[SalesForce] Apex: How to get all child element of an xml? – Parsing xml via XmlStreamReader

I am trying to parse an MSXML which is a response from a web services via XmlStreamReader.

The below code is the response from the web service:

<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40"> 
    <Worksheet ss:Name="Report"> 
        <Table> 
            <Row> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Project Name</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Project Code</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Project URI Report Setting</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Entry Date</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Actual Billable Hours (Selected Dates)</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Actual Non-Billable Hours (Selected Dates)</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">User Name</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">User Default Billing Rate</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">User Default Billing Rate (BC)</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Timesheet Start Date</Data> 
                </Cell> 
                <Cell ss:StyleID="Default"> 
                    <Data ss:Type="String">Timesheet End Date</Data> 
                </Cell> 
            </Row>
        </Table>
    </Worksheet>
</Workbook>

I wanted to get all the cell(s) in every row

Here is my code on how do I parse the response (assume that reportXML is the response):

 class Cell {
      string data { get; set; }
 }

 XmlStreamReader xsr = new XmlStreamReader(reportXML);

 while(xsr.hasNext()) {
      if (xsr.getEventType() == XmlTag.START_ELEMENT) {
           if (xsr.getLocalName() == 'Row') {
                Cell cell = parseCell(xsr);
                system.debug(cell);
           }
      }
      xsr.next();
 }

 Cell parseCell(XmlStreamReader reader) {
      Cell cell = new Cell();

      while(reader.hasNext()) {
           if (reader.getEventType() == XmlTag.END_ELEMENT) {
                break;
           }
           else if (reader.getEventType() == XmlTag.CHARACTERS) {
                cell.data = reader.getText();
           }

           reader.next();
      }

      return cell;
 }

The problem is I am only getting a single cell and not all the cell.
Cell:[data=Project Name] is the only data from the debug logs which I think the first column cell only.

Why? and what is the code that bugs the logic for displaying all cell data?

EDIT:

I changed the 'Row' into 'Cell' on the condition for comparing localName.
And I am now getting all the cell but how can I check if this belongs to the specific row ?(e.g., row at index 2).
