找到（）后replaceWith（）不工作（使用BeautifulSoup） [英] find() after replaceWith() doesn't work (using BeautifulSoup)

问题描述

请考虑以下Python会话：

Please consider the following python session:

>>> from BeautifulSoup import BeautifulSoup
>>> s = BeautifulSoup("<p>This <i>is</i> a <i>test</i>.</p>"); myi = s.find("i")
>>> myi.replaceWith(BeautifulSoup("was"))
>>> s.find("i")
>>> s = BeautifulSoup("<p>This <i>is</i> a <i>test</i>.</p>"); myi = s.find("i")
>>> myi.replaceWith("was")
>>> s.find("i")
<i>test</i>

请注意第4行后s.find的（I）输出缺！

Please note the missing output of s.find("i") after line 4!

什么是这个原因？有没有解决办法？

What's the reason for this? Is there a workaround?

编辑：其实，这个例子不能证明的用例，它是：

Actually, the example doesn't demonstrate the usecase, which is:

myi.replaceWith(BeautifulSoup("wa<b>s</b>"))

每当插入部分包含本身平凡的html code，我不明白你怎么能代替这个语法别的东西。只要有

Whenever the inserted part contains itself nontrivial html code, I don't see how you could replace this syntax with something else. Just having

myi.replaceWith("wa<b>s</b>")

将实体取代HTML特殊字符。

will replace the html special chars by entities.

推荐答案

简单的回答：你的电话后， replaceWith ，再生和清洁取值致电 S = BeautifulSoup（s.renderContents（））。然后，你可以找到试。

Simpler answer : after your call to replaceWith, regenerate and clean s by calling s = BeautifulSoup(s.renderContents()). Then you can find again.
