How to get same input xml file as xml out file

[kiranbk]

i am trying to update xml element value using XML::Simple::XMLin .But when I am again trying to retrive the XML data as it was before using XML::Simple::XMLout.
But finding a deviation in the format can any pls help me out with same xml file structure.

input file:

<NavigationMap> <PageLink> <LinkText/> <url>/ae/index.html</url> <Domain>//www.fedex.com</Domain> <Protocol>UnSecure</Protocol> <Target/> <LinkParams/> </PageLink> <ImageSource alt="FedEx Home">//images.fedex.com/images/c/t1/gh/logo-header-fedex-express.png</ImageSource> </Logo> </NavigationMap>
 

Output file after execute:

<NavigationMap lastId="146"> <Logo> <ImageSource alt="FedEx Home">//images.fedex.com/images/c/t1/gh/logo-header-fedex-express.png</ImageSource> <PageLink> <Domain>//www.fedex.com</Domain> <LinkParams></LinkParams> <LinkText></LinkText> <Protocol>UnSecure</Protocol> <Target></Target> <url>/zw/index.html</url> </PageLink> </Logo> </NavigationMap>
 

Perl code:

$data = $xml -> parse_file($file_in,ForceArray => 1,KeyAttr =>[]);
foreach $TabEle (@{$data->{Logo}}) # retrieving list of values under Tab element
{
        foreach $NameEle (@{$TabEle->{PageLink}}){
        foreach $LinktxtEle(@{$NameEle->{Protocol}}){
        print $LinktxtEle;
        }
 
   }
 }
XMLout($data,rootname => 'NavigationMap',KeyAttr =>[],OutputFile => $file_in,NoSort => 1);    #Writing xml back with updated value.
}
 

Expected result:

<NavigationMap lastId="146"> <PageLink> <LinkText/> <url>/ae/index.html</url> <Domain>//www.fedex.com</Domain> <Protocol>UnSecure</Protocol> <Target/> <LinkParams/> </PageLink> <ImageSource alt="FedEx Home">//images.fedex.com/images/c/t1/gh/logo-header-fedex-express.png</ImageSource> </Logo> </NavigationMap>

The author of the module states:

STATUS OF THIS MODULE

The use of this module in new code is discouraged. Other modules are available which provide more straightforward and consistent interfaces. In particular, XML::LibXML is highly recommended.

The major problems with this module are the large number of options and the arbitrary ways in which these options interact - often with unexpected results.

Patches with bug fixes and documentation fixes are welcome, but new features are unlikely to be added.
