Hi monks, I am working on converting a plain text file to html file.Now I have a scenario like below 
#Assume the file is read to $str which contains
$str="iteration 1
        some information goes here
        machine name:[some meta-info]
                 some multi-line info
        machine name:[some meta-info]
                 some multi-line info
      iteration 2
        some information goes here
        machine name:[some meta-info]
                 some multi-line info
        machine name:[some meta-info]
                 some multi-line info";
$str=~s/(iteration)(.*)/<B> uc($1)$2 <\/B>/;
print $str;

I expected the "iteration 1" and "iteration 2" to be "ITERATION 1" and "ITERATION 2", but its instead "uc(iteration 1)" and "uc(iteration 2)".
Please help me out to convert it into upper-case.Also any modules to convert plain text file to html would be helpful.TIA

ps: I know this can be done in passes by converting to uppercase in pass1 and adding tags in pass 2, but is it possible to achieve in a single substitution

The world is so big for any individual to conquer
