I am using XML Beans to do schema validation and would like to add XPath
2.0 support. Presumably to get the full benefit of XPath 2.0 (I'm
specifically thinking of Schema Types), I'd need to use the latest
version of Saxon-SA.
Does XML Beans support the SA version as well as Saxon-B?
When can we expect an XML Beans *release* with Saxon 8.8 (SA and or B)
support? How stable are the current SVN versions (rev 500554?)?
Thanks

I just checked in (rev 500554) which will automatically download
saxonb8-8j.zip. Build and checkin tests seem to be working fine.
Don't forget to do an "ant clean.jars" and "ant deploy" to pick up the
new zip.

Could you try your test with Saxon 8.8.0.6 if it's not too much
trouble?
I have run XmlBeans with Saxon 8.8 a couple of months ago and it
worked
just fine.

After further investigation, it appears that the latter (XPath) bug
is
actually in the Saxon code
(net.sf.saxon.dom.NodeWrapper.getStringValueCS()
blindly appends the text values of all child nodes, regardless of
type).
The good news is that it looks like this bug was fixed somewhere
between
8.6.1 (the version supported by XmlBeans) and 8.8.0.6 (the current
version).
In 8.8.0.6, net.sf.saxon.jdom.NodeWrapper.getStringValueCS()
utilizes
the
org.jdom.Element.getValue() method, which complies with the Xml 1.0
specification by concatenating the values of all descendant text
nodes.
In the meantime, I guess we'll have to wait until XmlBeans becomes
synchronized with a more recent version of Saxon.

This apparent bug becomes more critical when evaluating XPath
expressions.
It appears that the same value returned by getTextValue is that
which
is
passed on to the Saxon XPath engine for evaluating element values,
as
the
following test shows:
String xml = "<element><!--A Comment-->999<?PI A Processing
Instruction?></element>";
XmlObject xo = XmlObject.Factory.parse(xml);
xo.selectPath("/element = 3");
This code snippet causes a Saxon ValidationException, with the
message:
Cannot convert string " A Comment 999A Processing Ins..." to a
double
If these results are a side-effect of misunderstanding, then we
would
greatly appreciate some insight. Otherwise, we're not sure how to
enter
them as bugs, other than to post on this forum.
Thanks,
Coram
