# First, let's create the following XML:

#   <FatturaElettronicaHeader>
#     <DatiTrasmissione>
#       <IdTrasmittente>
#         <IdPaese>IT</IdPaese>
#         <IdCodice>12345678</IdCodice>
#       </IdTrasmittente>
#     </DatiTrasmissione>
#   </FatturaElettronicaHeader>

$xml = chilkat::CkXml->new();
$xml->put_Tag("FatturaElettronicaHeader");
$xml->UpdateChildContent("DatiTrasmissione|IdTrasmittente|IdPaese","IT");
$xml->UpdateChildContent("DatiTrasmissione|IdTrasmittente|IdCodice","12345678");

# Now insert a new node to get this XML:

#   <FatturaElettronicaHeader>
#     <DatiTrasmissione>
#       <IdTrasmittente>
#         <IdPaese>IT</IdPaese>
#         <NewTag>Content</NewTag>
#         <IdCodice>12345678</IdCodice>
#       </IdTrasmittente>
#     </DatiTrasmissione>
#   </FatturaElettronicaHeader>

# xT is a Xml
$xT = $xml->FindChild("DatiTrasmissione|IdTrasmittente");
$index = $xT->TagIndex("IdPaese");
if ($index < 0) {
    print "nothing found at the given tag." . "\r\n";
    exit;
}

# x1 is a Xml
$x1 = $xT->NewChildAfter($index,"NewTag","Content");

# Show the resulting XML.
print $xml->getXml() . "\r\n";
