changingthe name of a set of files

I am trying to run the command cat on a set of files with the extension .sgm. I want the output to be in the same filename with the extention .sgml for example
That is the command:
cat *.sgm "some processing" > processedfile.sgml
How can I keep the same file name in output files. Please help.

The link you sent me shows the command used to change teh extention of a set of files. I am already using the command cat, I want the processed files using cat to be written in the same file name with a different extention so I can keep the original file and the processed file.

for i in $(ls -1 *.sgm); do cat $i | ... > $(basename $i .sgm).sgml; done
Replace "..." with the command that does your processing with STDIN and prints the result to STDOUT. This will only work if your filenames don't contain whitespace.
