[jdom-interest] does XPath implementation work correctly?

[Robert Koberg]

It does not return what I would expect after using XPath in writing many
XSLT stylesheets.
Here are some XPath examples (xml is at the bottom of the post):
----------------------------------------------------------------------------
---------------------
Given an XPath expression of:
XPath xpath = new XPath("/");
returns...
[[Document: [DocType: <!DOCTYPE section>] Root - [Element: <section/>]]]
-- I would expect the entire document represented somehow
------------------------------------
given:
XPath xpath = new XPath("/@id");
returns...
[[Attribute: id="root"]]
-- I would expect this to return just 'root', but actually I would expect
the next expression to return the 'root' attribute value
-- there should be no value for this expression
-------------------------------------
given:
XPath xpath = new XPath("/section/@id");
returns...
[[Attribute: id="docs_000000001"], [Attribute: id="floaters_000000001"]]
-- I would expect this to return 'root'
-- it is returning the second level section 'id' attributes. In XSLT/XPath I
would have to write:
select="/section/section/@id"
-------------------------------------
given:
XPath xpath = new XPath("//*[@id='docs_000000001']");
returns...
[[Element: <section/>]]
-- I would expect this to return a representation of the child nodes of the
first child section
-------------------------------------
given:
XPath xpath = new XPath("//*[@id='docs_000000001']/@folder-name");
returns...
[[Attribute: folder-name="docs"]]
-- This seems correct but why doesn't it just return 'docs'?

The XML I ran the tests against:
