in which SVG viewer/implementation? ASV and Batik, e.g. don't support XMLHttpRequest. They support getURL(). In order to support all of the viewers you must fork your code and see which method is available. You can write a helper object or function for this. http://www.carto.net/papers/svg/resources/helper_functions.js e.g. has a getXMLData object that you could use for that purpose. In order to use it, you can write the following code: var myGetXMLObj = new getXMLData(url,callBackFunction); myGetXMLObj.getData(); You get back a ready to use XML node that you can either append to the DOM (if SVG compatible) or parse per script. I don't know how well it works with thousands of elements. Many of the current SVG viewers might not be fast enough to process huge amounts of data.
