Its a great plugin that you have to copy paste in the "MyDocument\Visual Studio(2005/2008)\Visualizers" directory.
I really wanted a tool where I can just load the Xml into memory and play with the XPath Queries.This visualizer lets me do that and more.

1) I can easily add a XPath Query and check the results.

As you can see in this screenshot I have added a XPathQuery and you can see the results in the output. Very nice feature while debugging.... or if you are doing some xml parsing.
2) I can see the xml output in a browser.
3) I can create StyleSheets and use them to style my Xml file contents.
You can download the XmlVisualizer 2.0 from CodePlex.

I think developers can be definitely more productive if they use this tool.
Happy Programming!!!
