Problem with put URL and websites

[Fred moyer]

Until about a month ago, I have been using Revolution to find the  
drive times between two cities. I would use "put url" along with a  
line of data which included the two zip codes to get data from  
Mapquest. From all of the gibberish retrieved, my script would look  
for the words "Total Estimated Time:" and know that following that  
would be the drive time.

Suddenly, the data that is retrieved is unusable. A typical example:

div class="narrTotalTop" id="dirTimeSumm" >
Total Estimated Time: <span class="timeSpan" id="dirTimeSummary"></span>
</div>
<div class="narrTotalTop" id="dirDistSumm"  >
Total Estimated Distance: <span id="dirDistanceSummary"></span>


What has changed? Revolution? Mapquest? My Safari program? Any  
solutions? I know almost nothing about web sites.

Thanks for your help.
