tmt.spry.XMLDataSet

tmt.spry.XMLDataSet is JavaScript library that extends Spry's Spry.Data.XMLDataSet. The only, indeed relevant, difference is that tmt.spry.Dataset uses browser's native XPath capabilities to extract data from XML. The main benefits are:

• No need to use Google XPath JavaScript library (xpath.js). This means the browser doesn't have to load a file weighting more than 70kb
• Speed increase. Very crude benchmarks using FireFox/Firebug show an increase between 20% and 40%. The bigger the data, the more the gain

Please be advised this is library is mainly an experiment, results may vary, I recommend to test it carefully before using it in a production environment. You could face the following issues:

• Native XPath supports isn't fully consistent across browsers. Certain XPath expressions may fail to work cross-browsers
• tmt.spry.Dataset works in Safari 3.x, but fails in any previous version, since native XPath was introduced only in version 3

In order to use this library you need tmt_spry_xmldataset.js and SpryData.js from Spry
