Note that the following is code that you had working many months ago and
still runs fine for me. Note that after running:
[name, machine_name] = STAXResult
the value assigned to machine_name is a PyString containing some IP
addresses (or hostnames) separated by commas.
You then are creating a PyList named machineList from this PyString using
the string function's split method (specifying a comma as the string
separator) so that it contains a list of these IP addresses (or
hostnames).
machineList = machine_name.split(',')
Here's the code that you had working many months ago and still runs fine
for me.

Re: [staf-users] Error in using jython funtion len()
Hi Sharon,
If you have any updates about my observation, do let know.
Actually i have to write some jython logic in a script block , which may
be multi lined .
I am not sure why this syntax error behaviour. Do u observe the same on
your side.

Hi Sharon,
If i use your suggestion as :
<script>length = len(machine_name)</script>
<script>machList = machine_name.split(',')</script>
I do not get any syntax error .It works fine.
But if i do a
<script>
[machine_name,vmware_name] = STAXResult
machList = machine_name.split(',')
</script >
I get syntax errors.
So are we not supossed to use multiple statements within a <script>
</script>??

Hi Sharon,
Also i tried what you had suggested :
<script>
[machine_name,vmware_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">'Machine_name: %s' % (machine_name)</log>
I get the ouput as :
type(machine_name) = org.python.core.PyString
machine_name = u80sp1_L004, u80sp1_L005, u80sp1_L006
len(machine_name) = 37
Machine_name: u80sp1_L004, u80sp1_L005, u80sp1_L006

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>

Sangram
