I have a XML file whose one of the node value changes every day once.  Now i need to script which can compare yesterdays and todays node value of the same xml file.  if they found to be same then i would assume that it is not updated.

here's what i am doing:

1. parsing the xml file to get todays node value.
2. i am keeping a downloaded copy of the same xml file from yesterday and parsing this xml file to compare todays and yesterdays node value.

Is there any better way performing this task.
