what about std.xml for starters ?
it is criticized and in need of overhaul though.

I've used http://vipbase.net/xmlparser/ and I liked it; here's the
description:

XmlParser is a lightweight open source C++ library based on Apache's Xerces
C++ Parser <http://xml.apache.org/xerces-c/>. XmlParser contains only two
files (one .cpp and one .h) and provides simple API for parsing XML files.
XmlParser supports charsets such as GB2312.

it's only 2 files and should be easy to port to D.

Tango.xml is know to be pretty good. std.xml isn't that great 
performance and API wize. I know vibe propose something, but I am 
unsure how good it is.

Vibe.d don't have XML module, only Json and Bson.

The XML package in Tango is the best. Still works even if it's not 
maintained. It won't compile with the latest beta of DMD but it does 
compile with the latest version, 2.062. I'll have dependencies on Tango 
so I'll probably maintained if no one else does it.

I concur. It works very well for my DOM parser needs.
Filtering on XPath makes it very easy to do anything.

You should give a try to dom.d by adam ruppe:

https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff

You just need dom.d and charactersencoding.d

I don't think it would work best for xmpp though because dom.d 
needs the entire file before it can parse, and xmpp is a stream 
of data.

AFAIK, Tango's xml is the same.

I just decided to write a quick stream like thing, to see if I 
can, and it actually kinda works.

My dom.d is still NOT an ideal choice for xmpp, I was just 
wondering if I could do this easily and figured I'd share the 
results.

dom.d
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/dom.d

also needs characterencodings.d from that same github.

===

import arsd.dom;
import std.stdio;

void main() {
	auto document = new Document();
	document.eventObservers ~= delegate(DomMutationEvent event) {
		if(event.operation == DomMutationOperations.appendChild) {
			auto element = event.related;
			if(element.tagName == "cool")
				writeln("GOT: " ~ element.toString());
		}
	};

	document.parseStream(new Utf8Stream(delegate string() {
		return readln();
	}, delegate bool() {
		return stdin.isOpen;
	}), true, true);
}
===


$ dmd streamtest.d dom.d characterencodings.d

<test>
<cool>sweet</cool>

</test>



The parse function expected a complete string, and I didn't 
signficantly modify it. Instead I created a class Utf8Stream that 
overloads enough operators that it can pretend to be a string, 
but one that can fetch more data when its length is checked and 
it is close to the last index fetched (the parse function checks 
data.length often to avoid going out of bounds, and it fetches 
chars by opIndex one at a time, so it works here, but wouldn't 
likely work elsewhere. Heck it might even break with non-ascii 
input, I haven't tried that yet)

So yeah pretty hacky, but since it internally builds the tree and 
fires off these mutation event things, you can hook into that and 
react as it is built, accomplishing the task at hand, more or 
less.

But since it is still building a big old dom and appending 
strings internally, it will be a bit of a memory hog as time goes 
on, and performance may not be great.

It also works better in strict mode (The true, true on the parse 
function argument list does this) than garbage mode when 
streaming.



Like I said, dom.d still isn't my first choice for xmpp or any 
other enormous xml parsing task, but hey it kinda works and is 
fairly convenient so if this looks useful to you, have fun!

I suggest you check the XMLP library by Michael Rynn. I tried XML 
processing with D, so I don't know how good the different 
libraries are, but XMLP is on the review queue, which means it's 
highly possible it will become Phobos' standard XML library, and 
when that happens you will have an easy migration.

That is a good point. I suppose I'll take a look at that and
Tango's XML package.

Some time ago, I contacted the xmlp developers about this type of 
parsing. They made some changes and shared these links with me.

Additional requirement: You need a streaming XML parser (aka 
event-based or SAX).

Is it Open Source? I was thinking about doing something similar.

Tango has a SAX parser.
