I agree with Dave that this is not a STAF/STAX problem/question. Running a standalone Jython program or Java application that uses the same methods to get the node name of the root element's 2nd element does not work as you expected unless the config.xml file contains line breaks.
Note that you were not doing error checking in your code to get the 'ver'.
You should have checked if nodebegin.getLength() > 1 before trying to
access the 2nd node within it. For example, the following code would
print the error message instead of getting a Python error trying to call
getNodeName() on the None object:
ver = None
begin = document.getDocumentElement()
nodebegin = begin.getChildNodes()
if nodebegin.getLength() > 1:
ver = nodebegin.item(1).getNodeName()
else:
print "The root element in the xml file only has %s child so cannot
access its 2nd child" % (nodebegin.getLength())
print 'ver=%s' % (ver)
If you are simply trying to get the name of the 2nd element contained in
the xml document's root element, you could do this successfully using the
following code instead which assigns ver=unix_r12:
ver = None
nodeList = document.getElementsByTagName("operating_system")
if nodeList.getLength():
node = nodeList.item(0)
if node.getNodeType() == Node.ELEMENT_NODE:
children = node.getChildNodes()
if children.getLength() > 0:
thisChild = children.item(0)
ver = thisChild.getNodeName()
print 'ver=%s' % (ver)

Re: [staf-users] Getting attribut error "AttributeError: 'None' object has
no attribute 'getNodeName'" on parsign a xml file.
It seems to be a Java issue. If I create a standalone Java application
(see the attached parse.java file) that does the same parsing as your
parsejob.xml file, it gets a NullPointerException (unless I change the
formatting of the config.xml file):
$ java parse
machine_name=etr6506l3-sun66.ca.com
prerequisitescript=update.exp
acbuildpath=/CR_80SP1/80_builds/Unix/CR16/TestFix
testsuitscript=runQuickSanity.sh
reportname=BATReport
testdir=/testQuickSanity
testconfig=BlueExpress.tar
java.lang.NullPointerException
at parse.main(parse.java:198)
Line 198 in the parse.java file is:
String ver = nodebegin.item(1).getNodeName();
which is the equivalent line (560) in your parsejob.xml file that gets the
error:
ver = nodebegin.item(1).getNodeName()
AttributeError: 'None' object has no attribute 'getNodeName'
So it seems that unless you change the formatting of the config.xml file,
nodebegin.item(1) is null.
(See attached file: parse.java)

Re: [staf-users] Getting attribut error "AttributeError: 'None' object has

Hi David ,
I am generating the xml file through dom in javascript. The same xml file
i can read through javascript dom methods , i am able to read the xml even
if it is not formatted as you say. I am attaching here the code for that .
Try this asp file try to read the xml from "c:/config.xml". But the same
xml file i am not able to read from staf job.
But surprisingly if i open it in a editor , do nothing and simply save the
file , it gets read from staf job.
I am not sure if this is some xml encoding problem. I was able to read
similar xml file before from staf.
Regards
Sangram

And when I run your parsejob.xml job with the config.xml file, I get the
same error. If I format the config.xml file as:

</tests>
<machine_name>etr6506l3-sun66.ca.com</machine_name>
</unix_r12>
</operating_system>
Then the error no longer occurs when running parsejob.xml.

[staf-users] Getting attribut error "AttributeError: 'None' object has no

Hi ,
I am encountering the following error :
"AttributeError: 'None' object has no attribute 'getNodeName'" on parsing
a xml file."
This a new problem i am getting , never earlier got this problem .
The xml file to be parsed is :
=====================
<?xml version="1.0" encoding="utf-8"?>
<operating_system>
<unix_r12>
<tests type="quickSanityTest">
<prerequisitescript>update.exp</prerequisitescript>
<acbuildpath>/CR_80SP1/80_builds/Unix/CR16/TestFix</acbuildpath>
<testsuitscript>runQuickSanity.sh</testsuitscript>
<testdir>/testQuickSanity</testdir>
<testconfig>BlueExpress.tar</testconfig>
<reportname>BATReport</reportname>
</tests>
<machine_name>etr6506l3-sun66.ca.com</machine_name>
</unix_r12>
</operating_system>
Attached is the exact file that i am using to parse:
The staf job file "parsejob.xml is also attached here:
I get the error :
20100315-15:09:48 STAXPythonEvaluationError signal raised. Terminating
job.
===== XML Information =====
File: C:\STAF\stax_jobs\parsejob.xml, Machine: baksa03-xp.ca.com
Line 403: Error in element type "script".
===== Python Error Information =====

sequence: 2/4 (Line: 391, File: C:\STAF\stax_jobs\parsejob.xml, Machine:
baksa03-xp.ca.com)
]
I have validated the xml file to be valid by MSXML valid . It is valid .
Now the same xml file gets read if i Ctrl-x the following in the xml file
:
<tests type="quickSanityTest">
<prerequisitescript>update.exp</prerequisitescript>
<acbuildpath>/CR_80SP1/80_builds/Unix/CR16/TestFix</acbuildpath>
<testsuitscript>runQuickSanity.sh</testsuitscript>
<testdir>/testQuickSanity</testdir>
<testconfig>BlueExpress.tar</testconfig>
<reportname>BATReport</reportname>
and paste it again at the same location in the xml file. The xml file then
gets parsed through the staf job as i have attched.
Please suggest , i am not understanding this problem .

Sangram
