I build a small parser to create your perl structure from your file. A part of this is a escape function, that would escape special chars in s///.

The parsing is done specially by the parse.

#!/usr/bin/perl -w use strict; use Data::Dumper; sub escape { my $str=shift; $str=~s/\\/\\\\/g; $str=~s/\[/\\[/g; $str=~s/\]/\\]/g; $str=~s/\(/\\(/g; $str=~s/\)/\\)/g; $str=~s/\{/\\{/g; $str=~s/\}/\\}/g; $str=~s/\^/\\^/g; $str=~s/\//\\\//g; $str=~s/\+/\\\+/g; $str=~s/\-/\\\-/g; $str=~s/\$/\\\$/g; $str=~s/\&/\\\&/g; $str=~s/\*/\\\*/g; $str=~s/\|/\\\|/g; $str=~s/\?/\\\?/g; return $str; }; sub parseoptions { my $options=shift; my @opts=(); $options=~s/\s+$//; for my $opt (split /\n/, $options) { $opt=~/^\s*(\w+)\s+(.*)$/; my $data={name=>$1, content=>$2}; unshift @opts, $data; } return \@opts; } sub parse { my $lookat=shift; my @struct=(); while ($$lookat=~/^\s*(\w+)\s+(\w+)?\s*{/) { my $data={type=>$1,name=>$2}; my $str=escape($&); $$lookat=~s/^$str//; if ($$lookat=~/^[^}]+{/) { $data->{content}=parse($lookat); $$lookat=~s/^\s*}//; } else { ($data->{content})=$$lookat=~/^\s*([^}]+)\s*}/ +; my $str=escape($&); $$lookat=~s/^$str//; if ($data->{type} eq 'single') { $data->{content}=parseoptions($data->{ +content}); } } unshift @struct, $data; } return \@struct; } my $quest=""; while (my $line=<>) { $line=~s/^\s+/ /g; $quest.=$line; } my $struct=parse(\$quest); print Dumper($struct);

Hope this helps.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
