AquaPath is a Developer Tool that allows you to evaluate XPath 2.0 expressions against any XML document and view the result sequence in a dynamic, intuitive tree representation.
Using AquaPath is simple. Paste the contents of an existing XML document or even author an XML document using AquaPath itself (AquaPath is also a rudimentary text editor). The source text of your XML document appears under the "Source" tab in an AquaPath document window. Use this tab to author or edit your document.
Next, type an XPath expression into the "XPath" text field at the top of the AquaPath document window. Click "Evaluate" to see the matching node sequence. You will see a status bar message just below the XPath text field showing either the number of nodes in the result sequence or and error message if your XML document is not well-formed or if your XPath expression is invalid.
Under the "String-Value" tab, you'll find a text area containing the string value of the result sequence.
