matlab中用正则表达式如何取两个字符串之间的字符串

例如‘floor_num":2bsaubakejdacbnklsfloor_num":3‘，我要取bsaubakejdacbnkls，节点是在floor_num":2和floor_num":3之间

Answer 1

clear;clc

s='fafw34rfdfloor_num":2bsaubakejdacbnklsfloor_num":3asdf23tfloor_num":4stsmnw54dgfloor_num":212floor_num":234floor_num":3';

regexpi(s,'(?<=floor_num":2).*?(?=floor_num":3)','match')

 

ans = 

    'bsaubakejdacbnkls'    '12floor_num":234'

追问

我这可能需要匹配的太多了，一直没有出结果，就给你吧
