Newbie mistake, but I can't find it, help appreciated on XML import

Question

I'm sure I'm making a newbie mistake but I can't find it. If someone could tell me what I'm doing wrong I would appreciate it.
Step one works (i'm logged as user xdb on the database):
SQL*Plus: Release 10.1.0.2.0 - Production on Wed Dec 20 13:47:53 2006

7 ignore :=dbms_xdb.createFolder('/datamart/CustomerCare/xml');

Step two works, where I drag and drop via Windows Explorer my xsd file into http://d01db:8085/datamart/CustomerCare/xsd. It has a size of about 7k or so. Again, when connecting to the respository with Windows Explorer, I'm logging in as xdb.
Step three works, where I register the schema that I just put into the XML repository. Still logged into SQLPlus as xdb.

Step four is where I have problems. I'm using Windows Explorer to drag and drop an XML instance document into http://d01db:8085/datamart/CustomerCare/xml while logged into the repository as xdb.
Here's some of the test file that I'm using.
<?xml version="1.0" standalone="no"?>
<StetonAuditResults xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/xdb/Steton.xsd">
     <Control>
          <ResultCount>112</ResultCount>
     </Control>
</StetonAuditResults>
Note, the test XML file is 427k in size and I can't post it here. There is a lot of data between the </Control> tag and the </StetonAuditResults> tag.
During the Drag and Drop I get the message "An error occured copying some or all of the selected files."
My first suspicision was that the XML document failed validation. So I changed the namespace line to
<StetonAuditResults xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="H:\StetonCustomerCare\Steton.xsd">
I then started Altova's XMLSpy and the XML document is well formed and it validates.
I then changed the namespace line in the XML document to
<StetonAuditResults xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
and I could use Windows Explorer to drag and drop the file into the XML DB respository of http://d01db:8085/datamart/CustomerCare/xml, but this version doesn't shred the XML document into the SQL tables that I need.
I then deleted the file from the repository.
I then changed the namespace line in the XML document to <StetonAuditResults xmlns:xdb="http://xmlns.oracle.com/xdb" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Steton.xsd">
because someone told me to, and because I have seen an FAQ in this forum suggest this approach. I can copy using Windows Explorer into the http://d01db:8085/datamart/CustomerCare/xml. However, the file size via Windows Explorer is 427kb. Also "select count(*) from STETONAUDITRESULTS;" returns zero.
What am I doing wrong?
My background, I'm not an Oracle DBA, but I can code SQL select statements. So if I need to do something involving Oracle DBA privileges, please document it well. I will have to get the DBA's involved.
My goal is import this XML file so that I can use it as a feed for a datamart. The first XML file in text format is 27mb.
Thanks again for reading this far.

Answer 1

I guess you have a namespace issue...(schema registered is not the same as the layout in your XML instance/doc, therefor will not be inserted). You have access to the XDB account...thats all you need (more then enough, i mean, you don't need dba privs).
on the FAQ Mark explains...
Why is the size of my XML document 0 bytes when viewed via HTTP or FTP ?
Posted: Sep 1, 2006 6:07 AM in response to: mdrake in response to: mdrake      
When a schema based XML is loaded into the XML DB repository via HTTP, FTP or dbms_xdb.createResource() the document is converted from a textual serialization of XML into a series of objects. At this point the size of the document becomes (a) meaningless and (b) difficult / expensive to calculate.
The first question is what is meant by the size of the document once it has been stored using object-based persistence ? There are two possibilities
(1) The number of bytes used the text serialization of the XML document.
(2) The number of bytes required to store the internal object representation of the document. In this case the does the size include the bytes used for keys, refs indexes, etc ?
Since (1) would be expensive to maintain as the document is updated (particularly in the case of partial updates) and (2) is expensive to calculate on a document by document basis, XML DB shows the size of all schema based XML documents as 'zero' bytes.
Note that this also applies to the size of the registered version of XML Schema documents, which can be found in the folder tree /sys/schemas.
If a schema based XML document is loaded into the repository and does not appear as 0 bytes long when viewed via HTTP or WebDAV this means that XML DB was unable to identifiy the XML schema the XML document is associated with.
Note that immediatlely after uploading a document in Windows Explorer using the WebDAV protocol the size of the document will be non-zero, since the original size is cached by the Microsoft WebDAV client. However once a refresh of the folder is performed in Windows Explorer the size should be shown as zero if the document was recognized as a schema based document.
