正则：如何将注释下对应的代码取出来

Python code

s = '''/*--第一个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB1')  )drop table [dbo].[d_BB1]GO/*--第二个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB2')  )drop table [dbo].[d_BB2]GO/*--第三个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB3')  )drop table [dbo].[d_BB3]GO/*--第四个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB4')  )drop table [dbo].[d_BB4]GO'''findkey0 = ('/[*]--.*?--[*]/')findkey1 = ('/[*]--.*?--[*]/[\s\S]*?/[*]--.*?--[*]/')findkey2 = ('--[*]/[\s\S]*?/[*]--')rs =  re.findall(findkey1,s,re.I)for r in  rs:    print r

运行结果是

Python code

/*--第一个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB1')  )drop table [dbo].[d_BB1]GO/*--第二个sql  --*//*--第三个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB3')  )drop table [dbo].[d_BB3]GO/*--第四个sql  --*/

怎么把每个注释下的代码取出来，要包含对应的注释

[解决办法]

Python code

#!/usr/bin/env pythonimport res = '''/*--第一个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB1')  )drop table [dbo].[d_BB1]GO/*--第二个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB2')  )drop table [dbo].[d_BB2]GO/*--第三个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB3')  )drop table [dbo].[d_BB3]GO/*--第四个sql  --*/if exists (select * from dbo.sysobjects where id = object_id('d_BB4')  )drop table [dbo].[d_BB4]GO'''pat = re.compile(r'(/\*.*?)(?=/\*|$)', re.S | re.U)rs = pat.findall(s)if rs:    for line in rs:        print line
