Question

您好我将wordpress博客导出到其他CMS，我需要在上传到新平台之前从html中删除打开和关闭[caption]标签及其内容，而不删除标记＆＃ 39;包含在内。其余的代码在这里是https://github.com/thmcmahon/wp2nb。

理想情况下，我希望将其实现为如下函数：

def strip_caption_tags(content):
  no_captions = do_some_stuff_presumably_regex(content)
  return caption

这是数据的一个例子：

<![CDATA[[caption id="attachment_5582" align="alignleft" width="1024" caption="Out on Lake Burley Griffin with members of the Canberra Ice Dragons Paddle Club, January 2014"]<a href="http://www.andrewleigh.com/blog/wp-content/uploads/2014/01/ACT-Dragon-Boat-3.jpg"><img class="size-large wp-image-5582" title="ACT Dragon Boat 3" src="http://www.andrewleigh.com/blog/wp-content/uploads/2014/01/ACT-Dragon-Boat-3-1024x682.jpg" alt="" width="1024" height="682" /></a>[/caption]

Answer 1

这是您的问题的答案，但我不是100％确定您提出有关转换数据的正确问题。在将数据库导出到XML之前，这可能更容易处理，但是如果你想用python中的regex替换内容：

import re
contents = //... get your post contents here
contents = re.sub(r'\[/?caption[^\]]*?\]', '', contents)

对于正则表达式：

\[匹配文字左方括号[
/?可选地匹配正斜杠/
caption匹配caption
[^\]]*?对于不是右方括号]的任何字符的惰性匹配
\]匹配文字右方括号

这将匹配[caption foo="bar"]以及[/caption]。

使用您的示例here on Regex101及其他说明查看其实际操作。
