troubles executing XmlObject.selectPath
Hi all,
I'm using xmlbeans-2.2.0 and saxonb8-6-1 and I'm trying to use the
XmlObject.selectPath function.
Here my xml document:
<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>
generated using XmlCursor object in the following way:
1) in Bookstore constructor
document = XmlObject.Factory.newInstance();
cursor = document.newCursor();
cursor.toNextToken();
cursor.beginElement("bookstore", namespace);
2) when I add a book to my bookstore object
public void add(Book book) throws BookstoreException
{
if (book == null) throw new ...
if (document == null) throw new ...
id++;
book.setId("" + id);
cursor.beginElement("book");
cursor.insertElementWithText("id", book.getId());
cursor.insertElementWithText("author", book.getAuthor());
cursor.insertElementWithText("title", book.getTitle());
cursor.toNextToken();
}
Now I'm trying to run the following piece of code:
XmlObject[] elems = null;
...
elems =
document.selectPath("$this/bs:bookstore/book[author='author2']/author");
if (elems.length == 0)
throw new BookstoreException("no result found for the given path
expression");
but selectPath returns zero elems !
I've checked the xpath expression
(/bs:bookstore/book[author='author2']/author) with XMLSpy against the
same xml document and the xpath expression seems to be correct ... so I
don't understand because selectPath fails to return the results.
Could you give me please some hints on that ?
Regards
Patrizio

Can I suggest using "declare namespace" to bind the prefix "bs" to the
current namespace inside the XPath? I doubt it would know what the
prefix means....
