XML read Problem.

Hi
I have an XML. I want to bind its data to gridview

XML format is


 
    Chrysanthemum.jpg
    Jellyfish.jpg
    Koala.jpg
 
 
    Jellyfish.jpg
    Tulips.jpg
    Chrysanthemum.jpg
 


When I use
ds.ReadXml(xmlPath);
Then in dataset I got two tables
With the names "CategoryName" and "ImagePath"
"CategoryName" table have two columns "categoryName_Id", and "categoryName_Text"
"ImagePath" table have also two columns "categoryName_Id", and "ImagePath_Text"

Now how can I bind these tables to gridview. I want to bind Categoryname_text and Imagepath.
How can i do this.
When i try to join these tables using below method

DataRelation datarlt = new DataRelation("EquiJoin",ds.Tables["CategoryName"].Columns["CategoryName_Id"],ds.Tables["ImagePath"].Columns["CategoryName_Id"]);
        ds.Relations.Add(datarlt);
for this when i try to create relation then its says that relation already exist.

is there any simple solution of my problem?
