    Exclamation Get the data of Anchor tag.

    Hello there,

    I have added WebBrowser component on my form. It loads my own website on webbrowser.navigate(). Then I login in and navigate to my private page.

    Now, I want to grab some data between anchor tag. There are multiple anchor tags in that page. Like,

    HTML Code:
    <a href="something" class-index="something" id="something"> My Data </a>
    <a href="something" class-index="something" id="something"> My Data 2</a>
    <a href="something" class-index="something" id="something"> My Data 3</a>
    I want to loop through get these values "My Data","My Data 2","My Data 3" ... and so on..

    How can I do this ?

    Thanks!

    Re: Get the data of Anchor tag.

    Use the InnerText property to obtain content values from anchor tags.

    VB.NET Code:
    1. Dim myData As New List(Of String)
    2. Dim anchorCollection As HtmlElementCollection
    3. anchorCollection = WebBrowser1.Document.GetElementsByTagName("a")
    4. If (Not anchorCollection Is Nothing And anchorCollection.Count > 0) Then
    5.     For Each element As HtmlElement In anchorCollection
    6.         myData.Add(element.InnerText)
    7.     Next
    8. End If

    Thanks for your reply! The problem with this is that it is fetching all data with Anchor tag. I have specified some attributes to the Anchor tage like,

    <a href="something" data-hovercard="something" data-gt="">My data</a>

    Is it possible to detect data-hovercard or data-gt and only return those data having this tag ?

    Anyway again thanks

    Yes, just add condition to get the attribute value of a specific tag.
    VB.NET Code:
    1. For Each element As HtmlElement In anchorCollection
    2.       If element.GetAttribute("data-hovercard").Equals("something") Then
    3.                     myData.Add(element.InnerText)
    4.       End If
    5. Next

    Actually, I cannot pretend the value of "data-hovercard" because it's dynamic. Just want to check if it is there. And if it exists then show the inner value.

    Just revise the If condition to check whether data-hovercard has a value or empty. If it has value, then add it to myData list object.
