Abstract

The invention relates to a string trimming method and a string trimming device. The method comprises the following steps of: replacing each of the operation relationship symbols in the first chargingexpression with a character corresponding to the same, and acquiring the converted second charging expression; receiving a trimming instruction, screening and deleting characters corresponding to theoperation relationship symbols logically related to the first accounting charge ID in the second charging expression and the first accounting charge ID according to the preset rule, and acquiring a third charging expression; and inversely transforming the characters corresponding to the operation relationship symbols in the third charging expression according to the preset order, and acquiring a fourth charging expression. Through the above manner, the accounting charge ID to be deleted in the charging expressions may be quickly deleted without affecting the logical relationship of the entireexpression.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a string trimming method and device. Background technique [0002] Since the long-distance and roaming requirements have been cancelled, the existing charging and charging methods still use the previous charging methods. Now it is necessary to remove the implementation of long-distance and roaming in billing tariffs. That is, the sub-accounting tariff IDs for long-distance and roaming in the tariff expression need to be trimmed. For tariff expressions such as: [0003] mut(add(mut(add(mut(BDp0,BD10),mut(CTp10,CTz10)),mut(MY20,MYb20)),L2f100f),mut(mut(add(L3f30e,GS001),mut(Glx0,Gxl0 )), mut(BDb0, DX10))), because there is a logical relationship between each sub-booking fee in the expression, "and-and" or "or-mut", one of the sub-books in the expression should be removed Account fee ID (if you need to remove the caller ID: Glx0), and you want not to affect the logical...
