I have to edit a lot of XSLT files for my current project. Most files are XSLT 2.0 stylesheets and the previous versions of NetBeans didn't have code completion while editing the files. But NetBeans 6.5 has code completion for XSL 2.0 stylesheets! This really is a time saver for me. To enable code completion we must install the XSLT plugin. We go to Tools | Plugins | Available plugins and look for the XSLT plugin in the SOA category. After the plugin is installed we have code completion in the editor.
