Liquid XML - The good juice
I haven't used Liquid XML in some time and had forgotten how good value this little tool is. XML editing, instance document generation, schema validation and more, XPath query tool, all for free. The schema document visualisation is really strong too.
Awesome tool, and hats off to Liquid Technologies for making such an awesome tool available free to use. Thanks.
Go check it out at http://www.liquid-technologies.com/ and have a look at the rest of their tools while you are there,
