The EasyXML Toolkit for LabVIEW is a simple set of VIs that make generating and parsing XML data in LabVIEW as easy as creating a cluster. It's NI Certified as Gold Compatible with LabVIEW.
Try it! You can download the free trial directly from within LabVIEW 2011. Just click on the Find LabVIEW Add-ons... link in the Getting Started window to launch the LabVIEW Tools Network. Search for EasyXML, and click the Install button. VIPM will automatically download and install EasyXML into LabVIEW, and you'll find it in your palettes immediately.
