in thread xml::twig delete element

This should do more or less what you want:

use strict; use warnings; use XML::Twig; my %self2pnam; # Self => pnam for all color elements my $twig=XML::Twig->new( # create self2pnam twig_handlers=>{ color => sub { $self2pnam{$_- +>att('Self')}= $_->att( 'pnam'); } }, pretty_print => 'indented', ); $twig->parse(\*DATA); # now we can process the content elements foreach my $content ($twig->root->children( 'content')) { my $box= $content->prev_elt( 'box[@type="text"]'); $content->set_tag( 'updated_tag') ->del_atts ->set_att( Color => $self2pnam{$box->att( 'frameColorID')} +) ; } $twig->print; __DATA__ <document> <root> <box type="text" cont="text" textflowid="rc_u5035" frameColorID="ua +5"/> </root> <content type="text" Self="rc_u5035" id="rc_u5035"/> <header>h3</header> <meta> <color type="colr" clmd="prss" clsp="CMYK" clvl="4_D_0_D_15_D_50_D_0 +" ovrd="norm" atcs="nasp" atvl="0" pnam="Color 04-15M/50Y" edbl="t" r +mbl="t" pvis="t" swID="1f01" Self="uce"/> <color type="colr" clmd="prss" clsp="CMYK" clvl="4_D_0_D_10_D_40_D_0 +" ovrd="norm" atcs="nasp" atvl="0" pnam="Color 05-10M/40Y" edbl="t" r +mbl="t" pvis="t" swID="1f01" Self="ua5"/> </meta> </document>

Re^6: xml::twig delete element

    Thanks for the reply mirod, Is it possible from my method to do like that. i need to get and update the same where i have commented. i need to do like this process a lot with "content" elements. so it would be better i should twig the content and from there i should get whatever i want instead seperate process. it will help me in understand the process also. Please help me.

      It would be very similar: 1 pass to build the %self2pnam map, same as in the code above, except maybe adding a $_->purge at the end of the handler. The second pass would have a handler on content that would do exactly what's in the foreach loop.

      At this point, I believe you have all the elements to write the code yourself.

        i tried but the hash value not passed to the content_handler. how can i do that? I have one more clarification regarding keep_atts_order. i am using keep_att_order=>1 in the twig_handler but it's not kept my all attributes in the same order which i have added like below
        $content->set_atts({bid=>$bidvar, aid=>$aidvar, att=>'', pgnbr=>$pgnbr +var});
