It is possible to load a html page(online one) in webBrowser BUT, Before loading it into webBrowser, to load it into a string, clean some tags there, and Then loading that string into webBrowser ?
Or any other variant?
I want to load certain tags from a web page into my webBrowser, and NOT the whole original page.(for example only a list, or only the images- from a specific page)
Can be done?
I suppose it must be done with the help of php, but i dont know it.
Thanks, once again.

For example:
If I have to load this page: http://translate.google.co.uk/?hl=en&tab=TT
I want to be able to get rid of the " <<pre>div id="gb">" INSIDE that page. (That div is the top menu from that page).

Solution 3

You may do this in two steps.

1) Read content from HTML file. -

Either you can read content of your HTML file using WebClient().

C#

client = new WebClient();
String htmlString = client.DownloadString("MyFile.htm");

Or using StreamReader.

C#

String htmlString = String.Emtpy;
using( StreamReader reader = new StreamReader( @"MyHtmlFilePath" ) )
{
   htmlString = reader.ReadToEnd(); 
}

2) Then modify your htmlString and assign it to WebBrowser Control using DocumentText Property. Have a look at below link for more information on this.

I also found below link interesting.

Update - Since you updated your Question.

Why you need PHP for this? You can modify/manupulate your HTML sting using simple StringBuilder or using "Html Agility Pack".

see the example I updated the page.

RaisKazi 26-Nov-11 11:26am

Ok so whats the problem. You may exclude it from your HTML string using "Html Agility Pack" or "Regular Expression".

_Q12_ 26-Nov-11 11:40am

OK, I'll look over the "Html Agility Pack", But I never worked with it... I hope is free and not too complicated, and most of all to do what i need to do...
If I encounter problems, can I discuss them further with you here?
I then give you a big +5 stars if anything looks good. ;)

RaisKazi 26-Nov-11 12:10pm

Sure. But I would have gone with "Regular Expressions" for this as a deal is to only exclude one div tag. I may not be available too long as its my Bed-Time :). But you may post your difficulties as a separate Question and I am sure some one will provide you solution. Will wait for that big +5 stars :).

_Q12_ 26-Nov-11 12:38pm

Im not so advanced in programming ... so I think I cant load a web page in my webBrowser after all with this class... I managed to reference its dll, I write the first class from it:
HtmlAgilityPack.HtmlDocument hhh = new HtmlAgilityPack.HtmlDocument();
hhh.Load(html);
But its awfully complicated and way over my head.
So I must stick with using System resources for now...
Thanks for your support anyway.

LanFanNinja 26-Nov-11 13:09pm

Parsing HTML like this whether your using a library or writing all the code yourself can get very hard and aggravating. This line in your comment "But its awfully complicated and way over my head" suggest to me that you may not have the needed skill necessary to accomplish this task just yet. If you feel that I am wrong and you are ready for this project then by all means continue on! Just remember it is not the end of the world if you fail (or is it? :) ) I have seen lots of novice programmers try to tackle project beyond there skill level one time too many and give up on programming all together! Don't let this happen to you. Good luck.

P.S. In your example finding the div "<div id=gb>" is the easy part. Its in finding the matching end tag "</div>" where things can get confusing.

_Q12_ 26-Nov-11 16:41pm

LanFanNinja____ response:
Thanks and I don't want to give up...yet. It's a lot of fun until now. :)

I just want to find a way (from many possible) to accomplish this task on retrieving live stream of a web page, clean it up, then render inside webBrouser1.
(this is the BEST explanation of my intent!)
---
The string manipulation(retrieve,erase,replace,etc)...is not easy, but i can face it.It's not easy because at every string (long ones-especially from files_until now) I encounter a little "something" that required some days of work. Here I give just an example...In reality, I have to deal with some javascript codes embedded in pages, css and other malformations of html.

_Q12_ 26-Nov-11 17:01pm

Can you make me a demo code with HtmlAgilityPack, in retrieving a live stream from a web page and the rendering part inside webBrowser ? Because I cant find squat there. Its very abstract and I cant find examples on how to do it.
Thanks.

RaisKazi 26-Nov-11 22:18pm

We can provide you references, you will have to learn and then use them. I found one more useful article here on CodeProject it self.

Convert HTML to XHTML and Clean Unnecessary Tags and Attributes

I think alongwith programming you should learn Art of "Search" on Google/MSDN/CodeProject etc. Which is going to help you in future.

Thank you SA.

_Q12_ 27-Nov-11 6:25am

Your link is not helping me. That code is for cleaning htmls pages. I already specify that the cleaning is my job. Right now I need the code who can load a html page but not consume it, it will store it into a buffer as a stream or something, (I will do the cleaning of that page), then something will take the cleaned code and render it in webBrowser. Thats it.
thanks.

RaisKazi 27-Nov-11 7:56am

My answer has two steps. First step provides you a way by which you can download HTML content into string. Second step and my earlier comments has many ways by which you can modif that string HTML and then assign it to your WebBrowser control. I suggest you read my answer and comments once again, I hope it should be helpful.

Solution 2

Have you tried setting the DocumentText property?

WebBrowser1.DocumentText = "<html><head><title>Hi</title></head><body>Hello world!</body></html>";

Please read the content of the question first.

Yvan Rodrigues 26-Nov-11 11:35am

I did but you didn't say which part your having difficulty with. If the document that you are retrieving is valid XML you can load it into an XDocument or XmlDocument object and manipulate it there. Otherwise you're stuck manipulating it with regular expressions.

Sergey Alexandrovich Kryukov 26-Nov-11 21:14pm

Basically, you are right. This solution misses the first step (see the solution by Rais), but I also had an impression that OP had a problem with loading a document as HTML string. I voted 4.

Solution 1

You can load any HTML Page into the Your WebBrowser through code :

C#

System.Uri PagePath;
System.Uri.TryCreate("HTML File Path", UriKind.RelativeOrAbsolute,out PagePath);
WebBrowser1.Url = PagePath;
