Ok. To answer the second part first. To strip out carriage returns from your input file do:
awk '{printf("%s"), $0}' filename > newfile
The awk command should be standard across most Unix O/S.
In HP-UX use the functions: regcomp, regexec. These functions allow you to process regular expressions. In other words you may search a string for a pattern (like the ones you have described).
Sorry I don't have time to explain these functions in depth or write you a little test program, but regexec will point you to where it finds the first match in your line (in a pointer). If you called the function again it will return a pointer to the next pattern in your string. To work out the number of characters between each expression found you would subtract the first pointer value from the second pointer value and so on ...
I do know that you may have portability issues with the regexec and regcomp functions. When my trainee wrote a program and ported it to windows he found that a different library with different function names was required. To make matters worse the windows functions had different rules for regular expressions.
I would not be surprised if you encountered similiar issues between different flavours of Unix.
If portability is an issue you may have to write your own parsing algorithms ...
Sorry I can't be more help but I have run out of time ...
