Parsing a file

[amittewarii]

Hello Everybody ,
I need help in parsing the given file ,

############### ############### ############### ############### #####
<sample_cfg : 00FF_F000>
#f_name bit_pos reset_val readable? writeable? special
sample_set 31:16 0000 y y -
sample_status 15:0 FFFF y n W1C
</sample_cfg>


<sample_int : 00FF_F100>
#f_name bit_pos reset_val readable? writeable? special
sample_set 0 0 y n W1C
sample_status 1 0 y n W1C
</sample_int>

<sample_int_mas k : 00FF_F200>
#f_name bit_pos reset_val readable? writeable? special
sample_set 0 0 y y -
sample_status 1 0 y y -
</sample_int_mask >


The data has to be extracted first and then formed in the form of a "Hash of Hash of Hash "

<sample_cfg : some value > is the register name
which has 2 function sample_set & sample_status . Each of this function has 5 fields . We need to parse them out and fill them in a HoHoH so that they could be represted in the form of a tree .

Regards ,
Amit

Well, as far as the parsing is concerned, the obvious (i.e., off the top of my head and not tested :-) ) would be something like:

[code=perl]...
open SMPL, "<sample_cf g" or die "Could not open file for reading: $! \n";
while ( <SMPL> ) {
if ( /^sample_/ ) {
($f_name, $bit_pos, $reset_val, $readable, $writeable, $special ) = split;
.... # now that the line is parsed, do whatever, e.g., put it into your HoHoH
}
}
close SMPL;[/code]

Note that the split function defaults to splitting the $_ (line just read) at spaces, which looks like exactly what you want to do.

HTH,
Paul

I see in your first thread in this forum you posted some code so I assume you will have some code written already that you have been working with. Please post that code.
