We know we have it since we made it this far.

Look for elements in ELEMENT block.

All elements are of the form: "<E ID="#"> ... </E>", with ? being the element type. Read the ID field first.

Since all edge data is one big text block, we need to accumulate all TEXT data and then parse it. This approach effectively skips all comments or other node types since we only care about the edge list. We cannot handle missing edge numbers as we could with missing element numbers due to the text block format.

Now parse out the edges, three fields at a time.

We know we have it since we made it this far.

Look for elements in ELEMENT block.

All elements are of the form: "<? ID="#"> ... </?>", with ? being the element type.

These should be ordered.

Read id attribute.

Read text element description.

Parse out the element components corresponding to type of element.

Create a TriGeom to hold the new definition.

Create a QuadGeom to hold the new definition.

Keep looking
