PM10423: INCORRECT RESULT FOR BASE-URI OR DOCUMENT-URI FUNCTION IF INPUT IS A STREAMSOURCE WHOSE SYSTEM ID IS A RELATIVE URI

APAR status

• Closed as program error.

Error description

• If the base-uri or document-uri function is used in an XSLT
  stylesheet or an XQuery or XPath expression, and the argument
  is a node in an input document that was created using a
  StreamSource object with a system ID that was a relative URI,
  the result of the function should be the absolute URI to which
  the processor resolved the relative URI.  The processor is
  instead returning the original relative URI.

  *                      an XQuery expression or an XPath        *
  *                      expression is supplied using a          *

  *                      be specified on the StreamSource        *
  *                      object.  If the value of the system     *

  *                      document-uri functions should return    *
  *                      the absolute URI, but the processor     *
  *                      is actually returning the relative      *
  *                      URI reference, if such was specified    *
  *                      on the StreamSource.                    *

  ****************************************************************
  If the system ID set on a StreamSource is a relative URI or a
  file system path, the processor resolves the URI to an
  absolute URI using the setting of the user.dir Java system
  property in order to retrieve the XML input.  However, the
  processor is storing the value of the original system ID as
  the base URI of the document for use in the base-uri
  and document-uri functions.  This causes the result of these
  functions to return the incorrect value - the original
  relative URI.
  

Problem conclusion

• The problem was fixed by changing the processor to store, with
  the associated XML input in memory, the value of the absolute
  URI to which the original relative URI reference was resolved.
  This ensures the processor returns that absolute URI as the
  result of the base-uri and document-uri functions.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.5. Please refer to the Recommended Updates
