From the developer:
Visual XML is a simple, free XML visualization tool for XML API server/client developers. Using this Visual XML tool, users will be able to access remote or local address to XML server and refresh its results with a click. Or just paste raw XML document.
You also can test POST method using simple http query expressions.
