There is a problem with the minidom package provided with Jython 2.1 (which is what STAX currently uses). Instead, you may want use a Java DOM Parser to parse an XML file via Jython code within a <script> element in a STAX job. Note that Jython allows you to import and use Java classes (as Jython is the Java implementation of Python) in addition to using Python modules. See section "2.6.7 How can I parse an XML file from a STAX job?" in the STAF/STAX FAQ at http://staf.sourceforge.net/current/STAFFAQ.htm#d0e736 for an example of how to parse an XML file using a Java DOM parser within a <script> element in a STAX job.
Note that if you google for the minidom "AttributeError: feed" error message and Jython 2.1, you'll see that many hits about a problem with the minidom package provided with Jython 2.1. Or, you can search the STAF forums / mailing lists on SourceForge (there's a link to search in the navigation column on the left on the STAF SourceForge home page at http://staf.sourceforge.net) and you'll see that this question has already been asked and answered via: http://sourceforge.net/projects/staf/forums/forum/104046/topic/1727421?message=4292971 -------------------------------------------------------------- Sharon Lucas IBM Austin, luc...@us.ibm.com (512) 286-7313 or Tieline 363-7313 staf-stax user <stafstaxu...@gmail.com> 01/05/2010 11:34 AM To David Bender/Austin/i...@ibmus cc staf-users@lists.sourceforge.net Subject Re: [staf-users] Issues while importing external python modules.

It seems that lxml is built for specific versions of Python (and does not appear to support Python 2.1), so I don't think you will be able to use lxml within your STAX job. Using "import xml.etree.cElementTree as etree" within the <script> results in "ImportError: No module named etree".
