Re: XML Data Parsing - Moose-dev

Correcting what I told...

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.
