Sooooo close. Thank you, but instead of habing individual items that you can choose from in the Combobox, it slaps all items into 1

So I scarpped the whole thing and replaced it with this:

Public Function FillFeedList(combo As ComboBox, category As String)
        'Connect to Internal Feed Database
        Dim path As String = "RSSFeeds.xml"
        Dim feedDoc As New XmlDocument()
        feedDoc.Load(path)

        Dim selectedCategory As XmlNodeList = feedDoc.SelectNodes("category/" + category)
        Dim i As Integer = 0
        For Each node In selectedCategory.Item(i)
            Dim feedLink As XmlNode = selectedCategory.Item(i).SelectSingleNode("link")
            If feedLink IsNot Nothing Then
                'combo.Items.Add(feedLink.InnerText)
                combo.DataSource = (From element In feedLink Select element.Value).ToList()
            Else
                combo.Text = Nothing
            End If
        Next

        i += 1
        Return Nothing


    End Function

the only problem, is it still only loads one feed, the first one.
I copied a bunch of links into the eq feed like this:

<?xml version="1.0"?>

Nope. Again, no errors but its preventing my DataGridView from filling

Ok, So I reverted back to your original. The error for XmlDocument.Load("myfile.xml") is "Referrence to a non-shared member requires an object referrence"

My RSS Feed XML

Ok, it fixed that, but now its just not working, no errors. I had to slightly odify the code because Document Element wasnt workin, so i switched it to Elements

Public Function GetFeeds(ByVal FeedsDoc As XDocument, ByVal category As String) As String()

If (FeedsDoc Is Nothing) Then
Throw New ArgumentNullException(NameOf(FeedsDoc))
End If

Dim node As XmlElement = CType(FeedsDoc.Elements("/category/" + category + "/link"), XmlElement)

If (node IsNot Nothing) Then
Return node.InnerText.Split(New String() {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
Else
Return New String() {}
End If

End Function


Only issue I am having is that XmlDocument doesnt have a .Load function

Thats all I want to do. Basically I have a Combo box and a DataviewGrid. My RSSParser class takes care of translating known RSS feeds and listing the items in the DataViewGrid, All i want to do, is be able to select with the combo box, which feed I want to populate the GridView with.

But I also want the user to be able to customize which Feeds are available, hence the textfile with categories and feed links

I have no problems with my XML streamer, its the text file streaming. Im not sure how to find a chunck of text, in this case: a chunck between <category1> and <_/category1>

Would it be easier to write and read to an xml rather than a text file?
