A simple double for-loop would suffice perhaps:
for ( Relationship rel1 : startNode.getRelationships( relType1, dir1 ) )
{
Node node1 = rel1.getOtherNode( startNode );
for ( Relationship rel2 : node1.getRelationships( relType2, dir2 ) )
{
Node node2 = rel2.getOtherNode( node1 );
// Here you've got startNode,rel1,node1,rel2,node2 and it's just
// to pick properties from them.
}
}
