Upload an xls file to google docs with cURL call only(no Gdata API)

Hi,

Is there any way to upload an xls file to google docs using only cURL call through php.
I have tried with Gdata but unfortunately that didn't worked
(giving me an error uploaded file cannot be imported)

here is the code with with I am trying with but its giving me an error 411, that's an error Post Request requires a header Content-length
though I have set the Content-Length Header

$xml='<?xml version="1.0" encoding="UTF-8"?>
<atom:entry xmlns:atom="http://www.w3.org/2005/Atom">
<atom:category scheme="http://schemas.google.com/g/2005#kind"
term="http://schemas.google.com/docs/2007#spreadsheet" label="spreadsheet"/>
<atom:title>example spreadsheet</atom:title>
<docs:writersCanInvite value="false" />
</atom:entry>';


$headers=array(
"Authorization:GoogleLogin auth=". $auth,
"Content-Type: application/atom+xml",
"Content-Length:". strlen($xml),
"Slug:test"
);
// Make the request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://docs.google.com/feeds/documents/private/full");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER , 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
$response = curl_exec($ch);
