XMLDocument Load

I currently have the function below which I use for pulling data out of an XML file. I use this many times around the site.

The problem is, the XML document rarely changes, but the system has to load it all in every time it wants to use it.

Is there any way of creating a global XML document that is only read in once and just referenced with this function instead?

Dim oContent As New XmlDocument
        oContent.Load(HttpContext.Current.Server.MapPath("/includes/content/content.xml"))
        Try
            Return oContent.SelectSingleNode("/xml/Contents/Content[attribute::title='" & sTitle.ToLower & "']").InnerText.Replace("&lt;", "<").Replace("&gt;", ">")
        Catch ex As Exception
            Return ""
        End Try
        oContent = Nothing

Thanks

Re: XMLDocument Load

You can make use of Cache object . Read the xml file from global.asax ( on Application_Start event) and cache it.

Is there any problem using a session instead?

I guess I lied a bit when I said it's not updated regularly - it could potentially be updated every evening.

Thanks

Re: XMLDocument Load

Hi,

There is difference between the Cache and session.

The Cache is open to all the users in the application. the session is open to the specific users.

If you store the xmldocument into session, it only be retrieved by the one user.

You should store it for every user.

And in the Cache , you only store once, you can get it in any place.
