need module to be built to import real time xml feed simple

need an easy to use module to be built to import real time xml feed simple api into a shopping cart in joomla (virtuemart, zen cart, xcart, oscommerce any of main carts) we are running a linux based server and joomla 1.5 the module needs to send queries real time as an http post and display information into shopping cart The XML Data Stream is an Internet-based interface that uses XML structured queries to obtain information. XML Data Stream is a full-featured API designed to direct access to the product database in order to implement customized end-user search tools or internal applications. using the XML Data Stream is to create a pipe to be used for communication with the servers. Each request is made using a standard HTTP POST with the request data being contained in an XML structure as the request’s content. You can use any programming language and component that you wish to implement the connection to the server. Implementations are possible with ASP, Visual Basic, Perl, C/C++, Java, and any other language that is capable of creating a socket connection. Connections are made over the standard HTTP port (port 80) using an unencrypted connection or via the standard HTTPS port (port 443) using an encrypted connection. Because your user ID and password are sent across the Internet with each request, we strongly recommend using a secure SSL connection over port 443. there is also a user name and password. we also have support and can have any questions answered directly from the data feed supplier looking for someone good and reliable we also have other jobs that need to be completed if we find the right person Thank you in advance
