You can have multiple lines of Python code within a <script> element, as
long as it is all valid Python code. You just keep introducing errors in
your Python code. :-)
Note that in the following error message, the error message pointing to a
syntax error in line 3, column 27 of your <script> element:
Python code compile failed for:
[machine_name] =STAXResult
print machine_name
Traceback(innermost last):
(no code object at line 0)
SyntaxError : ('invalidsyntax',('<string>',3,27,' print \t\t\t length =
len(machine_name')))
The error message shows that you have a unmatched single quote after
machine_name.
<script>
[machine_name] = STAXResult
print machine_name
length = len(machine_name') # Note the single quote that is causing
the error
</script>

Re: [staf-users] Error in using jython funtion len()
Hi Sharon,
Basically i get syntax error on trying to write any python code in
it is a syntax error problem...
<script>
[machine_name] = STAXResult
length = len(machine_name)
</script>
Python code compile failed for:
[machine_name] =STAXResult
print machine_name
Traceback(innermost last):
(no code object at line 0)
SyntaxError : ('invalidsyntax',('<string>',3,27,' print \t\t\t length =
len(machine_name')))
Do we have to import anything inside the script tags to make the code work
??
Regards

Hi Sharon,
Thanks for your quick reply.
I am rather new to xml parsing ,so your help will be highly appreciated
and would be a time saver.
My intent is to parse the xml file get values from it and :
===========================================
The XML file is :
<?xml version="1.0" encoding="utf-8" ?>
- <operating_system>
- <unix_80sp1>
- <tests type="quick_sanity_test">
<prerequisitescript>preparequicksanityscript</prerequisitescript>
<acbuildpath>acbuildpath</acbuildpath>
<testsuitscript>test quick sanity script</testsuitscript>
<testdir>quick sanity dir</testdir>
</tests>
<machine_name>u80sp1_L004</machine_name>
<machine_name>u80sp1_L005</machine_name>
<machine_name>xyz.pxy.dxe.cde</machine_name>
<vmware id="155.35.3.55">144.35.3.90</vmware>
<vmware id="155.35.3.56">144.35.3.91</vmware>
</unix_80sp1>
</operating_system>
I want to parse the above file and collect
1. All the machine_name in a list variable in a variable say mac_name
2. All the vmware tag attributes in a list variable say vmware_attr and
corresponding values in another list variable say vmware_value
I am parsing the above in the function "parseXML" as mentioned below.
In doing so i was getting the following problems.
1. I was not able to get all the mach names in the list variable mac_name
, i only got the last one xyz.pxy.dxe.cde
when i want all the three u80sp1_L004 u80sp1_L004 and xyz.pxy.dxe.cde.
But when i changed the xml file a little bit i could get all the values .
I had only one machine_name tag this way
<machine_name> u80sp1_L004,u80sp1_L004,xyz.pxy.dxe.cde<\machine_name>. It
worked this way.
My question how : could i still parse it with three tags with same name.
2. When i collect the three machine names and return it and try to get the
length i get error. (length = len(mach_name))
3. I am not sure how to get the vmware tag attributes and vmware tag
values.
The code i am using is :
I think the code need to be modified a little bit to get the values
properly/ or even maybe the xml format to be modified to parse properly.

Sangram,
I need more information as you didn't provide the contents of function
"parseXML". Perhaps it isn't returning what you think it is. You should
add more debugging to log the value of variable machine_name and its type.
Note that if the len() function works on PyStrings and PyList, so that's
why it is important to understand what type of variable machine_name is,
as well as what its value is. Also, what is the complete error
information that you are getting. Note that it would be helpful to
provide the complete STAX job so that we could run it to recreate the
problem (e.g. you didn't provide function "parseXML" so I don't know what
exactly it is returning).
Change your STAX xml function to the following so that you can see what
variable machine_name's value and type is and provide the log output and
error information.
<stax>
<defaultcall function="Main"/>
<function name="Main">
<sequence>
<!-- Assign the file name of a STAX xml document you want to parse
-->
<call function="'parseXML'">'c:/MyXml.xml'</call>
<script>
[name, machine_name] = STAXResult
</script>
<log message="1">'type(machine_name)=%s' %
(type(machine_name))</log>
<log message="1">'machine_name=%s' % (machine_name)</log>
<script>length = len(machine_name)</script>
<log message="1">'len(machine_name)=%s' % (length)</log>
<log message="1">'Name: %s' % (name)</log>
<log message="1">'Machine_name: %s' % (machine_name)</log>
</sequence>
</function>
</stax>

[staf-users] Error in using jython funtion len()
Hi ,
In the following stax job i am trying to read the length of a list
machine_name.
But i get syntax error while trying to do so . The code is highlighted in
yellow.
<stax>
<defaultcall function="Main"/>
<function name="Main">
<sequence>
<!-- Assign the file name of a STAX xml document you want to parse
-->
<call function="'parseXML'">'c:/MyXml.xml'</call>
<script>
[name, machine_name] = STAXResult
length = len(machine_name) ========> i am getting syntax error
here ...is this a wrong way to do in this section?
</script>
<log message="1">'Name: %s' % (name)</log>
<log message="1">'Machine_name: %s' % (machine_name)</log>
</sequence>
</function>
</stax>
