Hi there, I use oxy_xpath funktion in CSS like this oxy_xpath("string-join(distinct-values(./..//DT/text()),',')") which works very well with an XML like this: <TD> <D> <DT>..</DT> <D> <D> <DT>..</DT> <D> </TD> But if D elements are in XML modules included with XInclude <TD> <xi:include href="d1.xml"/> <xi:include href="d2.xml"/> </TD> No result is found (as expected first). But if I execute XPath in Author mode the results I'm looking for are found. Is there any chance to get this or another oxy_xpath working with xincludes? This oxy_xpath call is the value of "values" property in a popupselection control. So I could implement my own custom control, but I want to avoid this, if possible. Thanks for any hints Markus
