Find previous occurrence of an element
问题 I have the following html: <h4>Testing</h4> <h3>Test</h3> <h3>Test2</h3> <h4>Testing2</h4> If I have the element <h3>Test2</h3> referenced in a variable, how can I find <h4>Testing</h4> ? The one before the referenced element, not after. 回答1: Use .previous_sibling: element.previous_sibling Or, .find_previous_sibling() to explicitly find the first preceding h4 tag: element.find_previous_sibling('h4') Demo: >>> from bs4 import BeautifulSoup >>> data = """ ... <h4>Testing</h4> ... <h3>Test</h3>
