Screen scrap web page that displays data page wise using Mechanize
===

I am trying to screen scrap a web page (using Mechanize) which displays the records in a grid page wise. I am able to read the values displayed in the first page but now need to navigate to the next page to read appropriate values.

    <tr>
        <td><span>1</span></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$2')">2</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$3')" >3</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$4')" >4</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$5')" >5</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$6')">6</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$7')" >7</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$8')">8</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$9')" >9</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$10')" >10</a></td>
        <td><a href="javascript:__doPostBack('gvw_offices','Page$11')">...</a></td>
    </tr>

I am able to get through all the links but when I try this:-

    links = (row/"a")
    links.each do |link|
    	agent.click link.attributes['href']   # This fails 
        agent.click link   # This also fails
    end


Reason is that agent.click expects the URL as an argument.

Is there a way where we can read all the values when they are displayed page wise ? If not how can we have such a click action when the href is a postback and not a URL??
