serialize_text
write(part)
TypeError: string argument expected, got 'list'
Indeed, itertext() returns a list of lists instead of list of strings.
list(ET.XML('rootaamp;/root').itertext())
[['a', '']]
The bug is in the C implementation of itertext().

[issue16913] ElementTree tostring error when method='text'
New submission from Frank: Since upgrading to python 3.3 the tostring method fails when the output method is requested as text. Code like this: with open(fp, mode='rt') as f: data = f.read() tree, idmap = ET.XMLID(data) print(ET.tostring(tree, method='text', encoding='unicode')) Generates the following error: Traceback (most recent call last): File /home/john/Desktop/docs/Pear/pear.py, line 64, in pass_four print(ET.tostring(tree, method='text', encoding='unicode')) File /usr/lib/python3.3/xml/etree/ElementTree.py, line 1171, in tostring ElementTree(element).write(stream, encoding, method=method) File /usr/lib/python3.3/xml/etree/ElementTree.py, line 824, in write _serialize_text(write, self._root) File /usr/lib/python3.3/xml/etree/ElementTree.py, line 1057, in _serialize_text write(part) TypeError: string argument expected, got 'list' Whereas it used to return plain text with formatting tags stripped from the root element on prior versions of python. -- components: XML messages: 179523 nosy: Frank priority: normal severity: normal status: open title: ElementTree tostring error when method='text' versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16913 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
