下面以测试以aclineStart aclineEnd 的标签为例

分为三步进行操作

具体操作如下

'''

#1  获取acline在本文件里面的lineStart：起始行 lineEnd:结束行

fliePath="黄冈_20191126_235500.CIME"

lineStart, lineEnd = getTagStartEndLineNum(fliePath, aclineStart, aclineEnd)#aclineStart aclineEnd 的标签为例

print(lineStart)

print(lineEnd)

#2 获取acline在本文件里面的lineStart：起始行 lineEnd:结束行 返回的结果

flieList = lineCent(fliePath,lineStart, lineEnd)

print(flieList)

import sqlite3

conn = sqlite3.connect('test.db')

cursor = conn.cursor()

cursor.execute('''create table ACLine(Num varchar(20),mRID varchar(20),name varchar(20),pathName varchar(20),aclnNum integer)''')

#3 返回的结果进行入库操作

for line in flieList:

    AA,A, B, C, D,E = line.split(" ")

    print(AA)

    print(A)

    print(B)

    print(C)

    print(D)

    print(E)

    sql = "insert into ACLine(Num,mRID,name,pathName,aclnNum) values(" + A + "," + B + ",'" + C + "','" + D + "'," + E + ')'

    print(sql)

    cursor.execute(sql)

conn.commit()

conn.close()
