Regex expression in java remove first value in csv -

-

I have a CSV file that looks like this: 

  12,2014- 10 - 09 06: 00: 00,2014-10-09 06:15:00, "", "", "", "123,456", "", "9,999", "", ""  < / Pre>  
  string test = rowData.replaceAll ("([0- 9]), ([0-0] 9])," $ 1 $ 2 " I'm not sure that this is the best way to do this (the opinion is my problem is to remove the first value before commas. Needed, so basically my output should be something like this  
  Orig: 12,2014-10-09 06:00: 00-10-10 06:15:00, "", "", "", "123456,", "", "9,999", "", "" requirement: 2014-10-09 06: 00: 00,2014-10-09 06:15:00, ,, 123456, 99 99,   
 I'm not sure that doing this requires another regex because I do not know how OK Or use something like last time or the first index to remove the fist value of a comma? Thanks  
 Edit: I saw that I can not use ([0- 9]), ( [0- 9]) The reason it also removes a comma for the timetable: (.) ​​The correct question is how to replace the CSV: 1. First value 2. Quotation 3. Between the digits and quotes Cama   
 
 
 your expectations You can do something like this to match the output of the output  
  string str = "12,2014-10-09 06: 00: 00,2014-10- 09" + "06: 15:00, \ "\", \ "\", \ "123,456 \", \ "\", \ "9,999 \", \ "\", \ "\" str = str.substring (str.indexOf ( ',') + 1); Str = str.replaceAll ("\" (\\ d +), (\\ d +) \ "", "$ 1 $ 2") .replace ("\", ""); string expected = "2014 -10-09 06: 00: 00,2014-10-09 06:15:00 ,,,, 123456, 9999, "; System Output."  / html>

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
