Hi guys...

I wrote an external python script which would grab some HTML and so some text 
and file preprocessing.

The script then is supposed to run come command line methods... using 
os.system() .. however when i run the script triggered by my DTML code it 
manages to do the grabbing of the html and saving it into a file ans stuff... 
but once it hits the portion where its supposed to run the command lines.. it 
just skips everything and goes right to the end.... after which this error 
message is shown :

 Error Type
    IOError
Error Value
    [Errno 2] No such file or directory: 
'/var/lib/zope2.8/instance/plone-site/Extensions/output.txt'
Request made at

If the command line executables had run this error would not occur as one of 
the jar files was supposed to output a text file called output.txt.

I tried running this script, modified on its own off the terminal using "python 
test.py" and it works perfectly... but once DTML calls this script it is unable 
to run the cammand line portion...

can anyone please help me out or point me in the right direction... 

Thanks and regards

wan


Here is my code :

        tgtString = re.sub('<([^>]([^>]|\n)*)>', '', tgtString)
        tgtString = re.sub('\n', '', tgtString)
        tgtString = re.sub('\t', '', tgtString)
        tgtString = re.sub('\r', '', tgtString)
        tgtString = re.sub('  ', '', tgtString)
