How to access `@attribute` in a TOPs python processor?

[eldrich]

Hey folks,
I'm executing a Windows .bat file which is written out by a pythonprocessor TOPs node to run some things on another sever.
Everything works if I hardcode the filename to the batch file, but I want it to generate and execute .bat files for each work item

I'm trying to access `@filename`in the pythonprocessor, but not getting anywhere. 
How can I access the attribute so .format fills in the path correctly?

PidginCode:

outFile = `@filename`
filePath = "path to directory/{}".format(outFile)

The sample file docs are bereft of examples so I'm wondering if I'm going about it the wrong way.
Thoughts? 
 

EDIT: I made a string parameter on the node I'm querying and pointed evalParm at it.
Is that the most sensible way? 

 

node = hou.node('/obj/topnet1/nodeName')

parmName = str(node.evalParm('parm'))

If you are doing per work item, I think it's better to use python script node instead of python processor.

It will go through all work items one by one

outFile = work_item.attribValue('filename')

If you are using python processor, It only run once, so you have to use a loop to go through all the items and get the values one by one

outFile1 = upstream_items[0].attribValue("filename")
