Hi Jacob, thanks a lot for your support.
Two 'strange' thinks that I've noticed:
1) your example (and now also my example) is working simply adding only one
extra jar: saxon8-dom.jar.
That is at the end the jars in my path are:
saxon8.jar
xbean_xpath.jar
jsr173_1.0_api.jar
xbean.jar
saxon8-dom.jar
and also your example works even with only these jars.
But if I remove only saxon8-dom.jar I don't get any error but simply I see the
exception raised from our code:
java.lang.Exception: no result found for the given path expression
at test.XPathRepro.main(XPathRepro.java:47)
so I was expecting some other specific error from saxon distribution instead of
an empty XmlObject[] elems array.
In any case I'll use the above listed jars.
2) I added a small change to your example:
- a method for building the XmlObject instead of using the static docContent
string
public static XmlObject createDocument()
{
XmlObject document = XmlObject.Factory.newInstance();
XmlCursor cursor = document.newCursor();
cursor.toNextToken();
cursor.beginElement("bookstore", namespace);
cursor.beginElement("book");
cursor.insertElementWithText("id", "1");
cursor.insertElementWithText("author", "author1");
cursor.insertElementWithText("title", "title1");
cursor.toNextToken();
cursor.beginElement("book");
cursor.insertElementWithText("id", "2");
cursor.insertElementWithText("author", "author2");
cursor.insertElementWithText("title", "title2");
cursor.toNextToken();
XmlOptions opts = new XmlOptions();
opts.setSavePrettyPrint();
opts.setSavePrettyPrintIndent(4);
System.out.println("### createDocument:\n" + document.xmlText(opts));
return document;
}
- in your main
try {
XmlObject _document = XmlObject.Factory.parse(docContent);
XmlObject document = XPathRepro.createDocument();
but now the error is:
java.lang.Exception: Unsupported node type in DOM! 11 instance [EMAIL PROTECTED]
at test.XPathRepro.main(XPathRepro.java:45)
I compared the XPathRepro.createDocument to the docContent document but they
are equal.
(the same if I add the other jars resolver.jar and xmlpublic.jar)
I've attached your changed XPathRepro.java class.
Thanks again
Patrizio

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;. XPathRepro
<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>
START - PRINTING ELEMENTS
ELEMENT[0]-<xml-fragment xmlns:bs="http://www.bsource.ch/bs";>author2</xml-fragme
nt>
END - PRINTING ELEMENTS
Can you see if you get the same thing?
Thanks,
