I nedd to do a little variation of this code to make it works in WPF, here is the code:

1- I need to add the reference: Microsoft.mshtml (solution explorer / Referenes)

2- add using mshtml;

3- code for the event LoadCompleted (wbContenido = WebBrowser control)

private void wbContenido_LoadCompleted(object sender, NavigationEventArgs e)
{
mshtml.HTMLDocumentClass dom = (mshtml.HTMLDocumentClass)wbContenido.Document;
//Console.Write(dom.body.innerHTML);

IHTMLDocument2 doc2 = dom;// wbContenido.Document.DomDocument as IHTMLDocument2;
StringBuilder html = new StringBuilder(doc2.body.outerHTML);

var words = new[] { “Examen”, “passione” };
foreach (String key in words)
{
String substitution = “” + key + “”;
html.Replace(key, substitution);
}

doc2.body.innerHTML = html.ToString();
}

“This is a HighLight Me please sample”.

My search word is “This is a HighLight Me please sample” and this should match the above exampe and ignoring the html element.

A better solution I found, as I said before, was switching to an alreaady tested javascript function to hilite text.

To reverse hiliting the best way is to save the original content of the page, and when you need to remove hilighting you simply reassign old content to the innerHTML property.

alk.

mshtml.HTMLDocument doc2 = (mshtml.HTMLDocument)RealBrowser.Document.DomDocument;
StringBuilder html = new StringBuilder(doc2.body.outerHTML);

foreach (String key in words)
{
String substitution = “” + key + “”;
html.Replace(key, substitution);

doc2.body.innerHTML = html.ToString();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

i use this and when i click on the highlighted HTML link it is not working

this is the code for the button

private void button8_Click(object sender, EventArgs e)
{
//if containts >1 word
if(searchKeywords.Length > 0)
{
//reverse the highlighted keywords if it only worked!!
foreach(string keyword in searchKeywords)
{
var temp_str = “” + keyword + “”;
webBrowser1.DocumentText = webBrowser1.DocumentText.Replace(temp_str, keyword);
}
webBrowser1.Invalidate();
}
//the textbox may have many word divided by char space
var keywords = textBox2.Text.Split(‘ ‘);
//grab the values for use to reverse highlighting
searchKeywords = keywords;

//highlight search keywords in webbroswer control
foreach (string keyw in keywords)
{
//MessageBox.Show(index.ToString());
webBrowser1.DocumentText = webBrowser1.DocumentText.Replace(keyw, @”"+keyw+”");
}
//control repaint
webBrowser1.Invalidate();

}

but the reversing of highlighting doesn’t work . what do you think?

string substitution = + text.ToString() + ;

My program haven’t run the code in documentcompleted eventhandler

when it step to the first statement (HtmlDocument abc = (HtmlDocument)webBrowser1.Document.DomDocument;
), it step out

Can you tell me which part i have caused the problem?

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
HtmlDocument abc = (HtmlDocument)webBrowser1.Document.DomDocument;
StringBuilder html = new StringBuilder(abc.Body.OuterHtml);

string text = \school\;

string substitution = \\ + text.ToString() + \\;

html.Replace(text.ToString(), substitution);

abc.Body.InnerHtml = html.ToString();
}
