regex - Write a regular expression to parse following string -

i using sed command , want parse following string:

mr. xyz                              mr. abc, pqr ward-2, abc                   vs.    mg road, pune,                                      pune dist.,  (appellant)                          (respondent) 

now want parse above string , want appellant part separated above example , respondent part separated.

that want following output:

mr. xyz ward-2, abc(appellant) 1 output , mr. abc, pqr mg road, pune, pune dist.,(respondent) output using sed command.

i used following regex not getting proper output:

sed -n '/assessment year/i{ :loop; n; /respondent/iq; p; b loop}' abc.txt 

sed wrong tool job involves looking @ multiple lines. use awk, it's invented for. here's gnu awk couple of extensions:

$ cat tst.awk begin { fieldwidths="30 7 99" } {     (i=1;i<=nf;i++) {         gsub(/^\s*|\s*$/,"",$i)         if ($i != "") {             rec[i] = (rec[i]=="" ? "" : rec[i] " ") $i         }     } } /^\(/ {     print rec[1]     print rec[3]     delete rec } $ $ awk -f tst.awk file mr. xyz ward-2, abc (appellant) mr. abc, pqr mg road, pune, pune dist., (respondent)
