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

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

 

錯誤發生情形:

xml模塊解析xml格式字符串的時候, 沒法調用getroot方法

問題緣由是此處的fromstring直接返回的就是root, 

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

解決:

單獨導入fromstring方法

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