Python web crawlers commonly use the following four parsing Database Assistants: re regular, etree XPath, scrapy XPath, and beautifulsoup. (Because etree XPath and scrapy XPath have different usage, they are not classified as one type.) This article introduces beautifulsoup, a rare pitfall, as shown in the example below: example 1 ): content = "<HTML> <body> <Div class =" TD-post-content TD-Pb-padding-side "> <p> </P> <p> </P> <p> ????????????????? ????????????????????????????? ???????????????????????????????????????? ????????????????????????? ????????????????????????? ?????????????????????????? </P> <p> </P> <p> <br/> <em> <br/> ?????? </Em> ??????????????????????? ???????????? ?????????????????? ????????????????????????????????????? </P> </div> </body>
