How to insert text into a file using web input forms?
<p>I have a simple text file that needs to be updated on a regular basis.  Instead of cutting and pasting the new data, I'd like to have a web input form where I can just enter the new info, and it will update the text file.  For example, I may enter a new "Headline", or "URL", and I'd want that string to be inserted into the correct place in the file. </p>

<p>What's the easiest way for me to do this?  The file doesn't have to be saved, I can copy and paste the text file after it generates the new text. </p>

<h2>For example, the text that I would want updated looks like this:</h2>

<p>[Headline] </p>

<h2>the above sentence is the headline and this is the [URL]</h2>

<p>There would be 2 web input forms.  1 for Headline, 1 for URL.   When I enter text into the input, the javascript would insert it into the correct place in the textarea.  Then I can just copy and paste that text into whatever I needed.  This is a very simple script, I just have no idea how to build it.</p>
