XOM API for Processing XML with Java

Hello,

I read 'XOM XPath Mapping' at the XOM site, and have some
questions on empty text nodes. I tried the following test
case, in which a empty text node was followed by one text node.
I had the expected result with success.

    public void testAdjacentTextNodes() {
        Element parent = new Element("parent");
        Text empty = new Text("");
        Text nonempty = new Text("value");
        parent.appendChild(empty);
        parent.appendChild(nonempty);
        Nodes result = parent.query("node()");
        assertEquals(2, result.size());
        
        Nodes result2 = parent.query("/*[count(node())=1]");
        assertEquals(1, result2.size());
        assertEquals(parent, result2.get(0));
        
        Nodes nodes1 = parent.query("node()[1]");
        assertEquals(2, nodes1.size());
        Nodes nodes2 = parent.query("node()[2]");
        assertEquals(0, nodes2.size());
    }


So I tried two examples, in which a empty text node follows
one nonempty text node, and a empty text node was followed
by two nonempty text nodes.
I had expected commented statements, which failed.
The following test cases went with success instead.


    public void testAdjacentTextNodes2() {
        Element parent = new Element("parent");
        Text empty = new Text("");
        Text nonempty = new Text("value");
        parent.appendChild(nonempty);
        parent.appendChild(empty);
        // Expected the following:
        // Nodes result = parent.query("node()");
        // assertEquals(2, result.size());
        try {
            Nodes result = parent.query("node()");
            fail();
        } catch (XPathException notExpected) {
            assertTrue(true);
        }
        // Expected the following:
        // Nodes result2 = parent.query("/*[count(node())=1]");
        Nodes result2 = parent.query("/*[count(node())=2]");
        assertEquals(1, result2.size());
        assertEquals(parent, result2.get(0));
        
        Nodes nodes1 = parent.query("node()[1]");
        assertEquals(2, nodes1.size());
        // Expected the following:
        // Nodes nodes2 = parent.query("node()[2]");
        // assertEquals(0, nodes2.size());
        try {
            Nodes nodes2 = parent.query("node()[2]");
            fail();
        } catch (XPathException notExpected) {
            assertTrue(true);
        }
    }

    public void testAdjacentTextNodes3() {
        Element parent = new Element("parent");
        Text empty = new Text("");
        Text nonempty = new Text("value");
        Text nonempty2 = new Text("value2");
        parent.appendChild(empty);
        parent.appendChild(nonempty);
        parent.appendChild(nonempty2);
        // Expected the following:
        //Nodes result = parent.query("node()");
        //assertEquals(3, result.size());
        try {
            Nodes result = parent.query("node()");
            fail();
        } catch (XPathException notExpected) {
            assertTrue(true);
        }
        // Expected the following:
        // Nodes result2 = parent.query("/*[count(node())=1]");
        Nodes result2 = parent.query("/*[count(node())=2]");
        assertEquals(1, result2.size());
        assertEquals(parent, result2.get(0));
        
        Nodes nodes1 = parent.query("node()[1]");
        assertEquals(3, nodes1.size());
        // Expected the following:
        // Nodes nodes2 = parent.query("node()[2]");
        // assertEquals(0, nodes2.size());
        try {
            Nodes nodes2 = parent.query("node()[2]");
            fail();
        } catch (XPathException notExpected) {
            assertTrue(true);
        }
    }


I think that these may be bugs, or I am confused.
Could you give me any suggestion?
I use XOM 1.1 d3.

Thanks,
