Hi monks, I have one XML file like this

<datainfo>
<data>
<number>12</number>
<branch>electronics</branch>
<details>
.......
</details>
</data>
<data>
<number>23</number>
<branch>computers</branch>
<details>
.......
</details>
</data>
<data>
<number>12</number>
<branch>science</branch>
<details>
.......
</details>
</data>
</datainfo>
[download]

I am reading that xml file using XML::LibXML and printing like this

#!/usr/bin/perl
    use warnings;
    use strict;
    use XML::LibXML::Reader;
    my $file="data.xml";
        
    my $reader = XML::LibXML::Reader->new( IO => $file ) or die ("unab
+le to open file");

    while ($reader->nextElement( 'data' ) ) {
  
    my $info = $reader->readOuterXml();      
  }

$all=$all.$info;
}

 print $all;

Above code is not working It printing only <infolist> and </info> its not printing any data between that. I tried to extract data nodes from xml file and eliminate if any duplicate nodes by searching nuber tag and print this information into string.because I need to use this string some other process.

expected output

<datainfo>
<data>
<number>12</number>
<branch>electronics</branch>
<details>
.......
</details>
</data>
<data>
<number>23</number>
<branch>computers</branch>
<details>
.......
</details>
</data>
</datainfo>

Thanks
