Hi, We have an application which reads 1000’s of locations from the xml file and will display all those locations in the google map. We have implemented the following approach for this… 1. Read all the data from xml files at the time of page load and pass it to the client side. 2. this data will be used for all the furthur operations on the google map. The above approach is working fine if there are less no of locations. But if there are more lcations, it is taking huge amount of time to parse the data from xml files. Is there any better approach to do it. Please help me. Thanks in Advance ---

Please help me. First of all, profile your code. If the bottleneck is the xml parser, then what xml parser are you using? If you haven’t already, XMLParser ([http://www.yoshidam.net/Ruby.html](http://www.yoshidam.net/Ruby.html)) might be worth a look. It’s some ruby interfaces to expat so should be pretty speedy. Fred
