Count all <a> on html page

Question

I want to get all the <a> tags from an Html page with this JavaScript method:

function() {
    var links = document.getElementsByTagName('a');
    var i=0;
    for (var link in links){i++;}
    return i;
}

And i noticed it's won't return the correct number of a tags.

Any idea what can by the problem?

Any idea if there is any other way to get all the href in an Html ?

Edit

I tried this method on this html : http://mp3skull.com/mp3/nirvana.html . And i get this result:"1". but there are more results in the page.

You don't need a loop here. You can read length property.

function getACount() {
    return document.getElementsByTagName('a').length;
}
