I really need it asap. Hope someone can help me. Thanks!

If you have the whole XML on ONE line (a very simplified non bullet-proof approach) :
nawk -f ay.awk ay.xml
ay.awk:
Code:
BEGIN {
   FS="[><]"
}
{
  for(i=8; i<=NF; i+=2) {
          if ( $i ~ /^[/]/ ) continue
          printf("name->[%s] value->[%s]\n", $i, $(i+1))
  }
}

If you have your XML in a different format, pls post the sample using vB-code tags.

       -O, --original-string=value
	      XML is contained in the supplied string
