I'm using XML::XPath for a long time to parse xml, now the situation has come to modify the attribute value.

xml is available in a file, it will be very similar to this.

<AppName>

<Action AllDay='1'StartRace='1'/>

<StartPoint AM_PM='AM' Hours='09' Mins='30'/>

<EndPoint AM_PM='PM' Hours='06' Mins='30'/>

</AppName>

I have written a perl script to change the Hours of StartPoint tag,

use strict;
use warnings;
use XML::Twig;

my $fileName = 'Conf.xml'

my $twig = XML::Twig->new(
    twig_roots => { StartPoint => \&ReplaceAtriValue },
    twig_print_outside_roots => 1,
);

sub ReplaceAtriValue {
    my ($twig, $startPoint) = @_;
    if ( '09' eq $startPoint->att('Hours') )
    {
        $startPoint->set_att( Hours => '12');
    }
    $startPoint->print();
}
$twig->parsefile($fileName);

Now $twig has the xml object. If I send this object($twig) to my SetWindow.pm which parse xml using XML::XPath, did not recognize $twig object.

Is there any possible way to convert XML::Twig object to XML::XPath object so that XML::XPath will parse values in the $twig object.

Actually I have using XML::XPath for long back hence I have to send the XML::XPath object to all my own *.pm like SetWindow.pm, at the same time i need to change the values of the attribute of the standard xml before sending to my own PMs.

Thanks in Advance

Any Help is much appreciated

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
