如何在不使用XML解码器的情况下解码XML文件？

I have a XML file which was encoded using java.beans.XMLEncoder. I cannot use java.beans.XMLDecoder to decode it, as the class of encoded object is not present in my project. Is there a way to obtain values in xml without using java.beans.XMLDecoder, xmlDecoder.readObject() method ?I have a XML file which was encoded using java.
