Re: XML Data Parsing

Tudor Girba-2
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

Re: XML Data Parsing

Andre Hora
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,
