如何通过python re在'\\ begin {minipage}'和'\\ end {minipage}'之间找到字符串？

Question

I have tried the following code:

strReFindString = u"\\begin{minipage}"+"(.*?)"
strReFindString += u"\\end{minipage}"
lst = re.findall(strReFindString, strBuffer, re.DOTALL)

But it always returns empty list.

How can I do? Thanks all.

As @BrenBarn said, u"\\\\b" parses as \\b ; and \\b is not a valid regexp escape, so findall treats it as b (literal b). u"\\\\\\\\b" is \\\\b , which regexp understands as \\b (literal backslash, literal b). You can prevent escape-parsing in the string using raw strings, ur"\\\\b" is equal to u"\\\\\\\\b" :

ur"\\b" == u"\\\\b"
# => True
