Compile error "class Poco::XML::Element' has no member named 'getNodeByPath"

Hello everyone,

I am new to openFrameworks, i m trying to make it work with QT, but i m getting an error. I solved all the errors like(gst.h,glib.h etc) but i was not able to solve this one.
When i try to compile an example, i am getting one error. I will be posting the error i got below.

    /home/kalyan/openFrameworks-master/libs/openFrameworks/utils/ofXml.h:204: error: 'class   Poco::XML::Element' has no member named 'getNodeByPath'
     Poco::XML::Element *e = (Poco::XML::Element*) element->getNodeByPath(path);

I hope some one will help me in this issue.
Thanks in advance
