Could you specifiy the output are you looking for? What have you tried so far?

Other than the double trailing space laknar expects after the 1st and 3rd occurrences of </RequestType> and the single trailing space laknar expects after the 2nd occurence of </RequestType>, the following seems to produce the expected output:
Code:
awk -F: '/<CardinalMPI>/{
        printf("<CardinalMPI>\n<StartDate>%s</StartDate>\n", previous)
        printf("<RequestType>%s:%s:</RequestType>\n", $1, $2)
        previous = ""
        next}
{       if(previous != "") printf("%s\n", previous)
        previous = $0}
END {   if(previous != "") printf("%s\n", previous)}' input
