String to HTMLdocument

String to HtmlDocument

The HtmlDocument class is a wrapper around the native IHtmlDocument2 COM interface.

You cannot easily create it from a string.

You should use the HTML Agility Pack.

Getting HtmlDocument from string without using browser control

You can use HtmlAgilityPack .... For example:

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);

var results = doc.DocumentNode
    .Descendants("div")
    .Select(n => n.InnerText);

Converting a string to an HTML document

The reason is because you declared ahtm as Nothing. instantiate it and see if it works.

Update:
HtmlDocument is a wrapper around an unmanaged class (IHtmlDocument). Try Declaring a WebBrower and then assigning the ahtm to the web browser document property.

WebBrowser wb = new WebBrowser();
HtmlDocument atm = wb.Document;

In other words, Web browser is the easiest way.

Update:
The alternative would be to use something like HtmlAgilityPack. http://htmlagilitypack.codeplex.com/

How to convert raw html (string) to htmlDocument in Java

Checking source code of HTMLDocument gives you the answer.

It have a cool constructor to take html string.

public HTMLDocument(final String data) {
        Charset cs = Charset.forName("utf-8");
        this.data = data.getBytes(cs);
        this.charset = cs;
    }

So

HTMLDocument doc = new HTMLDocument(htmlStr);

C# Convert HtmlString into HTMLDocument

I think this StackOverflow discussion will help you.
You can find two ways to solve your problem:

• with HTML Agility Pack
• with the following code :

---

  HTMLDocument doc = new HTMLDocument();
  IHTMLDocument2 doc2 = (IHTMLDocument2)doc;    

  doc2.write(fileText);

Creating an HTMLDocument from a String of HTML (in Java)

Try to use HtmlEditorKit class. It supports parsing of HTML content that can be read directly from String (e.g. through StringReader). There seems to be an article about how to do this.

Edit: To give an example, basically I think it could be done like this (aftrer the code is executed, htmlDoc should contain the loaded document...):

Reader stringReader = new StringReader(string);
HTMLEditorKit htmlKit = new HTMLEditorKit();
HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument();
HTMLEditorKit.Parser parser = new ParserDelegator();
parser.parse(stringReader, htmlDoc.getReader(0), true);

Sub Forex(currency1 As String, currency2 As String)

    Dim url As String, html As String, id As String
    Dim oResult As Variant, oLine As Variant, sRate As String

    url = "http://finance.yahoo.com/q?s=" & currency1 & currency2 & "=X"
    id = "<span id=""yfs_l10_" & currency1 & currency2 & "=x"">"
    html = GetHTTPResult(url)

    oResult = Split(html, vbLf)
    For Each oLine In oResult
        If InStr(1, oLine, id, vbTextCompare) Then
            sRate = Split(Split(oLine, "<span id=""yfs_l10_audusd=x"">")(1), "</span>")(0)
            Exit For
        End If
    Next
End Sub

Function GetHTTPResult(sURL As String) As String
    Dim XMLHTTP As Variant, sResult As String

    Set XMLHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
    XMLHTTP.Open "GET", sURL, False
    XMLHTTP.send
    sResult = XMLHTTP.responseText
    Set XMLHTTP = Nothing
    GetHTTPResult = sResult
End Function
