[xml]AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getroot'

 >>> import requests
 >>> res = requests.get("https://xxx.com/sitemap.xml")
 >>> from xml.etree import cElementTree as ET
 >>> tree = ET.fromstring(res.text)
 >>> tree
 <Element '{http://www.sitemaps.org/schemas/sitemap/0.9}urlset' at 0x00000249FF7B9548>
 >>> tree.getroot()
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getroot'

错误发生情形:

xml模块解析xml格式字符串的时候, 无法调用getroot方法

问题原因是此处的fromstring直接返回的就是root,

 >>> from xml.etree.ElementTree import fromstring, ElementTree
 >>> tree = ElementTree(fromstring(a))
 >>> tree.getroot()
 <Element '{http://www.sitemaps.org/schemas/sitemap/0.9}urlset' at 0x0000024980A19818>
 >>> exit()

解决:

单独导入fromstring方法

 from xml.etree.ElementTree import fromstring, ElementTree
 tree = ElementTree(fromstring(<your_xml_string>))
