Hello Monks,

I have a tag like <img src="path of image"/> in a xml document. I want to change the name of the attribute using XML::Twig.

I tried like the following:-

    for $item ($twig->get_xpath("//img"))
    {
    $item->change_att_name('src', 'links') 
    }

But I didn't get result. pls help me

You're doing something else wrong then. This works just fine. `#!/usr/bin/env perl use strict; use warnings; use XML::Twig (); my $twig = XML::Twig->new; $twig->parse( qq{<img src="/foo/bar.jpg" />\n} ); for my $img ( $twig->get_xpath( "//img" ) ) { $img->change_att_name( 'src', 'links' ); } $twig->print; exit 0; __END__ ## Outputs: <img links="/foo/bar.jpg"/>` [download]	[reply] [d/l]

It worked when I tried it (see below). Does `$twig->get_xpath("//img")` return any result? What I tried: `#!/usr/bin/perl use strict; use warnings; use XML::Twig; my $twig= XML::Twig->parse( \*DATA); for my $item ($twig->get_xpath("//img")) { $item->change_att_name('src', 'links') } $twig->print; __DATA__ <html> <body> <p><img src="foo"/></p> <p><img src="bar"/></p> </body> </html>` [download]	[reply] [d/l]
