Hi All,

I’m having a text area in my rails application as \<%= f.text\_area :text  
%\>. User allowed to enter HTML tags in that text area. I’m facing  
following problems:

1. Not able to check whether the HTML tags entered by user are correct  
or not i.e how to check whether the HTML tags are properly closed or not  
(\<\>).

2. If the user copies the source code of any site and pastes it into  
above text field, the layout distracts.

Suggestions Appreciated…

Thanks and Regards

Saurabh P.
