dicttoxml，以数字为键

Question

from dicttoxml import dicttoxml

ArrayWithDigitKey={2:"vale"}
xml =dicttoxml(ArrayWithDigitKey)

我得到了这个错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/dicttoxml.py", line 393, in dicttoxml
    convert(obj, ids, attr_type, item_func, cdata, parent=custom_root), 
  File "/usr/local/lib/python2.7/site-packages/dicttoxml.py", line 189, in convert
    return convert_dict(obj, ids, parent, attr_type, item_func, cdata)
  File "/usr/local/lib/python2.7/site-packages/dicttoxml.py", line 214, in convert_dict
    key, attr = make_valid_xml_name(key, attr)
  File "/usr/local/lib/python2.7/site-packages/dicttoxml.py", line 145, in make_valid_xml_name
    if key.isdigit():
AttributeError: 'int' object has no attribute 'isdigit'

检查一次错误会让你知道哪里出了问题。

“ArrayWithDigitKey”的键需要是一个整数，但采用字符串的形式。

因此，您必须按如下方式定义字典，并且它应该会重新开始工作。

ArrayWithDigitKey={'2':"vale"}
