XOM API for Processing XML with Java

[Regier Avery J <RegierAveryJ AT JohnDeere.com>]

This release resulted in a surprising failure for me.  I've been successfully 
giving a prefix to the default namespace of a document using:

XPathContext context = 
XPathContext.makeNamespaceContext(doc.getRootElement());
context.addNamespace("a", context.lookup(""));

This now fails because the lookup results in a null.  Here's the test case.

package com.deere.axiom.rest.followpass;

import static org.junit.Assert.assertEquals;

import java.io.IOException;
import java.io.StringReader;

import nu.xom.Builder;
import nu.xom.Document;
import nu.xom.Nodes;
import nu.xom.ParsingException;
import nu.xom.ValidityException;
import nu.xom.XPathContext;

import org.junit.Test;


public class ERHTest {
        
        // This test fails with 
        // nu.xom.XPathException: XPath error: Cannot resolve namespace 
prefix 'a'
        @Test
        public void testNotWithNamespaceGenericLookup() throws 
ValidityException, ParsingException, IOException {
                Document doc = new Builder().build(new StringReader("<hi 
xmlns='there://mr.space/alien'/>"));
                XPathContext context = 
XPathContext.makeNamespaceContext(doc.getRootElement());
                context.addNamespace("a", context.lookup(""));
                Nodes query = doc.query("//*[not(self::a:human)]", context);
                assertEquals(1, query.size());
        }

}

Subject: [XOM-interest] XOM 1.2.8 released

I've posted XOM 1.2.8 in the usual location:

http://www.xom.nu/

This release fixes several bugs in XPath processing that have shown up
in the last month or two, including a nasty incompatibility with Java
7 that could throw an IllegalArgumentException when evaluating
expression that select attributes with a union operator. If you use
XPath at all, I recommend you upgrade at your earliest convenience.
