Maarten is correct, without the Document you'll get a null pointer
exception from XPath.

Hi Andreas,
if I remember correctly (I don't have access to the sources from
here), the nodes have to be part of a document if you execute an XPath
query on them.
hope this helps
Hello,
I have parsed an OpenOffice.org document (content.xml) and tried to get
a
list of all "table:table" elements. Therefore I used the following code.
Document doc = reader.read(myFile);
List list1 = doc.selectNodes("//table:table");
Element body =
(Element)doc.selectSingleNode("/office:document-content/office:body").detach();
List list2 = body.selectNodes("//table:table");
The first call of selectNodes works fine. list1 contains all
"table:table"
elements. But when I detach the "office:body" element (is a child of the
root element) and call the selectNodes from body I always get an empty
list. But all "table:table" elements are descendants of "office:body".
So
the result should be the same.
Does selectNodes work correctly only on nodes that are part of an
existing
document and not on nodes that are d etached from an document? That's
the
only difference I can see.
Kind regards,
Andreas
