Hi Monks,

I think that my brain has reached its capacity and I need help for a algorithm I am not able to implement. It is very important!

I have to parse a xml file (model.xml). In this file, there is a nested repetitive motif. For instance,

<fixe>
<aaa></aaa>
<bbb></bbb>
<bbb></bbb>
<ccc></ccc>
</fixe>
[download]

I mean in each element (<aaa></aaa>, <bbb></bbb>) I can find the same structure recursivly, without number limitation. (the name of <aaa></aaa> etc. element is random, only the <fixe> has a constant name).

<fixe>
    <aaa>
        <fixe>
            <eee/>
            <bbb/>
            <bbb/>
            <ccc>
                <fixe>
                    <aaa/>
                    <eee/>
                    <bbb/>
                    <fff/>
                    <ccc/>
                </fixe>
            </ccc>
        </fixe>
    </aaa>
    <bbb/>
    <bbb/>
    <ccc/>
</fixe><br />

I use DOM with the XML::LibXML API. The goal of my script is to remove the <fixe></fixe> elements and according to parameters (A number od dupplication and name of element) to dupplicate the node. for example, name = eee and number = 4, the xml would become.

    <aaa>
            <eee/>
            <eee/>
            <eee/>
            <eee/>
            <bbb/>
            <bbb/>
            <ccc>
                    <aaa/>
                    <eee/>
                    <eee/>
                    <eee/>
                    <eee/>
                    <bbb/>
                    <fff/>
                    <ccc/>
            </ccc>
    </aaa>
    <bbb/>
    <bbb/>
    <ccc/>

I have done this script which remove the element "fixe"

#!/usr/bin/perl -w
use strict;
use XML::LibXML;

my $parser  = XML::LibXML->new();    
my $doc = $parser->parse_file("model.xml") or die "cannot open xml fil
+e: $!";    

my $node = $doc->getDocumentElement();
my @dc = $child[0]->getElementsByTagName('descriptor');    

foreach my $descr (@dc) {
            foreach my $elt ($descr->childNodes())
             {
                next unless $elt->nodeType() == 1;      #to avoid text
+ nodes                                                 
                $descr->addSibling($elt);
               }
               my $parent = $descr->parentNode;            
               $parent->removeChild($descr);
}

print $child[0]->serialize;

for the duplication, I have tried to use the addSibling function with a foreach but I got an error, I try also the cloneNode and insertBefore function but no way...

Any help would be very appreciated.
