Experimental xml set up

[Begah via Digitalmars-d-learn]

To load up 3D models in my application, i decided to use the 
COLLADA model format, to do that i need to be able to extract 
information out of an xml file.

Since std.xml is going to be deprecated eventually, is opted to 
try and use std.experiment.xml.

So i created a test project and added this dependency to dub.json 
:
"std-experimental-xml": "~>0.1.2"

I then tried and compiled the exemple i found on the xml wiki at 
https://lodo1995.github.io/experimental.xml/std/experimental/xml.html

Code :
// Made sure I imported Everything
import std.experimental.xml.appender;
import std.experimental.xml.cursor;
import std.experimental.xml.dom;
import std.experimental.xml.domimpl;
import std.experimental.xml.domparser;
import std.experimental.xml.dtd;
import std.experimental.xml.faststrings;
import std.experimental.xml.interfaces;
import std.experimental.xml.lexers;
import std.experimental.xml.parser;
import std.experimental.xml.sax;
import std.experimental.xml.validation;
import std.experimental.xml.writer;
import std.experimental.xml.legacy;
import std.stdio;

void main() {
	string input = q"{
		<?xml version = "1.0"?>
		<books>
		   <book ISBN = "078-5342635362">
			   <title>The D Programming Language</title>
			   <author>A. Alexandrescu</author>
		   </book>
		   <book ISBN = "978-1515074601">
			   <title>Programming in D</title>
			   <author>Ali Çehreli</author>
		   </book>
		   <book ISBN = "978-0201704310">

		   </book>
		</books>
	}";

	// the following steps are all configurable
	auto domBuilder =
		input
	   .lexer              // instantiate the best lexer based on 
the type of input
	   .parser             // instantiate a parser on top of the 
lexer
	   .cursor             // instantiate a cursor on top of the 
parser
	   .domBuilder;        // and finally the DOM builder on top of 
the cursor

	// the source is forwarded down the parsing chain and everything 
is initialized
	domBuilder.setSource(input);

	// recursively build the entire DOM tree
	domBuilder.buildRecursive;
	auto dom = domBuilder.getDocument;

	// find and substitute all matching authors
	foreach (author; dom.getElementsByTagName("author"))
	   if (author.textContent == "A. Alexandrescu")
		   author.textContent = "Andrei Alexandrescu";

	// write it out to "catalogue.xml"
	auto file = File("catalogue.xml", "w");
	file.lockingTextWriter
		.writerFor!string   // instatiates an xml writer on top of an 
output range
		.writeDOM(dom);     // write the document with all of its 
children

	readln();
}

When trying to compile, i get the following error :
Error: no property 'lexer' for type 'string'

There are also a lot of variable types not recognized by the 
compiler.

Is the wiki example completely outdated or am i missing something?
