ios - regEx expression for detecting javascript call function -


for example, there @"javascript:viewdata(3713, 'a', 89360)" string.

i want extract 3713, , 89360 string.

for java, "viewdata\(([^\(]*),[\s\s]\'([^\(]*)\',[\s\s]([^\(]*)\)" can extract strings successfully.

however, couldn't extract them in ios objective-c.

my code below:

nsstring *searchedstring = @"javascript:viewdata(3713, 'a', 89360)"; nsrange   searchedrange = nsmakerange(0, [searchedstring length]); nsstring *pattern = @"<here pattern needed>"; nserror  *error = nil; nsregularexpression* regex = [nsregularexpression regularexpressionwithpattern:pattern options:0 error:&error]; nstextcheckingresult *match = [regex firstmatchinstring:searchedstring options:0 range:searchedrange];

then matched string as:

[searchedstring substringwithrange:[match rangeatindex:1]] .. , on.

how can set pattern?

basically regex pattern supposed work in objective-c, too.

however have escape backslashes:

nsstring *pattern = @"viewdata\\(([^\\(]*),[\\s\\s]\\'([^\\(]*)\\',[\\s\\s]([^\\(]*)\\)";

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
