Hi, Monks, See my below simple script. I got to get the data of the section content and I failed to do it when it comes to the multiple lines which are supposed:
DESCRIPTION = {
UK BANK;
UN BANK;
};
The section content is what between section name and section end.
#! /usr/local/bin/perl -sw
BEGIN {
close STDERR and open STDERR, '>./STDERR' or die $!;
}
use Parse::RecDescent;
#use strict;
#use warnings;
$::RD_TRACE = 1;
$::RD_HINT = 1;
#============================================
# GRAMMAR DEFINITION HERE

|{ use Data::Dumper 'Dumper';
print "$_->[0]\n" for @{$thisparser->{errors}};
exit;
}
List: 'SECTION_START'
SECTION_NAME
SECTION_CONTENT(s?)
SECTION_END

SECTION_NAME:
/\w+/ {print "section name is $item[1]\n";}

'SECTION_END' {print "section END is $item[1]\n";}

my $parse = new Parse::RecDescent ($grammar);
my $text = do { local $/; <DATA> };
$parse->Para($text);

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
