Access meta data through the DOM

[chadmg]

Is there a way to access meta data through the DOM? Like document.meta['description'] or something?

This works as expected for me:

<script type="text/javascript">
<!--
function alertMeta(){
var a = document.getElementsByTagName("meta").item(0).content;
alert('The first meta tag on this page contains '+a+'.');
}
-->
</script>
