I _just_ implemented a similar functionality to an AJAX based website for log viewing. I send the data to the client then do sorting (no filtering yet, but the OP has me inspired :) ) based on the data stored in local browser memory, rather than having to re-query the servers each time. Not very perlish, but here's what I did in case anyone is interested.

var logs = new Array();function ListLogs(response) {    theDoc.getElem
+entById('logResults').deleteTFoot();

    for (var i=0;i<response.getElementsByTagName('log').length;i++) {
        var members = response.getElementsByTagName('log')[i];
        var columns = new Array('time','passfail','protocol','status',
+'bytes','url');
        var values = new Array();
        for (var j=0;j<members.childNodes.length;j++) {
            var node = members.childNodes[j];
            for (var k=0;k<columns.length;k++) {                if (no
+de.nodeName == columns[k] && node.firstChild) {
                    values[columns[k]] = node.firstChild.nodeValue;
                }
            }
        }
        logs.push(values);
        addLog(values);
    }    resort('url');
}

var sortColumn = 'time';
function mysort(a,b) {
    if (a[sortColumn] > b[sortColumn]) return 1;
    if (a[sortColumn] < b[sortColumn]) return -1;
    if (a[sortColumn] == b[sortColumn]) return 0;
}
function resort(byfield) {    theDoc.getElementById('logResults').dele
+teTFoot();
    sortColumn = byfield;
    var tmp = logs.sort(mysort);
    for (var i=0;i<logs.length;i++) {
        var a = logs[i];
        addLog(a);
    }
}

The function addLog(rec) simply adds a row to the table of log entries.
