Download the HTML table on my desktop area in XML format on click of a button

I am learning jquery and I am stuck with a functionality. I would like to download this table on my desktop area in XML format on click of a button using HTML5/javascript/jquery. I don't want to involve any server. Please help with the entire code. Thanks.

<script>
var table8_Props = {
col_0: "select",
public_methods: true
};
var tf8 = setFilterGrid("table8", table8_Props);
</script>
