Hi,

I have a XML file that I want to load all the child elements(TopicName) into a Dropdownlist.

Thanks
<content type="application/xml">

You can use xmldatasource.

DropDownList ID="DropDownList1" runat="server" DataSourceID="myXML" DataTextField="TopicName" DataValueField="TopicId" />
 
<asp:XmlDataSource ID="myXML" runat="server" DataFile="~/myXMLFile.xml"  XPath="xpath of your element" />

1) You need to fix that XML document I edited that for you
2) Use the code below I fixed for you, I tested it and it works

In ASPX:

<asp:DropDownList ID="DropDownList1" runat="server">
        </asp:DropDownList>

New XML:

<content type="application/xml">
    <CatalogItems xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="sitename.xsd">
        <CatalogSource Acronym="ABC" OrganizationName="ABC Corporation" />
        <CatalogItem Id="3212" CatalogUrl="urlname">
            <ContentItem xmlns:content="sitename.xsd" TargetUrl="url">
                <content:SelectionSpec ClassList="" ElementList="" />
                <content:Language Value="eng" Scheme="ISO 639-2" />
                <content:Source Acronym="ABC" OrganizationName="ABC Corporation1" />
                <content:Topics Scheme="ABC">
                    <content:Topic TopicId="1" TopicName="Marketing1" />
                    <content:Topic TopicId="11" TopicName="Coverage1" />
                </content:Topics>
            </ContentItem>
        </CatalogItem>
    <CatalogItem Id="3212" CatalogUrl="urlname">
        <ContentItem xmlns:content="sitename.xsd" TargetUrl="url">
            <content:SelectionSpec ClassList="" ElementList="" />
            <content:Language Value="eng" Scheme="ISO 639-2" />
            <content:Source Acronym="ABC" OrganizationName="ABC Corporation2" />
            <content:Topics Scheme="ABC">
                <content:Topic TopicId="2" TopicName="Marketing2" />
                <content:Topic TopicId="22" TopicName="Coverage2" />
            </content:Topics>
        </ContentItem>
    </CatalogItem>
    <CatalogItem Id="3212" CatalogUrl="urlname">
        <ContentItem xmlns:content="sitename.xsd" TargetUrl="url">
            <content:SelectionSpec ClassList="" ElementList="" />
            <content:Language Value="eng" Scheme="ISO 639-2" />
            <content:Source Acronym="ABC" OrganizationName="ABC Corporation3" />
            <content:Topics Scheme="ABC">
                <content:Topic TopicId="3" TopicName="Marketing3" />
                <content:Topic TopicId="33" TopicName="Coverage3" />
            </content:Topics>
        </ContentItem>
    </CatalogItem>
    </CatalogItems>
</content>
protected void Page_Load(object sender, EventArgs e)
        {
            LoadXML();
        }

        public void LoadXML()
        {
               
            XmlDocument doc = new XmlDocument();
            doc.Load("PATH TO XML HERE");
            XmlNodeList elemList = doc.GetElementsByTagName("content:Topic");

                for (int i = 0; i < elemList.Count; i++)
                {
                    string x = elemList[i].Attributes["TopicName"].Value.ToString();

                    DropDownList1.Items.Add(new ListItem(x, x));
                }  


        }
