HI,
         Thanks for the reply.that seems to work,but i was doing this
so as to attach it to a bigger code where it will be utilised before a
parsing.

#Input file and Output file path from user

file_input = raw_input("Enter The ODX File Path:")

(shortname,ext)=os.path.splitext(file_input)
f_open_out=shortname+".ini"
log=shortname+".xls"
test_file=shortname+"testxml.xml"

saveout = sys.stdout

input_xml = open(file_input,'r')
xmlcont=input_xml.read()
xmlcont=xmlcont.replace('localId','dataPackageId')
output_file = open(test_file,"w")
output_file.write(xmlcont)
output_file.close()

f_open=open(f_open_out, 'w')
logfile=open(log,"w")

sys.stdout = f_open

#Parse the input file,and check for correct ODX  version

xmldoc = minidom.parse(input_xml)


                    I am opening 2 more files in addition to the file
where the new xml goes.One file is written using the sys.stdout
command as most of the output has to go there printing takes place in
many places (so cant use f_open.write) each time.
                    When i attach the part of replacing the string
'localid' in xml file with something else as given above with
xmlcont=xmlcont.replace('localId','dataPackageId')
the code does not run and hangs.Can more than 3 files be opened at a
time .I dotn know what the problem is here.
                     Thanks
