Was following this guide to read from xml file and write to a table.

http://www.ibm.com/developerworks/data/ ... 0703xiong/

However, columns are not getting generated after mentioning the namespace declaration as:
--------------------------------------------------------------
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
---------------------------------------------------------------
Could you please suggest where I'm I going wrong?

Thank you.

Hi,
Still in process of debugging above job. Could you please help me understand following error:

extract_CMR..XML_HDR_Tran: XML input document parsing failed. Reason: Xalan fatal error (publicId: , systemId: , line: 0, column: 0): An exception occurred! Type:NetAccessorException, Message:Could not connect to the socket for URL 'http://www.nemmco.com.au/aseXML/schemas ... ML_r22.xsd'
Xalan fatal error (publicId: , systemId: , line: 2, column: 189): Fatal error encountered during schema scan

Thank you.

Hard to say exactly...usually if the xsd cannot be found you will simply get a warning message, not an abort. At the very least, isolate it and be sure your retrieval logic works......

a) be sure you don't have "validate" checked. It will look for the xsd anyway, but it's possible that option makes it worse.
b) place the xsd local, fully qualify it, and see if you get the same symptom. I haven't seen a scenarion where the URL syntax was utilized.
c) remove the schema mention entirely, and test your logic. There is much more still to do to ensure that you are reading things correctly.

Thanks Ernie.

Issue was resolved by placing xsd locally. (Probably ds was not able to connect to online schema from unix box)

steps:
1) copy xsd to local machine (local to datastage)
2) modify path for xsd in xml files
3) import schema again from a file

Thank you.
