xpath behaves differently in CS4?

Using the bookstore example from the Tools guide I get different results using this code with CS 3 and CS4

var Docdatafile=File(''/test.xml'');

var myResult = Docdatafile.open(''r'', undefined, undefined);

var temp = Docdatafile.read();

var docdata=new XML (temp);

book=docdata.xpath(''//title[@lang]'');

alert(book);

CS3 gives me ''enenenen'' which is what I expect whereas CS4 returns the complete title object. I am not completely sure what xpath is supposed to return in this case. (Actually I need to get the name of a publication where name is an attribute of a publication node.)

To formulate differently: Is there a way to get the attribute name out of an XML object with xpath that works the same way in CS3 and CS4?

Thank you,

Ralf

book=docdata.xpath(''//title/@lang'');

seems to work for both CS3 and CS4.
