S3 PUT Bucket to a location endpoint results in a MalformedXML exception

Question

I'm trying to create an AWS s3 bucket using libCurl thusly:

Location end-point curl_easy_setopt(curl, CURLOPT_URL, "http://s3-us-west-2.amazonaws.com/");

Assembled RESTful HTTP header:

PUT / HTTP/1.1

The body contains the bucket configuration http://s3.amazonaws.com/doc/2006-03-01/">us-west-2

I get the following exception back. MalformedXMLThe XML you provided was not well-formed or did not validate against our published schema

I've been able to carry out the same operation through the aws cli.

Things I've also tried.

1) In the xml, used \ to escape the quotes (i.e., xmlns=\"http:.../\").

2) Not providing a CreateBucketConfiguration ("Although s3 documentation suggests this is not allowed when sending the request to a location endpoint").

3) A get service call to the same end point is listing all the provisioned buckets correctly.

Please do let me know if there is anything else I might be missing here.

Ok, the problem was that I was not transferring the entire xml across as was revealed by a wireshark trace. Once I fixed it, the problem went away.

Btw... escaping the quotes with a \ works but the & quot ; does not.
