problem parsing xml (std.xml)

[Minas]

I'm trying to use std.xml to parse a small snippet of xml (for 
now).

This is my code:
[code]
void main(string[] args)
{
        string xmlText = "<?xml version=\"1.0\"?>\n" ~
                                         "<book>" ~
                                         " Test" ~
                                         "</book>";
        DocumentParser doc = new DocumentParser(xmlText);
        
        doc.onStartTag["book"] = (ElementParser el)
        {
                writeln("book opening found.");
        };
        
        doc.parse();
[/code]

My guess is that it would print "book opening found", but nothing 
is printed. I guess I made something wrong(?)
