## DataType Utility: DataType.XML.format()

The XML module of the DataType Utility allows you to take an XML document and convert it to a string.

View example in new window.

To output an XML document as a string, simply call the `format()` function of the DataType.XML class:

    YUI().use("datatype-xml", function(Y) {    var myXMLDoc = Y.DataType.XML.parse("&lt;myroot&gt;&lt;item type='foo'&gt;&lt;name&gt;Abc&lt;/name&gt;&lt;rank&gt;1&lt;/rank&gt;&lt;/item&gt;&lt;item type='bar'&gt;&lt;name&gt;Def&lt;/name&gt;&lt;rank&gt;2&lt;/rank&gt;&lt;/item&gt;&lt;item type='bat'&gt;&lt;name&gt;Ghhi&lt;/name&gt;&lt;rank&gt;3&lt;/rank&gt;&lt;/item&gt;&lt;/myroot&gt;");    alert(Y.DataType.XML.format(myXMLDoc));});

    YUI().use("datatype-xml", function(Y) {
        var myXMLDoc = Y.DataType.XML.parse("&lt;myroot&gt;&lt;item type='foo'&gt;&lt;name&gt;Abc&lt;/name&gt;&lt;rank&gt;1&lt;/rank&gt;&lt;/item&gt;&lt;item type='bar'&gt;&lt;name&gt;Def&lt;/name&gt;&lt;rank&gt;2&lt;/rank&gt;&lt;/item&gt;&lt;item type='bat'&gt;&lt;name&gt;Ghhi&lt;/name&gt;&lt;rank&gt;3&lt;/rank&gt;&lt;/item&gt;&lt;/myroot&gt;");
        alert(Y.DataType.XML.format(myXMLDoc));
    });

YUI().use("datatype-xml", function(Y) { var myXMLDoc = Y.DataType.XML.parse("<myroot><item type='foo'><name>Abc</name><rank>1</rank></item><item type='bar'><name>Def</name><rank>2</rank></item><item type='bat'><name>Ghhi</name><rank>3</rank></item></myroot>"); alert(Y.DataType.XML.format(myXMLDoc)); });
