Re^2: Renumbering ID values for XML tags

Thank you for your reply Prasad, I was quite successful in inserting id to the XML file using the XML::Twig. But I do not want the XML to be parsed. My XML file may not be structured. The code I have with me...

#use strict;
use XML::Twig;
my $string = '<xml>This is a stringThis is a stringThis is a string</xml>';
my $twig = new XML::Twig(
twig_handlers => {
p => sub { $_->add_id() },
},
pretty_print => 'indented' #print format
);
$twig->set_id_seed( '' );
$twig->parse($string);
$string = $twig->sprint;
print $string;

Hi rsriram, I think if your XML file is not well-formed you cannot process your file with XML::Twig. Instead you can do using regex. Before that you have to select the required `<p>` for processing id. After selecting required paragraphs `<p>`, you can do something like this. `use strict; use XML::Twig; my $string = '<xml> <p>here the paragraph comes</p> <p>here the paragraph comes</p> <p>here the paragraph comes</p> <p>here the paragraph comes</p> </xml>'; my $i =1; $string =~ s/<p>/'<p id="'.$i++.'">'/egs; print $string; output: ------- <xml> <p id="1">here the paragraph comes</p> <p id="2">here the paragraph comes</p> <p id="3">here the paragraph comes</p> <p id="4">here the paragraph comes</p> </xml>` [download] Prasad	[reply] [d/l] [select]

Hi rsriram,

I think if your XML file is not well-formed you cannot process your file with XML::Twig. Instead you can do using regex. Before that you have to select the required  for processing id.

After selecting required paragraphs , you can do something like this.

use strict;
use XML::Twig;

my $string = '<xml>
<p>here the paragraph comes</p>
<p>here the paragraph comes</p>
<p>here the paragraph comes</p>
<p>here the paragraph comes</p>
</xml>';

my $i =1;

$string =~ s/<p>/'<p id="'.$i++.'">'/egs;

print $string;

output:
-------
<xml>
<p id="1">here the paragraph comes</p>
<p id="2">here the paragraph comes</p>
<p id="3">here the paragraph comes</p>
<p id="4">here the paragraph comes</p>
</xml>
