replacing string in xml file--revisited

[saif.shakeel]

Hi,
I need to replace a string in xml file with something else.Ex

- <SERVICEPARAMETER id="_775" Semantics="subfunction" DDORef="_54">
<SHORTNAME>rate</SHORTNAME>
<LONGNAME>rate</LONGNAME>
<VALUE role="constant" DataType="unsigned" value="1" />
<BYTEPOSITION role="position" BytePos="1" />
</SERVICEPARAMETER>
- <SERVICEPARAMETER id="_776" Semantics="localId" DDORef="_54">


Here i have opened an xml
file(small part is pasted here).I want to replace the word 'localId'
with 'dataPackageID' wherever it comes in xml file.I have asked this
before and got a code:
input_file = open(filename)
xmlcontents = input_file.read()
input_file.close()
xmlcontents = xmlcontents.replace("spam", "eggs")
output_file = open(filename,"w")
output_file.write(xmlcontents)
output_file.close()

Although this works alone it is nto
working when i handle multiple file I/O.Is there a alternative to do
this.(maybe without read() operation)
Thanks

Why do you want to change the part that *works* instead of fixing the code
that doesn't!?

try this...

#!/usr/bin/env python

from elementtree import ElementTree as et
tree = et.parse("testxml.xml")

for t in tree.getiterator("SERVICEPARAMETER"):
t.set("Semantics", "localId")

tree.write("output.xml")

After reading your post again, this might be better:

#!/usr/bin/env python

from elementtree import ElementTree as et
tree = et.parse("testxml.xml")

for t in tree.getiterator("SERVICEPARAMETER"):
if t.get("Semantics") == "localId":
t.set("Semantics", "dataPackageID")

tree.write("output.xml")

Is this code
complete,where are you replacing the localid with "datapackageid",and
where is the new xml being stored.
Thanks for the replies

You can either 1) upgrade to python 2.5 which includes the elementtree
module or 2) download and add the module to your current installation

What about trying a web search engine to answer your own question? Usually
much faster for this kind of request.
