When a user submits a merge request the Python script creats a subprocess and reads the stdout via a pipe (cleartool find ...) which returns elements that have a particular label. These elements appeared like; \ipsupport\ipbuild\Wizard\build.pl@@\main\buildmods\3 these elements are then checked againts previously submitted merge requests to see if there are any merge requests that require the same elements to be merged too. When the elements are read from the stdout pipe of the subprocess the backslashes aren't escaped and because these "paths" aren't real windows paths non of the os.path... path escaping methods work! Well i've solved the problem just by using pycleartool "links directly against ClearCase libraries" which returns a tuple containing (status,output,error) and the element paths in output are properly escaped. Thanks for the replies
