Hello Experts
I am trying to check a list of words and see if its available in the text (value)

Dim NonChangeable() As String = {"Daddy", "dad"}
Dim TagsToCheck() as String = {"<Father>","<Grandfather>","<GreatGrandFather>" }
Dim value As String = Trim(item.Value.Replace(Environment.NewLine, " \line "))

If text(i).Contains(TagsToCheck) Then
         If value.ToLower.Contains(NonChangeable) Then                            
             format(i) = "{0}"
          End If
End if

This is not working. Please can someone advice?

Thanks
M

Hi,

As far as I know

.Contains

 works with a string not an array of strings you should loop through them

Hi thanks for your input, is there any other way to use Contains without iterating in the loop?

I think I know what you are after but need a little more information.  What do the variables text, value and format contain?

Nevermind about value, what about item?

Well here is what I come up with:
Module Module1
	Private NonChangeable As String() = {"Daddy", "dad"}
	Private TagsToCheck As String() = {"<Father>", "<Grandfather>", "<GreatGrandFather>"}

	Sub Main()
		Dim text As String = "<Father>"
		Dim value As String = "daddy"
		Dim format As String = "I should change."

		Console.WriteLine(String.Format("Before linq: format = {0}", format))
		If Not String.IsNullOrEmpty((From tag As String In TagsToCheck Where text.Contains(tag) Select tag).FirstOrDefault()) Then
			If Not String.IsNullOrEmpty((From [static] As String In NonChangeable Where value.ToLower().Contains([static].ToLower()) Select [static]).FirstOrDefault()) Then
				format = "{0}"
			End If
		End If
		Console.WriteLine(String.Format("After linq: format = {0}", format))
		Console.ReadLine()
	End Sub
End Module

Open in new window


Produces the following output:Capture.JPG
And even though I have gussied it up with linq, it is, still looping.

However, this does beg the question, what is your ultimate goal.  This as it stands is a real cumbersome way to go about string replacement and formatting.

I have tried looping through the code earlier but then regardless of whether I need to perform this validation, its checking for every item, I need to only check if the
text(i)="<Daddy>" then I want to check its value if its "daddy" or "Daddy" , if found set to {0}

May be I need to do in some other way ....  I hope you understand what I am trying to ask?

 Dim iPatterns As New List(Of String)()
            iPatterns.Add("<Father>")
            iPatterns.Add("<grandmother>")
            iPatterns.Add("<grandmother's>")
            iPatterns.Add("<thegrandmother>")
            iPatterns.Add("<thegrandmother's>")

            Dim iPatternValue As New List(Of String)()
            iPatternValue.Add("daddy")
            iPatternValue.Add("granny")
            iPatternValue.Add("grandma")
            iPatternValue.Add("dad")



 For Each key As String In iPatterns
                            If text(i).ToLower.Contains(key) Then
                                For Each val As String In iPatternValue
                                    If value.ToLower.Contains(val) Then                                                               format(i) = "{0}"
                                    End If
                                Next
                            End If
                        Next

How about this:
Module Module1
	Sub Main()
		Dim iPatterns As New List(Of String)()
		iPatterns.Add("<Father>")
		iPatterns.Add("<grandmother>")
		iPatterns.Add("<grandmother's>")
		iPatterns.Add("<thegrandmother>")
		iPatterns.Add("<thegrandmother's>")

		Dim iPatternValue As New List(Of String)()
		iPatternValue.Add("daddy")
		iPatternValue.Add("granny")
		iPatternValue.Add("grandma")
		iPatternValue.Add("dad")

		Dim text As String = "<Father>"
		Dim value As String = "daddy"
		Dim format As String = "I should change."


		Console.WriteLine(String.Format("Before loop: format = {0}", format))
		For Each key As String In iPatterns
			If text.ToLower().Contains(key.ToLower()) Then
				For Each val As String In iPatternValue
					If value.ToLower().Contains(val.ToLower()) Then
						format = "{0}"
						Exit For
					End If
				Next
			End If
		Next
		Console.WriteLine(String.Format("After loop: format = {0}", format))
		Console.ReadLine()
	End Sub
End Module
