我通过生成的 evernote 和a HTML page分享了一条记事。 我想得到头衔和本笔记的内容，所以代码如下：
import re

title_pattern = re.compile('(?<=<title>).+(?=</title>)')
content_pattern = re.compile('(?<=class=\"divider\"></div>).+(?=<a class=\"save-button)')
title= re.search(title_pattern,resource)
content = re.search(content_pattern,resource)
if title:
print title.group()
if content:
print content.group()
# if __name__=='__main__':main()
输出：
python re
为什么只获得头衔？以及如何获取此笔记的内容？
答案 0 :(得分：2)
您的问题是内容包含换行符。默认情况下，.与换行符不匹配。
因此，您应该使用re.DOTALL：
content_pattern = re.compile('(?<=class=\"divider\"></div>).+(?=<a class=\"save-button)', re.DOTALL)
使.匹配换行符。然后就行了。

我不完全明白你想做什么，但似乎BeautifulSoup可以帮助你。
