XML Data Parsing - Moose-dev

 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. Is about it your question?

...
  Cheers,
 Doru

  HI!

 I have a optimization problem to solve and I would want some hint of you.

 I am using the xml framework to work with data from xml file, and the
 reading of the data is consuming much time.
 In my code I do something as:

 | stream root |

 stream := (FileStream readOnlyFileNamed: aPath) contentsOfEntireFile
 asString..
 root := (XMLDOMParser  parse: stream) root.

 root allElementsNamed: 'something' do:[ :eachB|
          eachB attributeNodes attributeValueAt: 'list'
          ...
          eachB allElementsNamed: 'another something' do:{ :eachD|
            .  eachD attributeNodes attributeValueAt: 'element'
               ..
         ]
 ]

 I know such iteration like that take much time to be executed when the  file
  read is big. There is a another manner to read
the data from xml file  that
  consume less time as possible? Or have someone an
idea to improve this  code?

 Julio
