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.

I follow your suggestion Tudor, but it didn't reduce the total time expended on reading of data or the reduction was minimal.

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?

I not understood well your question. I got to compute almost everything that I needed, but for some reason, some data are lost when I iterate on root

In truth it can be correct, I messed up to interpret the data.

Cheers,
Doru
