I'm trying to get the value from a table (I have no control over this format or naming) and I'd like to grab the value of "Opened Account" in the example below but not sure how to go about it? I'm trying to target "th.rich-table-headercell" but not sure how to grab value?

<table class="rich-table home table" id="startForm:OpenedReviewApps" border="1" cellpadding="0" cellspacing="0">
     <colgroup span="0"></colgroup>
     <thead class="rich-table-thead">
         <tr class="rich-table-header">
             <th class="rich-table-headercell" scope="colgroup">Opened Accounts
             </th>
         </tr>
    </thead>
   <tbody id="startForm:OpenedReviewApps:tb">
        <tr class="rich-table-row rich-table-firstrow">
            <td class="rich-table-cell" id="startForm:Open" style="width:80%"> some data here
            </td>
        </tr> 
    </tbody> 
</table>

you can try use document.getElementById, like:
<script language="javascript">
    var v = document.getElementById("startForm:Open").innerText;
    alert("Your var = " + v);
</script>

Hi Ryan,
there is no "id" on the "th" I'm trying to read:

<th class="rich-table-headercell" scope="colgroup">Opened Accounts</th>

Thanks

ooops, miss understood your question, perhaps you can try this instead:

<script language="javascript">
    var ths = document.getElementsByTagName("th");
    for (var i = 0; i < ths.length; i++) {
        if ((ths[i].getAttribute("class") == "rich-table-headercell") && (ths[i].getAttribute("scope") == "colgroup")) {
            var v = ths[i].innerText;
            break;
        }
    }
    alert("Your var = " + v);
</script>
