[OpenLayers-Users] Query Feature by Attribute and Zoom

Hello,

I am fairly new to OpenLayers and GIS in general and new to this list.  I
have just setup an OpenLayers page.  I am using MapServer as my WMS Server
and my data is held in PostGIS tables. 

I would like to know how can I create a way for a user to input text and to
zoom to the feature specified by the text.  

An example of what I am trying to accomplish:  
Take the Feature Info Example at
http://www.openlayers.org/dev/examples/getfeatureinfo.html.  If I wanted to
make it so a user could type in a country name then have the map zoom to the
extent of the country, how would I do so?  It needs to be a general enough
example I could use it with any text field (for example, a Serial Number).  

I have found a few previous postings that seem to be asking a similar
question but not many answers.  Any pointers to a nice or ugly solution are
appreciated.

Thanks.

Greg
