I am writing a XML parser in D, because all the links with such libriraries are dead. And I have the following problem. When I parse the tags I set parent to each node (with pointer, basicly "something.parent=&somethingelse;"). When all is done address of objects seems changed and I get Access Violation if I use "node.parent". I tried to do the work with "cast(XMLnode*)somethingelse" instead of "&somethingelse" but it doesnt work neither. I could't find documentation about pointers in D and I'm stuck. Any ideas why is this?

Assuming your nodes are class objects and not structs it will work if you remove the &. Class objects in D have reference semantics (like Java, unlike C++) so using & takes the address of the reference not the object itself.

Seems that you want to use "node.parent*".

Try this! (I hope it works... I am no longer using this version)
I am going to re-design it soon.
