python - 如何使用 xml.etree.ElementTree 将“standalone="yes" 添加到 XML 声明

Question

我已经尝试查看与此类似的其他问题，但似乎没有人回答 xml.etree.ElementTree。

目前我的代码看起来像这样（它只是一个简单的 XML 生成器）

import xml.etree.ElementTree as ET

example1=ET.Element('example1')
example2=ET.SubElement(example1, 'example2').text='1234'
tree = ET.ElementTree(example1)
NewXML='example.xml'

tree.write(NewXML,encoding = 'UTF-8', xml_declaration = True)

目前的输出只是这个文件：

<?xml version='1.0' encoding='UTF-8'?>
<example1>
    <example2>1234</example2>
</example1>

我想添加声明 Standalone = 'yes' 所以输出应该是：

<?xml version='1.0' encoding='UTF-8' standalone = 'yes'?>
<example1>
    <example2>1234</example2>
</example1>

然而，这就是我遇到问题的地方。

我试过了

tree.write(NewXML,encoding = "UTF-8", xml_declaration = True, standalone = True)

tree.write(NewXML,encoding = "UTF-8", xml_declaration = True, standalone = "yes")

但我收到此错误：TypeError: write() got an unexpected keyword argument 'standalone'

自己写声明怎么样？

>>> import xml.etree.ElementTree as ET
>>> example1=ET.Element('example1')
>>> example2=ET.SubElement(example1, 'example2').text='1234'
>>> tree = ET.ElementTree(example1)
>>> NewXML='example.xml'
>>> out = open(NewXML, 'wb')
>>> out.write(b'<?xml version="1.0" encoding="UTF-8" standalone = "yes"?>\n')
58
>>> tree.write(out, encoding = 'UTF-8', xml_declaration = False)
>>> out.close()
>>>
