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">

                   <book ISBN = "978-1515074601">

                   </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?
