Question

I have set a variable in my url wich i get in my next page, this variable is the title of an article in my xml. I have tried to get the rest of the contents in this article and misserably failed… The layout of the xml is.

    <title>
      <artist>
      Nirvana
      </artist>
      <description>
      Nirvana in concert
      </description>
      <date>
      18/05/1987
      </date>
   </title>
    <title>
    <artist>
    led zeppelin
    </artist>
    <description>
    led in concert
    </description>
    <date>
    18/05/1987
    </date>
    </title>

When i search for 18/05/1987 i want do display nirvana and led + description, so the whole content of the corresponding node.

EDIT I have tried the code and only seem to get 1 answer… im pretty new so i don’t get why i don’t get more answers when the check is itterated

    xmlDoc=loadXMLDoc("data.xml");
var hash = getUrlVars(); 
var date = hash['date'];
var nodeList = xmlDoc.getElementsByTagName("article");

for (var i = 0; i < nodeList.length; i++) {
    var titleNode = nodeList[i];
    if(titleNode.getElementsByTagName("urltext")[i].nodeValue = date){
        document.write("<div style='width:450px;'>")
        document.write("<p>"+titleNode.getElementsByTagName("title")[i].childNodes[0].nodeValue+"</p>");
        document.write("<p>"+titleNode.getElementsByTagName("description")[i].childNodes[0].nodeValue+"</p>");
        document.write("<p>"+titleNode.getElementsByTagName("urltext")[i].childNodes[0].nodeValue+"</p>");
        document.write("</div>")
    }
}

Ty in advance

Here is a little JavaScript function I use to create an XML DOM Document I can work with…

function GetXMLDoc(xml) {
    var xmlDoc;
    if (window.DOMParser) {
        var parser = new DOMParser();
        xmlDoc = parser.parseFromString(xml, "text/xml");
    }
    else // Internet Explorer
    {
        xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xml);
    }

    return xmlDoc;
}

You can then use this like so to get the title, for example…

var xmlDoc = GetXMLDoc(XML_String_Input);
var title = xmlDoc.getElementsByTagName("title")[0].nodeValue;

EDIT: As you appear to want to perform a search on the XML you can do something like this…

var nodeList = xmlDoc.getElementsByTagName("title");
var resultNodes = [];

for (var i = 0; i < nodeList.length; i++) {
    var titleNode = nodeList[i];
    if(titleNode.getElementsByTagName("artist")[0].nodeValue == "Nirvana"){
        //match found for artist "Nirvana"
        resultNodes.push(titleNode);
    }
}

//here you will now have a list (`resultNodes`) of "title" nodes that matched the search (i.e. artist == "Nirvana")
//there is enough sample code above for you to be able to process each of the seach results and gets the values for the various other properties like "data" for example
