If these are not big XML files, then this is totally fine. However, if they are much larger files, it might be easier and space saving to store yesterday's value in a database engine such as MySQL and then parse the new one.<br />
<br />
If you need a sample script can I get a copy of the XML file labeled with what data you want to compare from them? I just need it for reference on which arrays to call.

hi,<br />
<br />
I have a XML file whose one of the node value changes every day once. &nbsp;Now i need to script which can compare yesterdays and todays node value of the same xml file. &nbsp;if they found to be same then i would assume that it is not updated.<br />
<br />
here's what i am doing:<br />
<br />
1. parsing the xml file to get todays node value.<br />
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.<br />
<br />
Is there any better way performing this task.<br />
<br />
Thanks

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
