Hi,

You can probably save time and memory by directly passing the file
stream to the XMLParser:
stream := (FileStream readOnlyFileNamed: aFilenameString) readStream.

root := (XMLDOMParser  parse: stream) root.

A question: if you do you have a problem with the reading part (I mean
to compute the root), or is it spent in the follow up loops?

Cheers,
Doru
