你差点就拿到了。我的建议是，您应该再次阅读xml.etree.ElementTree模块的文档。你知道吗
https://docs.python.org/3/library/xml.etree.elementtree.html
您正在使用XML解析器解析XML。这个Python模块允许您访问解析树的元素对象。每个元素对象都附带了一个属性字典。因此，对于每个元素，您可以看到是否有title属性。请看下面（注意：我对您的代码做了一些修改）：
import xml.etree.ElementTree as ET import requests from bs4 import BeautifulSoup # I am just getting the HTML source code for the web page here r = requests.get('https://en.wikipedia.org/wiki/Fitzroy,_South_Australia') soup = BeautifulSoup(r.content, 'html.parser') xml_text = soup.prettify() root = ET.fromstring(xml_text).findall('.//') print(root[0][1].text) for element in root: if 'title' in element.attrib: print(element.attrib['title'])
手动遍历树中的每个元素并测试title属性是否存在可能不是最有效的方法。更好的方法是使用XPath表达式。所以，在你的例子中，它看起来是这样的：
import xml.etree.ElementTree as ET import requests from bs4 import BeautifulSoup # I am just getting the HTML source code for the web page here r = requests.get('https://en.wikipedia.org/wiki/Fitzroy,_South_Australia') soup = BeautifulSoup(r.content, 'html.parser') xml_text = soup.prettify() elements = ET.fromstring(xml_text).findall('.//*[@title]') for element in elements: print(element.text)
我在上面链接的模块文档中都提到了这一点。下次一定要仔细阅读。你知道吗
