Hi Mateusz,
the DOMPrint example specifies the root element as the context node, not
the document node; so the correct behavior is for "bookstore" to return
an empty set, and "." to return the root element.

Hi,
Has anything changed between Xerces 3.0 and 3.1 regarding
resolution of XPath expressions?
It may seem strange, but very fundamental expressions like selecting
root element seems to work differently.
A very simple XML sample:
# cat bookstore.xml
<?xml version="1.0" encoding="utf-8"?>
<bookstore>
<book>
<title lang="eng">Harry Potter</title>
<price>29.99</price>
</book>
<book>
<title lang="eng">Learning XML</title>
<price>39.95</price>
</book>
</bookstore>
Here is quick test with the DOMPrint utility from Xerces C++ 3.1
# domprint -xpath=/bookstore bookstore.xml
<bookstore>
<book>
<title lang="eng">Harry Potter</title>
<price>29.99</price>
</book>
<book>
<title lang="eng">Learning XML</title>
<price>39.95</price>
</book>
</bookstore>
# domprint -xpath=bookstore bookstore.xml
#
Correct me if I'm wrong please, but shouldn't the second
command without explicit / anchor select root tree - it is evaluated
against the root anyway, right?
Best regards,
