    Get values

    Hello,

    I am trying to load information from a XML file using only the nodes
    which attribute footer=true.

    I created the following code:

    Dim siteMap As New System.Xml.XmlD ocument
    siteMap.Load(Ht tpContext.Curre nt.Server.MapPa th(Me.SiteMapUr l))
    Dim siteMapNodeList As XmlNodeList =
    siteMap.SelectN odes("sitemapno de[@footer='true']")
    Dim iSiteMapNode As Integer

    ' Loop through each node in XML node list
    For iSiteMapNode = 0 To siteMapNodeList .Count - 1

    ' Create new hyperlink
    Dim link As New HyperLink

    ' Define hyperlink properties
    With link
    .ID = "by27f_h" &
    siteMapNodeList (iSiteMapNode). Attributes("tit le").Value
    .NavigateUrl =
    siteMapNodeList (iSiteMapNode). Attributes("url ").Value
    .Text =
    siteMapNodeList (iSiteMapNode). Attributes("tit le").Value
    .ToolTip =
    siteMapNodeList (iSiteMapNode). Attributes("tit le").Value
    End With

    Next

    I am not getting anything.

    My XML file is as follows:

    <?xml version="1.0" encoding="utf-8" ?>
    <siteMap
    xmlns = "http://schemas.microso ft.com/ASPNet/SiteMap-File-1.0" >
    <siteMapNode>
    <siteMapNode
    url = "~/Default.ASPx"
    title = "Home"
    description = "Desc1"
    footer = "true" />
    <siteMapNode
    url = "~/Contacts.ASPx"
    title = "Contactos"
    description = "Desc2"
    footer = "true" />
    </siteMapNode>
    </siteMap>

    Could you tell me what am I doing wrong?

    I can't understand why I don't get any values.

    Thanks,
    Miguel

      Re: Get values

      Try using a System.Xml.XPat h.XPathNavigato r to navigate your XmlDocument, by
      using the CreateNavigator method:

      http://msdn2.microsoft.com/en-us/lib...navigator.aspx

      The XPathNavigator class allows you to navigate in all directions in an
      XmlDocument, using XPath expressions:

      So I bit him.
