That's something like the design as it has been.  I need to discuss this
further to be sure I understand what you are saying.

There are a couple of different struct definitions in the project,
and they all follow the same basic setup with type, next and parent.

When this data is accessed internally for example for writing an
XML file, they will be iterated over.  The code that iterates
over these struct instances in memory, will know what to do with
the data, based on the first entry in the struct, the type.

So, say I am at element 1, the root XML element.  The next element
is a child element and the element after that is a text element
(valid XML characters).

When the parser iterator goes over the internal representation,
it will for example do something like this:

if (((struct xml_header*)element).type == 3) {
   pseudo code: write stream, "<" + ((struct xml_element*)element).name
}

In addition to type==3, type can also be 4 and 5, XML attribute
and XML text.  So it looks like casting is necessary; and having
a union in the struct defines will restrict what's being pointed
to the chance of pointing to the wrong type of data is lower.

Well on the one hand it is nice to see some enthusiasm, on the other
hand, it was all a bit hard to follow.
