The invention discloses a combined type data cutting method based on regular expression and separators. The method comprises the following steps: a) reading a log file; b) recognizing and extracting an event in the log file according to a timestamp or a start symbol; c) extracting data of the extracted event content according to the fixed separator or regular expression way; selecting a plurality of preset character strings by the step b) as the start symbol, and converting the plurality of preset character strings into a plurality of regular expressions, traversing each line of log data, orderly matching with each regular expression. Through the adoption of the combined type data cutting method based on regular expression and separators provided by the invention, the different cutting ways are used according to different event types, each cutting way is corresponding to a log within the range, and the character string operation is provided through each way, thereby satisfying the fast recognition cutting of various complex logs, the method is simple and easy to use, and good in expansibility.
