[omrcm]

Hi ,
I dont have use xml befor this application what I make now. Thats why I have question about xml replication. I have one xml file on local system and one file in one url( like

http://www.sitename/file/one.xml

). I'll control the xml file on the url and look if have a modification than I'll make this same modification in my local xml file. How can I make this ?

Thanks for all, and sory about my bad english...

Through HTTP, you can send a request method HEAD for the document and check the "last-modified" response header see if it is posterior with respect to your local file's last modified date.
