filter extracted link from webpage using htmlagility - vb.net

Question

Problem one:

I have a program for extracting urls of a webpage ( WebSource ) with a specific content ( /articles/ )

Dim links As New List(Of String)()
Dim htmlDoc As New HtmlAgilityPack.HtmlDocument()
htmlDoc.LoadHtml(WebSource)
For Each link As HtmlNode In htmlDoc.DocumentNode.SelectNodes("//a[@href]")
    Dim att As HtmlAttribute = link.Attributes("href")
    If att.Value.Contains("/articles/") Then
        links.Add(att.Value)
    End If
Next

Is it possible to search in urls and filter them by two value, for example in a tech site i want find all urls contain /articles/ and LG

Problem two:

Extracted urls are not complete HTTP address for example one of my results is

/articles/car

Instead of complete address for example

http://website.com/articles/car

How can i fix this?

Answer 1

you are checking ONE content now . for checking multiple items in htmlagility you can use multiple if statement as follow

If att.Value.Contains("content1") Then
    If att.Value.Contains("content2") Then
        If att.Value.Contains("content3") Then
            links.Add(att.Value)
        End If
    End If
End If
