Try something like the following:
sed -e 's/\(\w*\)\(\s*->\s*comm\)/((PetscObject)\1)\2/g'
here \w* should match any number of alfanumerics + underscores
\s* matches any number of blanks
in the second part of s/part1/part2/,
the \1 substitutes the bit in part1 between the first pair of \( .. \)
and \2 substitutes the second pair.
Always be careful using this type of automated replacements as
unexpected behaviour is always to be expected! You might want to xxdiff
the results for instance.
