Filtering columns in a .csv file v .xml file

Question

Hi everyone,
The following code fragment apparently creates a dataset from an xml file. The first line creates the dsStates dataset from an xml file called states.xm. The second line seems to be pulling in the list of cities into the dsCities dataset from the same xml file. I mean I assume this is what it's doing since it's accessing {dsStates::url} and then "/state/cities/city".
var dsStates = new Spry.Data.XMLDataSet("../../data/states/states.xml", "/states/state");
var dsCities = new Spry.Data.XMLDataSet("../../data/states/{dsStates::url}", "/state/cities/city");
My question is that since I'm not using xml as the source file for the dataset I'm creating but instead I'm using a .csv file, I'm wondering whether I can create two similar constructor functions like the above xml versions. I assumed that the first line would be as follows:
var dsTypes = new Spry.Data.CSVDataSet("data/types.csv");
This would bring in the data from a .csv file called "types.csv".
The question is though how would I access certain columns in this types.csv file so that I can filter them into the second dataset which would be called dsHospitals. I started off with the following line:
var dsHospitals = new Spry.Data.CSVDataSet("    ");
...but then since it's not xml is there are way to target these columns as it's done in the xml version. Or are there limitations with what I can do with a .csv file compared to xml files?
Would really appreciate any advice.

Thanks for the reply,
I've actually ended up using an xml file instead of a .csv due to the limitations.
I'm pulling in some xml files dynamically into a table and have based the code on the information at the following url:
http://labs.adobe.com/technologies/spry/samples/data_region/SpryPagedViewSample.html
My application is identical to the one in the above url except that instead of bringing in state and cities, I'm bringing in categories instead of the states and hospital names and addresses instead of the cities.
The example in the url uses an unordered list to display the names of the cities as in the following code:
<div spry:region="pvFacilities dsFacilities">
      <ul spry:repeatchildren="pvFacilities" spry:choose="choose">
            <li spry:when="{pvFacilities::ds_RowID} == {pvFacilities::ds_CurrentRowID}" spry:select="select" spry:selectgroup="page" spry:selected="selected" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::name}</li>
            <li spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::name}</li>
      </ul>
</div>
I needed to revise this since I'm not only displaying one item, ie. the city name as in the example, but instead I'll be displaying the full hospital details which would require that the information is inserted into a table. So I had to adapt the above code to work with a table and I came up with the following:
   <div id="privRegion" spry:region="pvFacilities dsFacilities">
  <table id="private" cellspacing="0" summary="A list of private hospitals">
<caption>Private Hospitals </caption>
<thead>
  <tr>
    <th id="name" scope="col"><a href="#">Name</a>
      </td>
    <th id="address" scope="col">Address</td>
    <th id="suburb" scope="col"><a href="#">Suburb</a>
      </td>
    <th scope="col">State
      </td>
    <th scope="col">Postcode</td>
    <th scope="col">Phone</td>
    <th scope="col">Fax</td>
  </tr>
  </thead>
  <tbody>
  <tr spry:repeatchildren="pvFacilities" spry:choose="choose">
    <td spry:when="{pvFacilities::ds_RowID} == {pvFacilities::ds_CurrentRowID}" spry:select="select" spry:selectgroup="page" spry:selected="selected" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Name}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Address}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Suburb}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::State}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Postcode}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Phone}</td>
    <td spry:default="default" spry:select="select" spry:selectgroup="page" spry:hover="hover" spry:setrow="pvFacilities">{pvFacilities::Fax}</td>
  </tr>
  </tbody>
</table>
</div>
When I test though, it's only bringing in the first row and even then, it's only bringing in the hospital name and then 19 of the phone numbers from other hospitals! Not exactly what I was aiming for?
Are you able to take a look at the following url to see where I may have gone wrong?

Really appreciate any help/advice.
