VS 2008 : Check If HTML Element Exists?

Sep 8, 2010

How do I check if an HTML element exists? This element will only "show" on a certain event. ex: numbers in a non-number textbox or something. I tried

If WebBrowser1.Document.GetElementsByName("ElementName")

But that won't work, because the element "is in" the HTML, even though the page doesn't show it yet.

VS 2010 Check For Element Or Keep Trying Until Element Is Found?

Feb 21, 2012

I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes

I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE

So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is

Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then
WebBrowser1.Navigate(emailver.InnerText)

[Code]...

HTML Parsing - Check If Element Has Specific Attribute?

Dec 25, 2010

I'm using HtmlAgilityPack to parse HTML. I want to check if an element has a specific attribute. I want to check whether an <a> tag has the href attribute.

Dim doc As HtmlDocument = New HtmlDocument()
doc.Load(New StringReader(content))
Dim root As HtmlNode = doc.DocumentNode
Dim anchorTags As New List(Of String)
For Each link As HtmlNode In root.SelectNodes("//a")
If link.HasAttributes("href") Then doSomething() 'this doesn't work because hasAttributes only checks whether an element has attributes or not

Asp.net - Element 'system.webServer' Has Invalid Child Element 'rewrite'?

Feb 14, 2012

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Jun 7, 2011

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example

Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

Read HTML Element In .NET 2008?

Feb 11, 2009

I'm trying to read an innerHTML string from an element on a webpage. I've loaded the page using the webbrowser browser class.

Here's the code in full

Imports System.Net
Imports System.IO
Imports System.Diagnostics

[Code]...

When I click button 1 for the first time I recieve the error "Object reference not set to an instance of an object." but when I click it the second time it returns the elements text perfectly.

I thought the wb.document element might not be instantiated so I've tried navigating to a page (google's homepage) before loading the page I want put with no success.

I also thought that maybe it wasn't giving the page time to load so I added the sub to deal with the documentCompleted event but this also returns nothing (though wb.document.url is set correctly to the webpage I want)

VS 2008 How To Parse Every Element In XmlReader

Jun 2, 2011

I have the following code that adds the elements from between the <movie></movie> elements to a listview box.Private Sub ParseMovie(ByVal reader As XmlReader)

[Code]...

What I would like to do is make sure that it reads everything instead of using ReadToFollowing. I might add something else to the xml file, such as <release_date></release_date> and I want to make sure I don't have to edit the ParseMovie sub routine. I looked at the members of XmlReader, but I can't seem to get the right methods to do this efficiently. How should I parse every element between <movie></movie>.
