file Error

[saif.shakeel at gmail.com]

Hi,
    I am parsing an xml file,and using raw_input command to ask the
user to enter the file name.Ex

>>>
Enter The ODX File Path:

Suppose my code does not work properly,then in the python idle window
it shows something like this:
>>>
C:\Projects\ODX Import\Sample Files\MiscFiles
\CIM_A3300_diag_spec_sw49.xml
Traceback (most recent call last):
  File "C:\Projects\ODX Import\code_ini\odxparse_mod_off_comm.py",
line 339, in <module>
    process_variant(variant)
  File "C:\Projects\ODX Import\code_ini\odxparse_mod_off_comm.py",
line 285, in process_variant
    triplet = triplet + get_did_lengths(iservice,local_service_id)
  File "C:\Projects\ODX Import\code_ini\odxparse_mod_off_comm.py",
line 238, in get_did_lengths
    local_min = local_min + ddoref_min[ddorefstring]
KeyError: '_210'

           This is some bug related to code ..thats ok..but when i run
the program immediately again for some other input..then it does not
show the prompt :
>>>
Enter The ODX File Path:

               but instead a blinking prompt which accepts the
filename something like this:
>>>
C:\Projects\ODX Import\Sample Files\MiscFiles\Diagnostic CTS Global
Epsilon TIM V1.4.xml

                I want the inputfile prompt to appear regardless of
the error condition.I dont know where the problem lies.Can someone
help me out.
                     Thanks
