Re: Fastest XML Parser ?

in reply to Fastest XML Parser ?

XML::Bare seems to be pretty fast. I've used it for interfacing with an XML based API to an Oracle DB, and I must say I was very pleased with its performance (and ease of installation — no external library dependencies).  It's not perfect in every respect, but if your XML is simple and predictable, it might be worth giving it a try...

(BTW, there's some benchmark results against other modules at the end of the module's POD.)

Wow, very fast; thnx for the pointer.

BUT....the output is very densebloated. Every leaf node is a full hash, and it tries to preserve comments and attributes. Which is great if the output is going to be turned back into XML...but I just want the values/attributes keyed by their names, so I can create a reasonably compressed piece of JSON to send to the browser.

I'm taking a stab at patching it w/ a "compact" option to achieve that and see how it behaves.

Update:
Hacked it up to support both a compact mode, and a to_json() method;
Results:
XML::Simple + XML::LibXML + JSON::XS : ~0.6 sec
XML::Bare w/ hacks: 0.04 sec (yes, 40 millisecs)

I think I've found my favorite XML parser 8^))

I'm interested in doing to same thing (convert XML to JSON quickly) and your solution looks very interesting.

Would you mind posting it somewhere for the whole world to enjoy? :-)
