I think difficulty however can be lessened by how the object is structured. I've been thinking that it needs to be one more level of abstraction, that is to say that each step in the object tells you what elements, attributes, namespaces, element name ,defaultNamespace, and textnodes are contained at that step. With textnodes referenced inside the elements block so that one can maintain their position. Child1: make object![ Name: "h:p" Elements: [t1 "h:p" "a" t2 "n:p"] Attributes: ["class" "style"] Namespaces: ["xmlns:h=''"] defaultNamespace: "" att1: "ParaStyle1" att2: "position:relative;" t1: "here's some text" t2: "hi" Child1: make object![ Name: "h:p" .... and so on and so on ] ] It is definitely not as elegant as just using Rebol path to navigate to /p/p but I think the abstraction offered here is necessary in order to handle all the possible weird textnode, namespaceing issues.
