Subject: dynamic drop down menu based on xml data

I'm new to ruby, html and javascript (ouch).  In an erb file I am
reading a value from an xml.  Then I need to display a drop down menu
where THAT one is selected.  For now I am just hard coding all the
possible selections in html.

So for example see below, "animation_asset" may come back as being equal
to "Animation 2", in which case the html selection component would like
like below.

But how do I do this dynamically?  What if it comes back as "Animation
1".

I'm thinking I may need some javascript.  I have called hello-world
javascript through buttons, so I have some javascript functions in my
html doc already.  I'm just not sure what to call and what to return.
Thanks.

<%animation_asset = pathElementsArray[assetPos] # say it is equal to
"Animation 2"%>

<select name = "somename" value="">
  <option > Animation 1</option>
  <option selected="yes">Animation 2</option>
  <option>Animation 3</option>
</select>
