Chrome & Safari - Not answering inArray correctly

Chrome & Safari - Not answering inArray correctly

I'm using inArray() to check an XML tag against an array called status[].  If the result != -1, then do one set of instructions, else, the item is 'available' so do another set of instructions.


Each entry of my XML document has a <status> tag, which will contain one of 3 values, or a 4th option 'available'.  I have an array setup called status['sold', 'pending', 'reduced'].  If the <status>.text() is one of these 3 values, then we'll get the array position, if it's 'available' we should get -1.


When I run this in Firefox (3.6) & IE (8.0 or Comp Mode) it works fine.  However, when I run this in Safari (4 or 5) & Chrome, it returns the value -1 for each of the entries.  The 3rd, 5th, & 7th entries are all set to <status> 'sold' and inArray() should be returning a 0.


Code:
    <home id="" model="" vin="">
        <status>available</status>
    </home>





     <home id="" model="" vin="">
        <status>sold</status>
    </home>

var status = ['sold', 'pending', 'reduced'];

$(xml).find("home").each(function(xml){
      var statusVal = $(this).find("status").text();
      var statusN = ($.inArray(statusVal, status));
});


Can someone explain why this happens?  How can I fix my page?
