Generating xml in python and lxml
提问by user278618
I have this xml from sql, and I want to do the same by python 2.7 and lxml
我有来自 sql 的这个 xml，我想用 python 2.7 和 lxml 做同样的事情
<?xml version="1.0" encoding="utf-16"?>
<results>
<Country name="Germany" Code="DE" Storage="Basic" Status="Fresh" Type="Photo" />
</results>
Now I have:
我现在有：
from lxml import etree
# create XML
results= etree.Element('results')
country= etree.Element('country')
country.text = 'Germany'
root.append(country)
filename = "xmltestthing.xml"
FILE = open(filename,"w")
FILE.writelines(etree.tostring(root, pretty_print=True))
FILE.close()
Do you know how to add rest of attributes?
你知道如何添加其余的属性吗？

Note this also prints the BOM
请注意，这也会打印 BOM
>>> from lxml.etree import tostring
>>> from lxml.builder import E
>>> print tostring(
E.results(
E.Country(name='Germany',
Code='DE',
Storage='Basic',
Status='Fresh',
Type='Photo')
), pretty_print=True, xml_declaration=True, encoding='UTF-16')
??<?xml version='1.0' encoding='UTF-16'?>
<results>
<Country Status="Fresh" Type="Photo" Code="DE" Storage="Basic" name="Germany"/>
</results>

from lxml import etree
# Create the root element
page = etree.Element('results')
# Make a new document tree
doc = etree.ElementTree(page)
# Add the subelements
pageElement = etree.SubElement(page, 'Country',
name='Germany',
Code='DE',
Storage='Basic')
# For multiple multiple attributes, use as shown above
# Save to XML file
outFile = open('output.xml', 'w')
doc.write(outFile, xml_declaration=True, encoding='utf-16')

将我的评论提升为答案：
@sukbir is probably not using Windows. What happens is that lxml writes a newline (0A 00 in UTF-16LE) between the XML header and the body. This is then molested by Win text mode to become 0D 0A 00 which makes everything after that look like UTF-16BE hence the Chinese etc characters when you display it. You can get around this in this instance by using "wb" instead of "w" when you open the file. However I'd strongly suggest that you use 'UTF-8' (spelled EXACTLY like that) as your encoding. Why are you using UTF-16? You like large files and/or weird problems?
@sukbir 可能没有使用 Windows。发生的情况是 lxml 在 XML 标头和正文之间写入换行符（UTF-16LE 中的 0A 00）。然后它被 Win 文本模式骚扰为 0D 0A 00，这使得之后的所有内容看起来都像 UTF-16BE，因此显示时会出现中文等字符。在这种情况下，您可以通过在打开文件时使用“wb”而不是“w”来解决此问题。但是，我强烈建议您使用“UTF-8”（完全像那样拼写）作为编码。你为什么使用UTF-16？你喜欢大文件和/或奇怪的问题吗？

Save to XML file
保存到 XML 文件
doc.write('output.xml', xml_declaration=True, encoding='utf-16')
instead of:
代替：
outFile = open('output.xml', 'w')
doc.write(outFile, xml_declaration=True, encoding='utf-16')
