Hi, I have this code:

 

<asp:XmlDataSource runat="server" id="xmlDS" XPath="envelope" >
          <Data>        
            <envelope>
                <header>
                    <version>1.5.1</version>
                    <timestamp>20080627150909</timestamp>
                </header>
                <response type="details" product="hotel">
                    <shop value="false"/>
                    <golf value="true"/>
                    <radio value="false"/>
                </response>
          </envelope>
       </Data>
  </asp:XmlDataSource>
              
    <asp:repeater ID="repeater1" runat="server" DataSourceID="xmlDS" >
        <ItemTemplate>
            <asp:Label ID="value" Runat="server" Text='<%# XPath("response/*/@value") %>' /><br /> 
        </ItemTemplate>
    </asp:repeater>

 As you can see in the XPath expression, I want repeater to write the value attribute of each children of response element. But it writes only the first value!! (the "shop" value).

What's wrong in the XPath expression?

Thanks 

 

 

Is there any reason you can't use 3 separate Label controls?

 

<asp:Label ID="shopLbl" Runat="server" Text='<%# XPath("response/shop/@value") %>' />

<asp:Label ID="golfLbl" Runat="server" Text='<%# XPath("response/golf/@value") %>' />

<asp:Label ID="radioLbl" Runat="server" Text='<%# XPath("response/radio/@value") %>' />

If that's no good you should probably explain how you would like the result to look

I could do that, but response children are almost 60! So I think it's better to write only one label (and make it repeat by the repeater) rather then write 60 label :)

Well the reason I asked you to specify how you would want the result to look/be formatted is because you can construct a value for the label programatically, that is a combination of those 3 XML attributes... but how would you want it to look ie: "shop, golf, radio, "

It sounds to me like what you're trying to accomplish would be the simplest through a GridView where you can just use Bound Fields and specify that attribute that each field is for

IE:

         <asp:GridView ID="GridView1" runat="server" DataSourceID="xmlDS">
            <Columns>
                <asp:BoundField DataField="response/shop" HeaderText="Shop" />

                <asp:BoundField DataField="response/golf" HeaderText="Golf" />
               

                etc
                etc
            </Columns>
        </asp:GridView>

Actually scratch that, you can do it this way to make it super easy

       

        <asp:DataList ID="DataList1" runat="server" DataSourceID="xmlDS">
            <ItemTemplate>
                <table>
                    <tr>
                        <td>
                            <%#XPath("response/shop/@value")%>
                        </td>
                        <td>
                            <%#XPath("response/golf/@value")%>
                        </td>
                        <td>
                            <%#XPath("response/radio/@value")%>
                        </td>
                    </tr>
                </table>
            </ItemTemplate>
        </asp:DataList>
        <asp:XmlDataSource runat="server" ID="xmlDS" XPath="envelope">
            <Data>    
                <envelope>
                <header>
                    <version>1.5.1</version>
                    <timestamp>20080627150909</timestamp>
                </header>
                <response type="details" product="hotel">
                    <shop value="false"/>
                    <golf value="true"/>
                    <radio value="false"/>
                </response>
          </envelope>
            </Data>
        </asp:XmlDataSource>

 Ok, thanks drocco :)

Now I'd like to visualize only the elements which have "true" in their value attribute, so, for example, I'd like to have this output:

golf

Beacuse golf is the only one with true value.

PS: Is there any way to change the visualization of the element? For example instead of "golf" I would visualize "we have golf"

So the FINAL issue is: take the elements which have attribute value="true" and, if possible, change their name at runtime.
 

I think I have a better understanding of what you're try to do now

You're making 60 elements and you just want to use the ones that have a value of true so you're just inflating the size of your XML file when you may be better off just making a <description>Short description of the hotel</description> and calling it that way

In other words, you might think of other ways to get a similar result because this might be more trouble than it's worth

#1 you don't want to have We have this on the page 60 times and if you have We Have followed by a string of what they do have, it may not be grammatically correct... We golf, shop, radio or We have a golf, shop, radio doesn't make sense

Hi Andrew-Ita,

You can write some code.

 

   protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void DataList1_Load(object sender, EventArgs e)
    {

    }
    protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        PlaceHolder ph = e.Item.FindControl("PlaceHolder1") as PlaceHolder;
        
        if (ph != null)
        {
            
            IXPathNavigable nav = e.Item.DataItem as IXPathNavigable;
            XPathNavigator xnav = nav.CreateNavigator();
            XPathNodeIterator iter =  xnav.Select("response/*");
            while (iter.MoveNext())
            {
                string str = iter.Current.Name;
                XPathNavigator attnav =  iter.Current.CreateNavigator();
                attnav.MoveToFirstAttribute();
                string atti = attnav.Value;
                if (atti == "true")
                {
                    LiteralControl liter = new LiteralControl();
                    liter.Text = str + "is ok";
                    ph.Controls.Add(liter);
                }
            }
        }
    }
