Finding Last occurance of a word to gather key information

Question

I am wondering how to find the last occurance of a word using coldfusion to gather the data i need. I am using some of the google maps XML code and the last occurance of distance gives the total distance which is what i need. How would I be able to find the last occurance and take the data from the code and place it in a template?

Here is the code, the last <distance> tag contains the total distance of the trip which is the only thing I am interested in.
