[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'
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,
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() 6 C:\WINDOWS\system32> python 7 Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32 8 Type "help", "copyright", "credits" or "license" for more information. 9 >>> import requests 10 >>> res = requests.get("https://xxx.com/sitemap.xml") 11 >>> from xml.etree import cElementTree as ET 12 >>> root = ET.fromstring(res.text) 13 >>> root 14 <Element '{http://www.sitemaps.org/schemas/sitemap/0.9}urlset' at 0x00000274FAF49548> 15 >>>
解决:
单独导入fromstring方法
1 from xml.etree.ElementTree import fromstring, ElementTree 2 tree = ElementTree(fromstring(<your_xml_string>))
