Hi Monk, I have a file of the following content and structure: 

===============================================
// 1st commented line
//second commented line 
// timescale 1ns /5 ns
 
timescale 1ns/4ns  //this comment should also be ignored

module modulename1 (a b c )

some lines.... 
some lines ...


//third commented line 
//fourth commented line 

timescale 3ns/5ns
module modulename2 (p q r)

some lines ...

//fifth comment
//timescale 4ns/5ns

timescale 1ns/3ns 

module modulename3 (m n p )

some line ...

================================================

In this above file structure '//' is used for commenting a line which will be ignored for parsing. I need to parse this above file so that I can extract the timescale value corresponding to each modulename. For example, modulename1 has 1ns/5ns as its timescale, modulename2 has 3ns/5ns and so on. Also the comments after the timescale value will be ignored as mentioned above. The problem being is the timescale value for a particular module is appearing above the module declaration in the file. Please help me in getting the timescale value corresponding to each modulename. Thanks.
