Help With PyParsing of output from win32pdhutil.ShowAllProcesses()

[Steve]

Hi All (especially Paul McGuire!)

Could you lend a hand in the grammar and paring of the output from the
function win32pdhutil.ShowAllProcesses()?

This is the code that I have so far (it is very clumsy at the
moment) :


import string
import win32api
import win32pdhutil
import re
import pyparsing


process_info = win32pdhutil.ShowAllProcesses()

print process_info
print

## Output from ShowAllProcesses :

##Process Name   ID Process,% Processor Time,% User Time,% Privileged
Time,Virtual Bytes Peak,Virtual Bytes
##PyScripter     	 2572     0     0     0 96370688 96370688
##vmnetdhcp      	 1184     0     0     0 13942784 13942784
##vmount2        	  780     0     0     0 40497152 38400000
##ipoint         	  260     0     0     0 63074304 58531840


sProcess_Info = str(process_info)
print('type = ', type(sProcess_Info))

## Try some test data :
test = ('Process Name   ID Process,% Processor Time,% User Time,%
Privileged Time,Virtual Bytes Peak,Virtual Bytes',
        'PyScripter     	 2572     0     0     0 96370688 96370688',
        'vmnetdhcp      	 1184     0     0     0 13942784 13942784',
        'vmount2        	  780     0     0     0 40497152 38400000',
        'ipoint         	  260     0     0     0 63074304 58531840')

heading = pyparsing.Literal('Process Name   ID Process,% Processor
Time,% User Time,% Privileged Time,Virtual Bytes Peak,Virtual
Bytes').suppress()
integer = pyparsing.Word(pyparsing.nums)
process_name = pyparsing.Word(pyparsing.alphas)

#ProcessList = heading + process_name + pyparsing.OneOrMore(integer)
ProcessList = process_name + pyparsing.OneOrMore(integer)

# Now parse data and print results

for current_line in test :
    print('Current line = %s') % (current_line)

    try:
       data = ProcessList.parseString(current_line)
       print "data:", data
    except:
       pass


print('\n\nParse Actual data : \n\n')
## Parse the actual data from ShowAllProcesses :

ProcessList = heading + process_name + pyparsing.OneOrMore(integer)
data = ProcessList.parseString(sProcess_Info)
print "data:", data
print "data.asList():",
print "data keys:", data.keys()
