Just a quick note that I have just released version 4.3 of Objective-
XML, an efficient and convenient XML framework for Cocoa (Touch):
http://www.metaobject.com/downloads/Objective-C/Objective-XML-4.3.tgz
From the Readme:
Objective-XML is an XML processing framework for Objective-C. It
provides both highly efficient implementations of existing DOM and SAX
APIs as well as a new Message oriented API for XML (MAX).
MAX
The Message Oriented API for XML is a streaming API similar to SAX
with two important innovations. First, it translates from XML element
names directly to specific Objective-C messages, so clients don't have
to do string matching on the tag names. Second, it handles most of
the book-keeping associated with tree-building, while giving to the
client full control over what kind of tree to build, including none at
all.
MAX's flexibility allows clients of the parser to easily create DOM or
SAX style parsers, or freely mix elements as needed. In the tradition
of eating your own dog food, Objective-XML's SAX and DOM parsers are
both built on top of MAX.
SAX
Objective-XML's SAX parser is plug-compatible with Cocoa's
NSXMLParser, but performs much faster while using far less memory.
How much faster and how much less memory? Usually around an order of
magnitude on both counts.
DOM
A DOM is an inherently memory intensive way of representing XML
documents. So although Objective-XML's DOM is relatively efficient
both in memory and CPU usage, it is not just much more efficient to
build a MAX parser to your own objects, it is usually easier, too.
