我正在使用以下代码片段来读取下面显示的示例 xmlTest1.xml 文件。

with open("xmlTest1.xml") as xml_file:
    xml_dict = xmltodict.parse(xml_file.read(), force_list={'team'}, attr_prefix="")
    xml_file.close()
    xml_file_unparsed = xmltodict.unparse(xml_dict, pretty=True, cdata_key='#text', 
    full_document=False, short_empty_elements=True)
    print ("Round trip xml file is: ", xml_file_unparsed)

在阅读了 parse() 之后，我执行了一个 unparse()，然后是一个未解析的 print()。未解析的文件与原始 XML 文件不同。我需要 unparsed() 文件与输入相同。

为什么会发生这种情况，我该如何纠正？？？？

在这里很迷失。请帮忙。

这里你设置attr_prefix=""了，所以xmltodict在调用unparse时不识别属性（默认设置为attr_prefix="@"）

只需将其删除，它应该没问题：

with open("xmlTest1.xml") as xml_file:
xml_dict = xmltodict.parse(xml_file.read(), force_list={'team'})
xml_file.close()
xml_file_unparsed = xmltodict.unparse(xml_dict, pretty=True, cdata_key='#text', 
full_document=False, short_empty_elements=True)
print ("Round trip xml file is: ", xml_file_unparsed)
