DB XML Xpath problem

Hi,

I am evaluating DB XML to see if I can store very large XML files in it
i.e. total size of data could be several hundred megabytes.

I have so far written some code to break up a large file (17 mb) into
smaller ones and link them using Xlink.

I have been able to load these files into a single container using DB
XML but when I try to perform any query on them I get the following
message:

BDB XML: Optimizer - Started parse

BDB XML: Optimizer - Finished parse, time taken = 30.856ms

BDB XML: Query - Starting query execution

Error executing query: com.sleepycat.dbxml.XmlException: Error: An
attempt was made to perform an axis step when the Context Item was not
a node [err:XPTY0020], errcode = XPATH_EVALUATION_ERROR

I am pretty sure my XML data is ok and I don't understand why the Xpath
part of the query should fail the node test.

Hope someone out there has some ideas?

thanks,
Ryan.

Ryan,

Please provide an example of a query that fails, along
with a snippet of code that calls the query.
Send to me directly, as I do not read this newsgroup on a
regular basis.

This sort of question is usually better handled by the BDB XML
mailing list -- xml@sleepycat.com

Regards,

George
