问题描述

我正在解析一个 xml，进行一些更改并保存到一个新文件中.它有我想保留的声明 <?xml version="1.0" encoding="utf-8" Standalone="yes"?> .当我保存新文件时，我丢失了 standalone="yes" 位.我怎样才能把它留在里面?这是我的代码:

I have an xml I am parsing, making some changes and saving out to a new file. It has the declaration <?xml version="1.0" encoding="utf-8" standalone="yes"?> which I would like to keep. When I am saving out my new file I am loosing the standalone="yes" bit. How can I keep it in? Here is my code:

templateXml = """<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<package>
  <provider>Some Data</provider>
  <studio_display_name>Some Other Data</studio_display_name>
</package>"""

from lxml import etree
tree = etree.fromstring(templateXml)

xmlFileOut = '/Users/User1/Desktop/Python/Done.xml'   

with open(xmlFileOut, "w") as f:
    f.write(etree.tostring(tree, pretty_print = True, xml_declaration = True, encoding='UTF-8'))

解决方案

您可以将 standalone 关键字参数传递给 tostring():

You can pass standalone keyword argument to tostring():

etree.tostring(tree, pretty_print = True, xml_declaration = True, encoding='UTF-8', standalone=True)
