in thread how to update an xml file by read data from csv file

If it doesn't have the container closing tags then it won't be valid XML (which is certainly possible for a config file, though kind of rude of them to do it that way). No decent XML generator will let you do that. A straightforward way to remove them is to do something like:

$mycontainerless=$tree->as_XML(); $mycontainerless=~%</container>%%gi;

before you write it to the file.

    Thanks bitingduck. i tried the why you said above but seems some error while running the script. not able to resolve the error. can you please advise where am doing wrong. Main script :
    #!/usr/bin/perl use warnings; use strict; use Text::CSV; use XML::TreeBuilder; use Data::Dumper; my $xmlbase='original.xml'; my $paramsfile = 'params.csv'; my $mycontainerless; # the list of tags filled from the csv file my @taglist=qw(name protocol host commandline); # this is the part that repeats, so we break it out separately # the tags that get filled from the CSV file are left empty my $connection= <<END <connection type="PuTTY" name="WSSS"> <connection_info> <name></name> <protocol></protocol> <host></host> <port>22</port> <session>Default Settings</session> <commandline></commandline> <description /> </connection_info> <login> <login /> <password /> <prompt /> </login> <timeout> <connectiontimeout>1000</connectiontimeout> <logintimeout>750</logintimeout> <passwordtimeout>750</passwordtimeout> <commandtimeout>750</commandtimeout> </timeout> <command> <command1 /> <command2 /> <command3 /> <command4 /> <command5 /> </command> <options> <loginmacro>False</loginmacro> <postcommands>False</postcommands> <endlinechar>10</endlinechar> </options> </connection> END ; open (my $resultfile, '>>', 'resultxml.xml') or die "Can't open file: +$!"; #this is the wrapper my $config= <<END <?xml version="1.0" encoding="UTF-8"?> <!-- The following lines can be modified at your own risks. --> <configuration version="0.2.1.4" savepassword="True"> <root type="database" name="WSSS" expanded="True"> <container type="folder" name="CM" expanded="True"> <container type="folder" name="1-AD/M" expanded="True"> </container> </container> </root> </configuration> END ; #start an xml structure with the outer wrapper my $tree=XML::TreeBuilder->new(); $tree->parse($config); # find the insert location my $container=$tree->look_down("_tag"=>"container", "name"=>"1-AD/M"); my $csv=Text::CSV->new(); open my $fh, "<:encoding(utf8)", $paramsfile or die "$paramsfile: $!"; # loop through the lines of the CSV and copy the connection structure +into # the wrapper with the updated values while(my $row=$csv->getline($fh)){ my $contree=XML::TreeBuilder->new(); #make an xml structure of th +e connection $contree->parse($connection); $container->push_content($contree); #insert it into the wrapper $contree->attr('name',$row->[0]); #set the name attribute $container->push_content("\n "); #make it a little prettier my $index=0; for my $tagname(@taglist){ #loop through the columns my $tag=$contree->look_down('_tag'=> $tagname); $tag->push_content($row->[$index++]); } } #print '<?xml version="1.0" encoding="UTF-8"?>'."\n"; print $tree->as_XML(); $mycontainerless=$tree->as_XML(); $mycontainerless=~%</container>%%gi; print $mycontainerless; print $resultfile '<?xml version="1.0" encoding="UTF-8"?>'."\n"; print $resultfile $tree->as_XML(); close($resultfile);
    Error :
    >perl xml.pl Bareword found where operator expected at xml.pl line 98, near "%%gi" (Missing operator before gi?) Operator or semicolon missing before %gi at xml.pl line 98. Ambiguous use of % resolved as operator % at xml.pl line 98. syntax error at xml.pl line 98, near "%%gi" Execution of xml.pl aborted due to compilation errors.
    line number 98 is :
    $mycontainerless=~%</container>%%gi;

      I left out an 's'

      $mycontainerless=~s%</container>%%gi;
        Thank you very much. It worked.
