Your XML is not set up correctly. When I used your XML I got 10 records in the cursor one for each node in the xml. The XML document needs one node as the top level node defining the XML document and then it needs nodes that define each record and within each record it needs nodes for each field. You can modify your XML to the following to get what you are expecting;

<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
