如何在python中解析xml? [英] How to parse xml in python ?
问题描述
我必须从XML文档中提取`friendlyName`.
这是我当前的解决方案:
根= ElementTree.fromstring(urllib2.urlopen(XMLLocation).read())
用于root.iter(''{urn:schemas-upnp-org:device-1-0} friendlyName'')中的孩子:
返回child.text
我有什么更好的方法可以做到这一点(也许其他不涉及迭代的方法)?我可以使用XPath吗?
XML内容:
<！-语言:lang-xml->
< root xmlns ="urn:schemas-upnp-org:device-1-0">
< specversion>
< major> 1
<未成年人> 0
< device>

I have to extract `friendlyName` from the XML document.
Here''s my current solution:
root = ElementTree.fromstring(urllib2.urlopen(XMLLocation).read())
for child in root.iter(''{urn:schemas-upnp-org:device-1-0}friendlyName''):
return child.text
I there any better way to do this (maybe any other way which does not involve iteration)? Could I use XPath?
