Back
no one is more surprised than I that I have a recommendation... or at
least some useful information (I was sure I was gonna be a rigger... not
a programmer... wrong again).
I took a quick look at the Chilkat XML docs to make sure. And I think
that particular parser is a DOM style parser. Which has repercussions.
Stepping back a second.
According to w3c there are two basic types of XML parsers (well, two
that they foresaw and wrote about). DOM type and SAX type.
DOM (Document Object Model) type parsers will parse the entire XML file
and load it into memory to be manipulated like a node tree.
SAX (Simple API for XML) type parsers are event driven. As an XML
stream is read, it fires off callbacks to your code to do with the data
what you will.
(note: in most cases a DOM style parser is written on top of a SAX style
parser. It uses the SAX parser to build the DOM tree and then hands it
over to you.)
Without a doubt, DOM parsed XML docs are a lot more fun and intuitive to
work with. However, since the entire document ends up loaded into
memory in most cases, its not always reasonable to use a DOM style
parser on large data sets. And since we are talking about 3d here...
large data sets are a possibility (dare I say likely?).
So, if you're looking for a good solid XML base to work off of for
working in XSI, I'd look to something that has both types of parsers to
work with. Though I'm kinda new to the ActiveX world... so I don't have
any specific recommendations as to what might satisfy said suggestion.
Though I'd be willing to bet Python has a number of good XML parsers
available.
