Adam Crume commented on JXPATH-86:
----------------------------------
My issue is not with the way the document is structured, although I was
misunderstanding it. My main issue is that, no matter what "/array" resolves
to, "/array/." should resolve to exactly the same thing. Considering what you
quoted from the docs:
For example, if property "foo" of the context node has a Container as its
value, the XPath "foo" will produce the contents of that Container, not the
container itself.
doesn't that imply that "/array" should return the contents of the array (or
the first element with getPath()) instead of the array itself?
This is still an issue in SVN HEAD.

> Key: JXPATH-86
> URL: https://issues.apache.org/jira/browse/JXPATH-86
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.2 Final
> Reporter: Adam Crume
>
> The . selector should always return the context node, and the * selector
> should return child elements. However, this doesn't work for arrays:
> JXPathContext context = JXPathContext.newContext(new HashMap());
> context.setValue("array", new String[] {"one", "two", "three"});
> context.setValue("array2", new String[][] { {"a", "b"}, {"c", "d"}});
> context.setValue("person", new Person("Bob", 25));
> String[] paths = {"/array", "/array/.", "/array/*", "/person", "/person/.",
> "/person/*"};
> for(int i = 0; i < paths.length; i++) {
> Pointer pointer = context.getPointer(paths[i]);
> System.out.println(pointer.asPath());
> Object value = context.getValue(paths[i]);
> System.out.println(value);
> System.out.println();
> }
> This produces the following output:
> /[EMAIL PROTECTED]'array']
> [Ljava.lang.String;@59b659b6
> /[EMAIL PROTECTED]'array'][1]
> one
> /[EMAIL PROTECTED]'array'][1]/bytes[1]
> 111
> /[EMAIL PROTECTED]'person']
> [EMAIL PROTECTED]
> /[EMAIL PROTECTED]'person']
> [EMAIL PROTECTED]
> /[EMAIL PROTECTED]'person']/age
> 25
