Hi,

I am trying to sort a repeating table with the help of JScript. I found
an example in an demoform that came with Infopath.

I am using this code, but I could not figure out what the function
expects as fnCompare.
Can anyone shed some light please? I always get an error at this line
rgItems.sort(fnCompare);

Thanks in advance, Martin

function sort(xpathParent, xpathChildren, fnCompare)
{
    // Retrieve the parent node; all the children will be sorted.
    var xmlOrigParent = getNode(xpathParent)
    var xmlItems = xmlOrigParent.selectNodes(xpathChildren);

    if (1 < count(xmlItems))
    {
        // Store the (pointers to) items in an array for faster access.
        rgItems = new Array();

        while (xmlItem = xmlItems.nextNode())
            rgItems.push(xmlItem);

        // Sort the array (the XML does not change).
------->        rgItems.sort(fnCompare);

        // Now that the array is sorted the DOM should be updated.
        var xmlSortParent = xmlOrigParent.cloneNode(true);
        var xmlClones = xmlSortParent.selectNodes(xpathChildren);
        xmlClones.removeAll();

        // Update the nodelist, each item is moved only once.
        // (each change is causing several notifications to be fired.)
        for (var i=0; i<rgItems.length; i++)
            xmlSortParent.appendChild(rgItems[i].cloneNode(true));

        xmlOrigParent.parentNode.replaceChild(xmlSortParent, xmlOrigParent);
    }
}
