Alternative For Each - In Loop ?

Below is the code for a linked list search I have tried to implement in to searching through each of the elements of htmlelements .For some reason If element.InnerText = (item) will only work if if is only a string ("example") .Are there any other ways of Implementing the for each loop to search through my item linked list?

Original code for searching for 1 string

Private Sub block()
Dim elements As HtmlElementCollection = webBrowser.document.All
Dim word_found As Boolean
word_found = False

[CODE]...

This is the Loop for item I have tried to implement but is not working ,because of the for each loop .The value of element.Innertext = "" or null when I try to use one of the linked list item[If element.InnerText = (item)] is used and only have a value when a string is used to [If element.InnerText = (google)]

Private Sub block()
Dim elements As HtmlElementCollection = webBrowser.document.All
Dim word_found As Boolean
word_found = False
Dim item As LinkedListItem = words.Head
