Find All Elements By Class (See related posts)

// Javascript function that will return an array of elements based on DOM element, tag, and class name.
// For instance, getElementsByClassName(document, 'tr', 'INFO') will get all "tr" tags under the document node with the "INFO" class and return an array of them.

function getElementsByClassName(oElm, strTagName, strClassName){
var arrElements = (strTagName == "*" && document.all)? document.all : oElm.getElementsByTagName(strTagName);
            var arrReturnElements = new Array();
            strClassName = strClassName.replace(/\-/g, "\\-");
            var oRegExp = new RegExp("(^|\\s)" + strClassName + "(\\s|$)");
            var oElement;
            for(var i=0; i<arrElements.length; i++){
                oElement = arrElements[i];
            return (arrReturnElements)
