Actually you can replace those as well (but then the first delimiter needs to be escaped with a backslash):
Code:
$ PMTargetFilePath=/foo/bar
$ echo '<ATTRIBUTE NAME ="Output file directory" VALUE ="/abc/khi/"/>' | sed '\|Output|s|VALUE =[^>]*>'"|value = $PMTargetFilePath|"
<ATTRIBUTE NAME ="Output file directory" value = foo/bar

Thanks Reviewers, I reached quite close to what I am looking for by working on your suggestion
Code:
 
sed '/Output/s|VALUE =[^>]*>'"|value = \"\$PMRootDir\\\data\\\output\\\\\"/>|g" <sampledataoncemore> result2

.
Additionally I also need to remove the file path prefixed to a file name example
Code:
<ATTRIBUTE NAME ="Output filename" VALUE ="/abc\khi/amv.txt/"/>

and
Code:
<ATTRIBUTE NAME ="Output file name" VALUE ="/abc\khi/amv.csv/"/>

should be
Code:
<ATTRIBUTE NAME ="Output filename" VALUE ="amv.txt/"/>

and
Code:
<ATTRIBUTE NAME ="Output file name" VALUE ="amv.csv/"/>

. I tried
Code:
sed '/"Output file name"/ s basename <samplefinaldata> result2

, but this is unterminated command. As i am very new to Unix , Kindly suggest what am I missing here .

There's an opening single quote right after sed, but the closing one somewhere before result2 is missing... and, while it seems possible to use spaces as delimiters for s(ubstitute) commands, it is quite misleading and error prone.

Got your point and tried to correct the mistake by
Code:
sed '/"Output file name"/s basename <samplefinaldata>' result2

but it gives an error sed: command garbled. My requirement is to remove the filepath from number of filenames encountered in a file.
please help.
thanks Again.

Tried this one also
Code:
sed '/."Output file name"/s/basename<samplefinaldata>'result2

...but not getting the desired output.

Code:
PMTargetFilePath=amv.txt/
sed '/ATTRIBUTE NAME *= *"Output file directory/ s|\(VALUE *= *\)"[^"]*"|\1"'"$PMTargetFilePath"'"|' result2

--
Your can assemble your (changing?) requirements in one multi-line sed statement:
Code:
sed '
/ATTRIBUTE NAME *= *"Output file directory"/ s|\(VALUE *= *\)"[^"]*"|\1"'"$PMRootDir"'"|
/ATTRIBUTE NAME *= *"Output file name"/ s|\(VALUE *= *\)"[^"]*"|\1"'"$PMTargetFilePath"'"|
' result2

thanks for looking into this, I managed to change the file directory additionaly I need to strip off the directory from filename as mentioned in post 9. I tried few commands like
Code:
grep "Output filename" inputfilename |xargs basename

, but this throws an error
Usage: basename string [ suffix ]
it would be great if you can help me on this. a sample line of my input file looks like
<ATTRIBUTE NAME ="Output filename " VALUE ="/could/be/anything/filename"/
<ATTRIBUTE NAME ="Output filename " VALUE ="/could/be\something.txt"/>
and I need
<ATTRIBUTE NAME ="Output filename " VALUE ="filename"/
<ATTRIBUTE NAME ="Output filename " VALUE ="something.txt"/>

Just strip the characters up to the last / or \ within the " " after VALUE=:
Code:
sed '
/ATTRIBUTE NAME *= *" *Output file name *"/ s|\(VALUE *= *"\)[^"]*[/\]|\1|
/ATTRIBUTE NAME *= *" *Output filename *"/ s|\(VALUE *= *"\)[^"]*[/\]|\1|
' result2
