regex

问题 I would like to split a string using multiple character delimiters, but I also want to store delimiters. My delimiters are ()+-*/ So for example, if I had a string 26+78(12*23)-16 I want to get 26 + 78 ( 12 * 23 ) - 16 each line as a separate array element. I think you can not use split function to achieve this. However, my trial with string-tokenizer also failed. How can I achieve this? 回答1: I wouldn't answer if it wasn't saturday night here: String s1 = "26+78(12*23)-16"; for(String s: s1

问题 After reading all related threads i can not find anything that shows regex that is capable of extracting a full json object from within html content so im hoping someone can help me get the right regex to resolve the issue.

问题 I currently have a string similar to the following: str = 'abcHello Wor=A9ld' What I want to do is find the 'abc' and '=A9' and replace these matched groups with an empty string, such that my final string is 'Hello World'. I am currently using this regex, which is correctly finding the groups I want to replace: r'^(abc).*?(=[A-Z0-9]+)' I have tried to replace these groups using the following code: clean_str = re.sub(r'^(abc).*?(=[A-Z0-9]+)', '', str) Using the above code has resulted in:

问题 Hi i'm actually trying replacing all the NON-alphanumeric chars from a string like this: mb_ereg_replace('/[^a-z0-9\s]+/i','-',$string); first problem is it doesn't replaces chars like "." from the string. Second i would like to add multybite support for all users languages to this method. How can i do that? Any help appriciated, thanks a lot. 回答1: Try the following: preg_replace('/[^\p{L}0-9\s]+/u', '-', $string); When the u flag is used on a regular expression, \p{L} (and \p{Letter} )
