我尝试使用正则表达式从下面的日志中捕获数据组。模式是
<item> : <key> = <value> , <key> = <value>, ..., <key> = <value>
([#\w\d]*?)[\s]*=[\s]*([.\w\d]*)可以抓包<key>和组<value> 但我想捕获 <item>也分组，所以我将以上内容分组并使用 {n} 重复。
([\w]*):([\s]*(([#\w\d]*?)[\s]*=[\s]*([.\w\d]*)),*){1,}
20141207,07:15:52,0,>>RATIO: casher#=30, Value=2.579,Units=ratio,Error=N 20141207,07:15:52,0,>>RATIO: casher#=31, Value=4.509,Units=ratio,Error=N 20141207,07:15:52,0,>>RATIO: casher#=32, Value=3.735,Units=ratio,Error=N 20141207,07:15:52,0,>>RATIO: casher#=33, Value=2.401,Units=ratio,Error=N
20141207,07:15:52,0,>>CUSTOMER: casher#=30, Value=50,Units= count 20141207,07:15:52,0,>>CUSTOMER: casher#=31, Value=6,Units= count 20141207,07:15:52,0,>>CUSTOMER: casher#=32, Value=88,Units= count 20141207,07:15:52,0,>>CUSTOMER: casher#=33, Value=33,Units= count
显然结果不是预期的那样。谁能给我一些提示？我最终使用 python 转换为代码。谢谢。
请您参考如下方法:
(?<=>>)(\w+):|([\w#]+)\s*=\s*(\S+?)(?:,|\s)
试试这个。抓取捕获。查看演示。
