Dynamically Processing Nodes

Hi Guys,

Building a 'Grid' component into my project.

I've run into a bit of a problem.
The layout of a grid is defined in a xml file.
At runtime, the grid should render based on the layout/config in the
xml file.

E.g.
<DataGrid
  Key="PromotionToNextGrade"
  Name="Promotion To Next Grade"
  Title="4.1. Promotions To The Next Grade">
  <Platform ID="Oracle"
    Sql="Select 'Hello World' from dual">
     <GridRows>
       <GridRow ID="RowOne"    Label="Row One"/>
       <GridRow ID="RowTwo"    Label="Row Two">
         <GridRow ID="RowTwoOne"    Label="Row 2.1"/>
         <GridRow ID="RowTwoTwo"    Label="Row 2.2"/>
         <GridRow ID="RowTwoThree"    Label="Row 2.3"/>
         <GridRow ID="RowTwoFour"    Label="Row 2.4"/>
       </GridRow>
       <GridRow ID="RowThree"  Label="Row Three"/>
       <GridRow ID="RowFour"   Label="Row Four"/>
     </GridRows>
     <GridColomns>
       <GridColomn ID="ColOne" Label="Col One"/>
       <GridColomn ID="ColTwo" Label="Col Two">
         <GridColomn ID="ColTwoOne" Label="Col 2.1"/>
         <GridColomn ID="ColTwoTwo" Label="Col 2.2"/>
         <GridColomn ID="ColTwoThree" Label="Col 2.3"/>
       </GridColomn>
       <GridColomn ID="ColThree" Label="Col Three"/>
       <GridColomn ID="ColFour" Label="Col Four"/>
     </GridColomns>
  </Platform>
</DataGrid>


Now, basic Grid functionality is easy.
However, I need to be able to build in Col spanning and Row spanning.
Here's a short example of what I require (Rowspanning).

<table border="1">
   <tr>
      <td colspan="3">Row 1</td>
      <td><input type="Text" size="3"></td>
   </tr>
   <tr>
      <td rowspan="3">Row 2</td>
      <td colspan="2">Row 2.1</td>
      <td><input type="Text" size="3"></td>
   </tr>
   <tr>
      <td rowspan="2">Row 2.2</td>
      <td>Row 2.2.1</td>
      <td><input type="Text" size="3"></td>
   </tr>
   <tr>
      <td>Row 2.2.2</td>
      <td><input type="Text" size="3"></td>
   </tr>
   <tr>
      <td colspan="3">Row 2.3</td>
      <td><input type="Text" size="3"></td>
   </tr>
</table>

Now, here's my iterator loop at this point in time.

<tr class="Dir::Iterate_Start.GridRows Dir::Iterate_Next.GridRows">
  <td class="Dir::Get_Data.GridRows.Label" valign="top">[ROW
LABEL]</td>	
</tr>
<tr class="Dir::Iterate_End.GridRows
Dir::Discard"><td>[DISCARD]</td></tr>

At the moment, I have Column and Row Objects.
A Column can be added other Columns. The same goes for Rows.

Now, once I process a row, I need to check if the current row contains
any children.
If it does, execute the same Iterator loop and process the child Rows.
Question is... how do I accomplish this...?

Urm....

Any one got any idea's?

Regards
KD
