So, it turns out inserting a new node into an existing xml list is not as easy as I thought. I'm sure I'm missing something but been tinkering with this for quite some time now so I ask you for some guidance.

In short, I'm using a file as a base model which is being read in that looks similar to this.

<top>
    <nodes>
      <node>
        <label>Office</label>
          <node>
            <label>1st Floor</label>
          </node>
          <node>
             <label>2nd Floor</label>
          </node>
      <node>
    <nodes>
</top>

Say I want to add something to the 1st floor like this. <node> <label>10.1.1.1</label> </node> I've gone through many different variations so I'll post one of them as the closest I can come is appending it to the end and not to the floor I want. 
#!/usr/bin/perl
use XML::LibXML;

$filename = "Office.xml";
my $floor   = '1st Floor';
my $bldg = "Building A";
my $parser = XML::LibXML->new();
my $doc = $parser->parse_file("$filename") or die;
my $root = $doc->getDocumentElement();
my $parent = $doc->documentElement;
my $newnode = $doc->documentElement;

my $query  = "//node[label = '$bldg']/node[label = '$floor']/label/tex
+t()";

if(my($node)  = $doc->findnodes($query))
{
 my $new_element= $doc->createElement("IP");
 $new_element->appendText('10.1.1.1');
 $newnode = $parent->addSibling($new_element);

 print $newnode -> toString;
}

Can someone please help?
