Here's a brief list of the ones I have tried:
- NativeXML (http://www.simdesign.nl/xml.html)
- XMLVerySimple (http://blog.spreendigital.de/2011/11...der-and-writer)
- XMLParser (http://www.destructor.de)
- OmniXML (http://code.google.com/p/omnixml)
- SimpleXML (https://gitorious.org/delphi/simplexml)
- KDSXML (http://sourceforge.net/projects/kdsxml)
- SAX for Pascal (http://saxforpascal.sourceforge.net)
- DOM XML (the one that comes with delphi)

Some of them are DOM Model others are SAX, and some doesn't have a particular model. Big trouble of some is they are slow or have a big footprint. For the moment I haven't decide yet which one to use. Still need one very fast and able to manage really big xml files. BTW, only Omni and Delphi (MSDOMXML) has fluent access.
