[Expat-discuss] XML Parse into Structure

[Nick MacDonald]

Vijay:

If you want an "in memory" representation of your XML file, you
probably don't want or need to use a SAX based parser like eXpat which
is event based.  You'd probably rather find a DOM based parser which
is expressly designed to build a Document Object Model (the DOM in the
name) in memory.  You could of course layer a DOM module on top of
eXpat, but I suspect that's a fair amount of work that has already
been done many times before, if you do some searching on Source Force
and other open source repositories I'm sure you'll find a lot of
examples.  The whole idea to use SAX is to be able to process a
document with minimal memory overhead... and thus to be able to handle
exceptionally large documents that would use too much memory if they
were loaded into memory all at once.  (And SAX would be faster if you
were just searching quickly inside a document... no overhead loading
into memory that parts you'd never use.)

Good luck,
  Nick
