python - XBRL 格式 XML 根节点属性 Python

Question

我想从此链接获取根节点的所有属性： http ://www.sec.gov/Archives/edgar/data/75829/000144530512003029/pll-20120731.xml

Main_Page = urllib2.urlopen("http://www.sec.gov/Archives/edgar/data/75829/000144530512003029/pll-20120731.xml")
                tree = ET.parse(Main_Page)
                root = tree.getroot()
List=root.attrib

但是 List 向我展示了 0 Length Array。那么我怎样才能获得属性值。而且它没有任何属性键。

Answer 1

请参阅ElementTree：使用命名空间和限定名称

import urllib2
from xml.etree import ElementTree as ET

Main_Page = urllib2.urlopen("http://www.sec.gov/Archives/edgar/data/75829/000144530512003029/pll-20120731.xml")
for event, (name, value) in ET.iterparse(Main_Page, ['start-ns']):
    print name, ':', value
