Sending the XML header and script body
After the connection is established, the first line of script sent must be an XML document header, which
tells the device's HTTPS Web server that the following content is an XML script. The header must match the
header used in the example exactly. After the header has been completely sent, the remainder of the
script can be sent. In this example, the script is sent all at once. For example:
# usage: sendscript(host, script)
# sends the xmlscript script to host, returns reply
sub sendscript($$)
{
my $host = shift;
my $script = shift;
my ($ssl, $reply, $lastreply, $res, $n);
$ssl = openSSLconnection($host);
# write header
$n = Net::SSLeay::ssl_write_all($ssl, '<?xml version="1.0"?>'."\r\n");
rint "Wrote $n\n" if $debug;
# write script
$n = Net::SSLeay::ssl_write_all($ssl, $script);
print "Wrote $n\n$script\n" if $debug;
$reply = "";
$lastreply = "";
