[thelist] xmlrequest & reading xml data

Thu Oct 13 23:56:03 CDT 2005

hi evolt

im having trouble reading in more than one tag in xml.

at the moment the following (see code below) works with a xml document 
with one tag

<inset>some text</text>

(contents of photocollection-withdata.xml)

but if i have more say:

<photo><inset>some text</text><caption>new york</caption></photo>

it wont be able to find inset with the error "no properties".

 var photoinfo =  
xmlcontent.getElementsByTagName("inset").item(0).firstChild.data;

why is getElementsByTagName not able to read a document with more than 
one xml tag?

i thought perhaps its something to do with the loadXMLDoc function.

thanks,

Alex

function loadXMLDoc(url)
{
// code for Mozilla, etc.
if (window.XMLHttpRequest)
  {
  xmlhttp=new XMLHttpRequest();
  xmlhttp.onreadystatechange=state_Change;
  xmlhttp.open("GET",url,true);
  xmlhttp.send(null);
  }
// code for IE
else if (window.ActiveXObject)
  {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP")
    if (xmlhttp)
    {
    xmlhttp.onreadystatechange=state_Change;
    xmlhttp.open("GET",url,true);
    xmlhttp.send();
    }
  }
}

function state_Change()
{
// if xmlhttp shows "loaded"
if (xmlhttp.readyState==4)
  {
  // if "OK"
  if (xmlhttp.status==200)
  {
  alert("XML data OK")
  var xmlcontent = xmlhttp.responseXML;

 var photoinfo =  
xmlcontent.getElementsByTagName("inset").item(0).firstChild.data;

  document.write(photoinfo);

  }
  else
  {
  alert("Problem retrieving XML data:" + xmlhttp.statusText);
  }
  }
}

</script>
</head>

<body onload="loadXMLDoc('photocollection-withdata.xml')">

<span id="content"></span>
</p>
