I am very new to web development and was wondering if there is any useful library that will allow some type of markup to be displayed created by users similar to stackoverflow. Specifically I am asking the user the post code and want them to be able to format it.

It is actually quite simple as long as you force users to type tags as well.
If you force user to type something like this to your input form:
<b>This is bold</b> and this is not.
and use the following code:
var text = $("#input-text").val();
$("#output-element").html(text);
Then tag will be formatted as html tag and you will see bold text instead of < b > in the output element. This works for all the possible tags as well.

I am working on a HTML parser which receives a input from user and produce HTML document in tag. Now to avoid XSS attacks I need a simple HTML sanitizing script which filter out all java-script elements and allow only HTML component.
There is not way you can properly sanitize user input on client side, because it can all be bypassed, users can simply remove event handlers, delete javascripts. the only way to properly sanitize user input is with client-side programming language.

I want to teach a basic programming (conditional statements,loop statements..) to secondary schools. I want to teach them using some games,where left side code exists and right side the output displays.Whenever user edits the left side code and press submit, right side output will be displayed.
I want something like in w3schools or jsfiddle.
Suggest something how to do it.
Is there any embedable editors like this or is there any API where we forward our code on button click and take the output and display it in frame.Is there any open-source project like this,so i can fork it and modify according to my reqs.
I want to develop this in meteor.
Disclaimer: I don't know anything about meteor
But if it's a JS library...
http://repl.it/ has a javascript mode (a bit like your examples above) and perhaps you could just include the library as the first line of code?

I want to write a simple javascript code for a text area, which should spell check the words in the text area with custom word list (medical words). I have a word list with more than 5000 medical words and I want to use that as the custom list. After comparing with the custom list, if the spelling is wrong, it should provide suggestions from the custom list, so that you can correct in the text area.
Are there any javascripts out there for this? I tried BJspell, but there is no option to add custom words.

I am creating an angular-js based web application. I want to create an automated walkthrough/app-tour for the same - just like we see on google or facebook when they release some new features/buttons.
This is to ask the community if they can direct me to some tutorials. Also, I would like to create text boxes pointing at my features, say some button in the app. How do I make sure that this text box is positioned at the same place as the button?
You can use IntroJS library which is simple, easy to use and free. Check the site, click the green button 'Show me how' to get an intro to intro!

Is there any open source online WYSIWYG Editor for various XML documents? I think the style could be added by XSLT, but if there is an editor, wich uses some other way to assign style to an XML file, I'm intrested.
EDIT: I've checked Xopus, Jaxe, Vex, Oxygen, Bitflux already, but none of them are matches the conditions above (not opensource, not online, etc)
WebJaxe is the online equivalent of Jaxe. It's actually more than that, since it has CMS features. As with Jaxe, you can change the look of XML elements in the editor with a config file. WebJaxe can use a PHP script and an XSLT transform to generate a website with the XML.
