Method Detail

selectNodes

public java.util.List selectNodes(java.lang.Object arg0)
                           throws org.jaxen.JaxenException

Jaxen has some magic with its IdentitySet, which means that we can get different results depending on whether we cache ChildAssociationRef instances or not.

So, duplicates are eliminated here before the results are returned.
