    XML Problem in FireFox

    Hi all,

    I have a very basic xml file that has some customer names in it, like this:

    Code:
    <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
    <!DOCTYPE customers [
      <!ELEMENT customers (customer+)>
      <!ELEMENT customer (name)>
      <!ELEMENT name (#PCDATA)>
    ]>
    <customers>
      <customer>
        <name>Jon Doe</name>
      </customer>
      <customer>
        <name>Jane Doe</name>
      </customer>
    </customers>
    And I have a basic script file that opens the xml doc and gets the customer names:

    Code:
    function getxmldoc() {
      if (window.ActiveXObject) {
        doc = new ActiveXObject("Microsoft.XMLDOM");
        doc.async = false;
        doc.load("customers.xml");
        getnames();
      } else {
        doc = document.implementation.createDocument("","",null);
        doc.load("customers.xml");
        doc.onload = getnames;
      }
    }
    function getnames() {
      var names = doc.getElementsByTagName("name");
      alert(names.length);
      document.close();
    }
    The code works beautifully in IE7 and alerts '2' but Firefox (v2.0) alerts '0'

    Why is this happening?

    Alerts "2" in Firefox2.0 and IE7.0 for me. Make sure you aren't using a cached version of the page. Give this a shot to see if the page is cached.
    Code:
    <script type="text/javascript">
    function getxmldoc() {
      if (window.ActiveXObject) {
        doc = new ActiveXObject("Microsoft.XMLDOM");
        doc.onreadystatechange=function(){if(doc.readyState==4)getnames()};
        doc.load("customers.xml");
    
      } else if(document.implementation && document.implementation.createDocument){
        doc = document.implementation.createDocument("","",null);
        doc.load("customers.xml");
        doc.onload = getnames;
      } else if(window.XMLHttpRequest){
    xmlhttp=new XMLHttpRequest();
    xmlhttp.open("GET","customers.xml");
    xmlhttp.onreadystatechange=function(){
    if(xmlhttp.readyState!=4)return;
    if(xmlhttp.status!=200 && xmlhttp.status!=0)return;
    doc=xmlhttp.responseXML;
    getnames();
    }
    xmlhttp.send(null);
    }
    
    }
    
    /* IE support */
    if(!window.XMLSerializer){
    XMLSerializer=new Function();
    XMLSerializer.prototype.serializeToString=function(e){
    return e.xml;
    }
    }
    
    function getnames() {
    var j=new XMLSerializer();
    alert(j.serializeToString(doc))
    
    }
    getxmldoc()
    </script>

    Thanks for the info, I've also been told that FF2 requires the async=false to be set but haven't tested this yet
