I am new to java and I am trying to create an XML document and clone a specific node (minus the textnode) of this document over and over again. Someone answered me and said that I should subclass the node and override the cloning. So my question is what is sub-classing?
@Charlie Martin has explained what subclassing means.
However, it is not clear that you’ve been given good advice. If you are creating the XML document by assembling a DOM in memory, a better approach would be to create a helper class with static methods that perform the sequence of DOM node operations that you need to do.
