问题 I have a file structured like this : A: some text B: more text even more text on several lines A: and we start again B: more text more multiline text I'm trying to find the regex that will split my file like this : >>>re.findall(regex,f.read()) [('some text','more text','even more text\non several lines'), ('and we start again','more text', 'more\nmultiline text')] So far, I've ended up with the following : >>>re.findall('A:(.*?)\nB:(.*?)\n(.*?)',f.read(),re.DOTALL) [(' some text', ' more

问题 I 'm using a php function want to create a function to trim all unnecessary white spaces from a multi line string.

问题 What I want to do is the following: read in multiple line input from stdin into variable A make various operations on A pipe A without losing delimiter symbols ( \n , \r , \t ,etc) to another command The current problem is that, I can't read it in with read command, because it stops reading at newline.

This works fine if the text is only on one line. But if
