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?

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

Hello, you can try: ... stream := StandardFileStream readOnlyFileNamed: aPath. root := (XMLDOMParser parse: stream) root. ...
in addition you can read from a url: ... stream := HTTPClient httpGet: 'http://rss.cnn.com/rss/edition_world.rss'. root := (XMLDOMParser parse: stream) root. ...
regards,
