is there a way to alter the rendered HTML page in webbrowser control? What i need is to alter the rendered HTML Page in my webbrowser control to highlight selected text.
What i did is use a webclient and use the webclient.Downloadstring() to get the source code of the page, Highlight specific text then write it again in webbrowser. problm is, images along with that page does not appear since they are rendered as relative path.
Is there a way to solve this problem? Is there a way to detect images in a webbrowser control?
Not sure why you need to change the HTML to lighlight text, why not use IHighlightRenderingServices?
To specify a base url when loading HTML string you need to use the document's IPersistMoniker interface and specify a url in your IMoniker implementation.
I suggest you do it a different way, download and replace the text using the webbrowser control, this way your links will work. All you do is replace whatever is in the Search TextBox with the following, say the search term is "hello", then you replace all occurances of hello with the following:
<font color="yellow">hello</font>
Of course, this HTML can be replaced with the SPAN tag (which is an inline version of the DIV tag, so your lines wont break using SPAN, but will using DIV). But in either case, both these tags have a style attribute, where you can use CSS to change its color or a zillion other properties that are CSS compatible, like follows:
<SPAN style="background-color: yellow;">hello</SPAN>
Of course, there are a zillion other ways to change color using HTML, feel free to search the web for more if you want.
Now, you can use the .Replace() function in dotnet to do this (replace the searched text), it's very easy. So, you can Get the Whole document as a string using .DocumentText, and once all occurances are replaced (using .Replace()), you can set it back to .DocumentText (so, you're using .DocumentText to get the original string, and setting .DocumentText with the replaced string). Of course, you probably don't want to do this to items inside the actual HTML, so you can just loop through all the elements on the page by doing a For Each loop over all elements like below:
For Each someElement as HTMLElement in WebBrowser1.Document.All
And each element will have a .InnerText/.InnerHTML and .OuterText/.OuterHTML that you can Get (read from) and Set (overwrite with replaced text).
Of course, for your needs, you'd probably just want to be replacing and overwriting the .InnerText and/or the .OuterText.
If you need more help, let me know. In either case, i'd like to know how it worked out for you anyway, or if there is anything more any of us can do to add value to your problem. Cheers.

I am using vue2-editor and i want to toggle the content view of the editor like ckeditor or mailchimp editor does
It is possible using vue2-editor or quill?
You can have a computed property that either returns the actual text or uses a library like hypertext to generate html, the return value of the html would be contingent on another computed property and returns the html you want.
I also have a simpler solution, which I used once but need to take a look at my code in a few hours which is not in front of me.
I would like JS <script type="xx"> content to be colored nicely inside my HTML document.
Right now, when adding the type to a script tag, the element text becomes uniform white, as seen below.
Of course, the JS code is colored nicely within the HTML if removing the type attribute.
Is there some setting I can modify to make this work?
No setting to modify. This is a known issue. From the thread it looks like syntax highlighting was working at one point for script tags with the type attribute but was lost.
Hopefully it's fixed soon. I'm seeing the same thing on VSCode 1.13.1.
Is it possible to pass an HTML node into labels? I specifically was looking to make the label also a hyperlink - e.g. Label. I also saw someone asked about Chartist label as image, which this would also resolve.
I tired populating the labels array w/ HTML and with dom nodes (createElement). I also tried passing dom nodes and string containing HTML through labelInterpolationFnc without luck.
Is there any way to accomplish this?
I generate html documents that contain a menu and a content part. Then I want to extract the content of these document to feed it to a lucene index. However, I would like to exclude the menu from the content extraction and thus only index the content.
<div class="menu">my menu goes here</div>
<div class="content">my content goes here</div>
what is the simplest way to achieve this with apache tika?
As a more general solution (not just for you specific menu) I would advise looking at boilerpipe that deals with removing uninteresting parts from pages (menus, navigation etc).
I know it can be integrated in Solr/tika, have a look and you probably can integrate it in your scenario.
Have a look at this post which specifies how to handle DIVs during the HTML parse, by specifying whether they are safe to parse or not, in which case its ignored. For your problem, you could have some logic in the override methods which ignore only DIV elements with attribute value "menu" (i.e. tell TIKA parser this DIV is unsafe to parse).
You can parse the html with a parser to a xhtml dom object an remove the div tag cotaining the attribute class="menu".
I need to have some hidden text in HTML to parse as text when i read an actual HTML file
I used to include my text in hidden div using style but i knew that may record us as spammers in SEO
.hideme {
position : absolute;
left : -1000px;
}
Can i have this content as commented text in the HTML ?
will that be safe as i know that SEO crawlers ignores the comments in HTML
<!-- my hidden text -->
Please advice
The search engines only care about hidden text when it is used to manipulate a page's rankings. Typically this is defined as content that is presented to the search engines that is not presented to users. So if you hide text so users can't see it but crawlers can you will find yourself having issues with Google. An example of when hiding text is good is when you use display:none to hide dynamic content and then use JavaScript or CSS to display the content when an action is performed (i.e. mouseover, etc).
If you place this extra content within comments as you suggest in your question you will be fine as this content is not available to users and search engines ignore comments.
Try to avoid "hide" in naming your CSS class.
But the best way is to avoid hidden text by finding easy and creative ways to add the text to the content of a web-page without seeming like spam.
You can't parse html comments so instead use a hidden field:
<input type="hidden" value="my text" name="my_hidden_field/>
Some people for SEO doing this :
.hideme {
width:0px;
overflow:hidden;
text-indent:-99999px
}
Why you do not use <meta> tags ?
