I observe that this is not the case. And if an attribute contains &amp; it is
turned into &amp;amp; What is the best way to receive the same output for both.
The code that follows outputs

Attr: What &amp;amp; Up
Elem: What &amp; Up



*testfile.xml:*

<?xml version="1.0" encoding="utf-8"?>
<Tests>
	<Test thing="What &amp; Up">What &amp; Up</Test>
</Tests>


*test.d:*

import std.stdio;
import std.xml;

void main() {
	auto file = "testfile.xml";

	auto s = cast(string)std.file.read(file);

	auto xml = new DocumentParser(s);

	xml.onStartTag["Test"] = (ElementParser xml) {
		writeln("Attr: ", xml.tag.attr["thing"]);
	};

	xml.onEndTag["Test"] = (in Element e) {
		writeln("Elem: ", e.text);
	};
	xml.parse();
}

Clearly std.xml is buggy.  Correct behaviour would be

Attr: What & Up
Elem: What & Up

The xml parsing code in D2 could use some love and care.  It was originally
written by Janice who seems to have dropped off the face of the planet.  It's
little more than a first draft with serious performance problems and several
important bugs.

Anyone want to volunteer to invest some time in improving it?

Later,

I don't mean to shoot down the idea?  But Tango already has three XML
parsers which are, like, the fastest.  Ever.

I'm just saying, it'd seem like pointless duplication of effort with
such parsers _already available_.  If it could be relicensed, I'd say
that's the best route.

Relicensed and separable from the rest of Tango.  It's been way too long since I
looked at that code in Tango to recall any of its details.

Basically I agree with you on this one. :)

Can't just phobos dissappear? :-(

Like... it must be the first standard library in the world that's 
developed by 3-5 people.
