问题描述
我尝试在此问题中使用答案，但无法使其正常工作：
I have tried to use the answer in this question, but can't make it work: How to create "virtual root" with Python's ElementTree?
这是我的代码：
import xml.etree.cElementTree as ElementTree
from StringIO import StringIO
s = '<?xml version=\"1.0\" encoding=\"UTF-8\" ?><!DOCTYPE tmx SYSTEM \"tmx14a.dtd\" ><tmx version=\"1.4a\" />'
tree = ElementTree.parse(StringIO(s)).getroot()
header = ElementTree.SubElement(tree,'header',{'adminlang': 'EN',})
body = ElementTree.SubElement(tree,'body')
ElementTree.ElementTree(tree).write('myfile.tmx','UTF-8')
当我打开生成的 myfile.tmx文件时，它包含以下内容：
When I open the resulting 'myfile.tmx' file, it contains this:
<?xml version='1.0' encoding='UTF-8'?>
<tmx version="1.4a"><header adminlang="EN" /><body /></tmx>
我想念什么？还是有更好的工具？
What am I missing? or, is there a better tool?
推荐答案
您可以使用及其 tostring 函数：
from lxml import etree
s = """<?xml version="1.0" encoding="UTF-8"?>
<tmx version="1.4a"/>"""
tree = etree.fromstring(s)
header = etree.SubElement(tree,'header',{'adminlang': 'EN'})
body = etree.SubElement(tree,'body')
print etree.tostring(tree, encoding="UTF-8",
xml_declaration=True,
pretty_print=True,
doctype='<!DOCTYPE tmx SYSTEM "tmx14a.dtd">')
=>
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE tmx SYSTEM "tmx14a.dtd">
<tmx version="1.4a">
<header adminlang="EN"/>
<body/>
</tmx>
