parse .txt file

I have a .txt file that logs data every 1 min for certain elements and would like to parse the text file to show only every 5mins to the user. I have attached the txt file and the VI I'm working on with this question.

 

 

For example the text file shows for ECG Rate: ECGRATE$<UNIT=/min>&<TIME=2014-01-28T09:37:18><VALUE=44>&<TIME=2014-01-28T09:38:19><VALUE=44>&<TIME=2014-01-28T09:39:18><VALUE=47>&<TIME=2014-01-28T09:40:18><VALUE=45>&<TIME=2014-01-28T09:41:19><VALUE=43>&<TIME=2014-01-28T09:42:18><VALUE=42>&<TIME=2014-01-28T09:43:19><VALUE=44>&<TIME=2014-01-28T09:44:18><VALUE=46>&<TIME=2014-01-28T09:45:18>

 

I would like to display the current value on the front panel only every five mins. 

Bonus would be in addition to the above would be plot all values on a graph also, but lets start with the first step.

I found this community example on how to parse a text file line by line. Perhaps you could modify it to suit your needs:
