How do you do that? What call do you use?

xmlNodePtr nextSibling = node->next;

Then I check the node type and if it is a text node I get its content.

There is no such thing as "tail of the element <strong>" from the POV
of xmlTextReader.
The text node is merely the next node the cursor would be pointing at
calling xmlTextReaderRead.

Not sure how xmlTextReader is implemented, but my tests showed that I can get the element tail and compare 
with the value obtained from Python lxml. Actually, in the above example after correcting the XML file to be 
a valid DTBook I can parse correctly the entire file and get an element tail.
