Hi Kamna,
We are trying to figure out how to validate the form field values in XWiki.

> </form>

You can use stuff such as #if ($request.name !="" && $request.email !="" )
do action #else $msg.error #end

> <input type="text" name="email" value="xyz">
> <textarea name="feed"></textarea>
> <input type="submit" value="Submit" />
> # set($name = $request.getParameter("name"))
> # set($email= $request.getParameter("email"))
> # set($feed= $request.getParameter("feed"))
> </form>

That's because XWiki recognizes
# hello
# world
as a numbered list and it will render
1. hello
2. world
You need to write
#set($a = $b)
instead of
# set($a = $b)
-> there's one space too many on your line ;-)
