Hello monks I am trying regular expression to match a string which is given by 
17-08-2010 10:57:22  141-9997  Critical  "OEM:imst2k19:4"

[download]
i use reg exp like this 
if ($var  =~ /^((0[1-9]|[12][0-9]|3[01])-(0[1-9]|1[012])-(20)?\d\d\s\w
+)/)  {

}

I am matching string starting with date in DD-MM-YYYY format and any space and a word character following that.

Now I want to put some more restriction that this string should contain something or nothing in double quote in the end. i.e string starting with date then white space then some characters then ending with double quotes where something or nothing can be withing double quotes eg. "OEM:imst2k19:4" or ""

How existing reg exp can be modified?
