Code:
sed '0,/<a class="string-array">/s//&\n<string>java<\/string>/' inputfile > outfile

This exactly worked for me.

One more hint required,

I set the pattern values into variables and trying to run. But I get below exception, can I know what wrong am doing..

Code:
sed '0,/'$searchenv'/s//&\n'$appendenv'/' config.xml > temp.xml

Error: sed '0,/'$searchenv'/s//&\n'$appendenv'/' config.xml > temp.xml

I tried double/single quote to variable in sed.

You would need to use double quotes..
Code:
searchenv='<a class="string-array">'
appendenv='<string>java<\/string>'

sed "0,/$searchenv/s//&\n$appendenv/"

Sorry just I made a mistake in setting the value to variable.

The command
Code:
 sed "0,/$searchenv/s//&\n$appendenv/" inputfile > outfile

worked perfectly.

Thanks once again.
