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
at test.Bookstore.setValue(Bookstore.java:74)
at test.Bookstore.main(Bookstore.java:108)
Regards
Patrizio

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");
