Привет ещё раз!!!  smile  smile 
Вот никак не могу полусить правельное значение элементов в XML файле...
Код

<?xml version="1.0" encoding="UTF-8" ?>
<activities>
    <montag></montag>
    <dienstag></dienstag>
    <mittwoch></mittwoch>
    <donnerstag></donnerstag>
    <freitag></freitag>
    <samstag></samstag>
    <sonntag></sonntag>
</activities>


а вот код который это дело считает
Код

<html>
    <head>
        <title>Activit&auml;ten f&uuml:r diese Woche</title>
        <script language="javascript" type="text/javascript" >
            var xmlHttp;
            var requestType = "";
            
            function createXMLHttpRequest(){
                if(window.ActiveXObject){
                    xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
                } else if(window.XMLHttpRequest){
                    xmlHttp = new XMLHttpRequest();
                }
            }
            
            function startRequest(requestName){
                requestType = requestName;
                createXMLHttpRequest();
                xmlHttp.onreadystatechange = handleStateChange;
                xmlHttp.open("GET","activities2.xml",true);
                xmlHttp.send(null);
            }
            
            function handleStateChange(){
                if(xmlHttp.readyState == 4){
                    if(xmlHttp.status == 200){
                        if(requestType == "all"){
                            listAllActivities();
                        }
                    }
                }
            }
            
            function listAllActivities(){
                var xmlDoc = xmlHttp.responseXML;
                var rootNode = xmlDoc.getElementsByTagName("activities")[0].firstChild;
                var Knoten = rootNode;
                var i = 0;
                
                while(Knoten != null){
                    i++;
                    //alert(Knoten.nodeName + " | " + Knoten.nodeType);
                    Knoten = Knoten.nextSibling;
                }
                alert(i);
            }
            
        </script>
    </head>
    <body>
        <h1>Activit&auml;ten f&uuml;r die Woche</h1>
        <form action="#" >
            <input type="button" value="Activities for this week" onClick="startRequest('all');" />
        </form>
    </body>
</html>
