I'm trying to extract the StateLongName and StateShortName values from the xml below.

I know there has to be a simple elegant way to do this with jQuery.

<NewDataSet>
  <Table>
    <StateLongName>Alabama</StateLongName>
    <StateShortName>AL</StateShortName>
  </Table>
  <Table>
    <StateLongName>Alaska</StateLongName>
    <StateShortName>AK</StateShortName>
  </Table>

...elments removed for brevity

</NewDataSet>

Here's what I've tried.

Load the xml from above into a Javascript variable name xml.

Try #1

$(xml).find("TABLE").each(function()
{
  var stateName = $(this).find("StateLongName").innerText;
  var stateCode = $(this).find("StateShortName").innerText;
});

Try #1 doesn't find anything and never goes inside to load the stateName and stateCode variables.

Try #2

$(xml).find("StateLongName").each(function()
{
  var stateName = $(this).find("StateLongName").innerText;
  var stateCode = $(this).find("StateShortName").innerText;
});

Try #2 does find matches, however the stateName and stateCode are left undefined.

Try #3

$(xml).find("StateLongName").each(function()
{
  var stateName = $($(xml).find('StateLongName').parent()[0].innerHTML)[1].data;
  var stateCode = $($(xml).find('StateLongName').parent()[0].innerHTML)[5].data;
});

Try #3 works but there has to be a better way. Please enlighten me.

Thanks for you time!
