Question

I am parsing binary file. File size can be large. I want to search a some pattern in that file. the string is

anynumber 0 obj<< any
alpha,symbol,digit…anything
>>endobj

Bold text indicates compulsory string.
So, My QUESTION is – should I do it by regular expression or search it by coding. After that I want to store it in a dictionary.
If regular expression then what it be? what is the fastest way?
I am using VS-2005.

Answer 1

\d+0 obj\<\<.*\>\>endobj

\d    – decimal digit
+     – 1 or more
\<    – < should be treated as a literal
.     – any character
*     – 0 or more
>    – > should be treated as a literal
