XML和Python：获取根元素中声明的名称空间

如何访问XML树根元素处的多个

xmlns

声明？例如：

import xml.etree.cElementTree as ET
data = """<root
             xmlns:one="http://www.first.uri/here/"
             xmlns:two="http://www.second.uri/here/">

          ...all other child elements here...
          </root>"""

tree = ET.fromstring(data)
# I don't know what to do here afterwards

---

我不确定如何使用

xml.etree

实现这一点，但您可以使用：

import lxml.etree as le
data = """<root
             xmlns:one="http://www.first.uri/here/"
             xmlns:two="http://www.second.uri/here/">

          ...all other child elements here...
          </root>"""

tree = le.XML(data)
print(tree.nsmap)
# {'two': 'http://www.second.uri/here/', 'one': 'http://www.first.uri/here/'}

将lxml.etree导入为le
data=”“”
…此处的所有其他子元素。。。
"""
tree=le.XML（数据）
打印（tree.nsmap）
#{'2'：'http://www.second.uri/here/'一'：'http://www.first.uri/here/'}

import lxml.etree as le
data = """<root
             xmlns:one="http://www.first.uri/here/"
             xmlns:two="http://www.second.uri/here/">

          ...all other child elements here...
          </root>"""

tree = le.XML(data)
print(tree.nsmap)
# {'two': 'http://www.second.uri/here/', 'one': 'http://www.first.uri/here/'}
