Hi Patrizio, I've attached the source I used to run through the your xpath. I am getting a results back from this xpath/xquery statement. I'm curious if all of the required jars are on your path? Here is what my cmd to run the file looked like, it includes ALL of the jars (ie, more than required): D:\svn\apache\xmlbeans\trunk\repro\xpaths>java -classpath ..\..\build\lib\xbean. jar;..\..\build\lib\jsr173_1.0_api.jar;..\..\build\lib\saxon8.jar;..\..\build\li b\resolver.jar;..\..\build\lib\saxon8-dom.jar;..\..\build\lib\xbean_xpath.jar;.. \..\build\lib\xmlpublic.jar;. XPathRepro
Here is the output I get from running the attached file: D:\svn\apache\xmlbeans\trunk\repro\xpaths>java -classpath ..\..\build\lib\xbean. jar;..\..\build\lib\jsr173_1.0_api.jar;..\..\build\lib\saxon8.jar;..\..\build\li b\resolver.jar;..\..\build\lib\saxon8-dom.jar;..\..\build\lib\xbean_xpath.jar;.. \..\build\lib\xmlpublic.jar;.

Hi Jacob,
I've added the suggested line:
private final static String namespace =
"http://www.bsource.ch/bs";;
private final static String namespaceDeclaration = "declare namespace bs='" +
namespace + "';";
public void setValue (String path, String value) throws BookstoreException
{
XmlObject[] elems = null;
try
{
XmlOptions opts = new XmlOptions();
opts.setSavePrettyPrint();
opts.setSavePrettyPrintIndent(4);
System.out.println(document.xmlText(opts));
elems = document.selectPath(namespaceDeclaration +
"$this/bs:bookstore/book[author='author2']/author");
}
catch (Exception e)
{
throw new BookstoreException(e.getMessage());
}
if (elems.length == 0)
throw new BookstoreException("no result found for the given path
expression");
The output:
<bs:bookstore xmlns:bs="http://www.bsource.ch/bs";>
<book>
<id>1</id>
<author>author1</author>
<title>title1</title>
</book>
<book>
<id>2</id>
<author>author2</author>
<title>title2</title>
</book>
</bs:bookstore>
test.BookstoreException: no result found for the given path expression

Can we see the output of the following:
XmlObject[] elems = null;
// ADD this line
System.out.println(document.xmlText());
elems = document.selectPath(namespaceDeclaration +
"$this/bs:bookstore/book[author='author2']/author");
