Consider the following XML:

<dashboard>
    <locations>
        <location>
            <infowindowtab>
                <tab title="Location">
                    <![CDATA[ ... ]]>
		</tab>
                <tab title="Users">
                    <![CDATA[ ... ]]>
		</tab>
            </infowindowtab>
        </location>
    </locations>
</dashboard>

And that JavaScript (both simplified):

{{{

$.get(..., function(xml) {

$('location', xml).each(function() {

var content = [];

var infoWindowTabs = $('infowindowtab', this);

$('tab', infoWindowTabs[0]).each(function(k) {

// workaround for IE needed here, $(this).text() throws an error

content[k] = this.firstChild.data || $(this).text());

});

});

});

In that case IE fails on $(this).text() and throws an error (object does not support that property or method).
