Hi Jacob, I was using eclipse but just now I switched to command line as your test, to see if there is any difference.
So:
1) at source level the same changes as you
try {
//XmlObject _document = XmlObject.Factory.parse(docContent);
XmlObject document = XPathRepro.createDocument();
2) compilation
C:\projects\workspace\xml\xmlcursor>javac -d classes -classpath
.\lib\xbean.jar;.\lib\jsr173_1.0_api.jar;.\lib\resolver.jar;.\lib\saxon8.jar;.\lib\saxon8-dom.jar;.\lib\xbean_xpath.jar;.\lib\xmlpublic.jar;.
src\test\XPathRepro.java
C:\projects\workspace\xml\xmlcursor>dir /s classes
...

I don't understand why ...
About your additional question, there is no schema (XSD) behind it.
Just I started to use xmlbeans framework and I'm interested on using XmlObject
& XmlCursor classes.
So I tried to use XmlCursor to build a new xml document and document.selectPath
to extract values (and then changing some values in the xml document ...).
The full stack trace of the error is:

Hi Patrizio,
I'm not sure where you are getting that error from. When I run the src
you gave me (with only textual and package difference) everything
works fine for me.
My changes were removing the package declaration and commenting out
the other XmlObject . For Example,
// XmlObject _document = XmlObject.Factory.parse(docContent);
My output is below.
What kind of environment are you running in. Is it an IDE?
Also, for general programming purposes, it seems like your XML
instance has some kind of shape, Is there a schema (XSD) behind it. If
there is you could just use the simple POJO (getters/setters) API for
manipulating this XML.
Thanks,
-Jacobd
