Hey there.

I'm attempting to grab an XML Feed from a stat page, record it's information and display certain parts of it. Is there any example code around for dealing with XML documents?

Hello Paril,

first of all, your avatar URL is outdated: http://www.royalorigins.net/Portrait_Cloud.gif
Then, fetch the Official Scripting Documentation. It might help you.
Third, load the XML contents from its location. You can use the normal COM objects Microsoft.XMLHTTP and Microsoft.XMLDOM for it. Simply use
var objXml = new ActiveXObject("Microsoft.XMLDOM");
You will find more information about Microsoft.XMLDOM and its properties within the Microsoft Developers Network (MSDN) at http://msdn.microsoft.com/en-us/library/aa468547.aspx.
Regards,

Thanks, site must be down. Oh well. Nothing big. Haven't been here in a while.

I had checked through there, not much that I saw that helped much.

I'll take a look, thanks.

I tried this just to test it:

code:

---

function OnEvent_Initialize(MessengerStart)
{
    var objXml = new ActiveXObject("Microsoft.XMLDOM");
   
    if (objXml.Load ("http://stats.enemyterritory.com/profile/paril101?xml=true"))
    {
        Debug.Trace("Made it!\n");
    }
    else
    {
    }
}

However I got an error on it.. Is there any example code lying around of an entire one used in MsgPlus? I'm not exactly sure how I'm supposed to.. interpret this code from (what looks like) VB.

MeEtc wrote a nice tutorial how to do this: [Tutorial] Communicating with web pages. Take a look at the section "Retrieving content of a web page" before you continue. It's really worth to read it!

The only difference is that you can use the xmlhttp.responseXML property rather than xmlhttp.responseText, as this contains a nice XMLDOM object, ready for you to edit!

Here you have an example on what you can do with it:

code:

---

var url = "http://stats.enemyterritory.com/profile/paril101?xml=true";
   
Interop.Call("wininet.dll", "DeleteUrlCacheEntryW", url);
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.open("GET", url, true);
xmlhttp.onreadystatechange = function () {
   if (xmlhttp.readyState == 4) {
      if (xmlhttp.status == 200) {
         // Data from URL was retrieved successfully
         // You can now use xmlhttp.responseXML
         var xml = xmlhttp.responseXML;
         Debug.Trace("Engineer XP:"+xml.selectSingleNode("player/xp/engineer").getAttribute("xp"));
      } else {
         // The server returned an HTTP code other than 200
         Debug.Trace("ERROR!");
      }
   }
}
xmlhttp.send();

Ahh, that's perfect. Thanks. My uber-ness can take over from here.

For a wiki with what xml stuff you can do with that object I use http://www.devguru.com/technologies/xmldom/quickr...mldom_objects.html

It also gives some vb and/or jscript examples with most of the properties or methods

Okay, thanks.

Another question.. the ET:QW stats page also have some XML objects that are named the same, ie:

code:

---

<badges category="soldier" level="1">
<tasks total="600" id="1" value="8768.6899802"/>
<tasks total="2" id="2" value="87"/>
</badges>
<badges category="soldier" level="2">
<tasks total="3000" id="1" value="8768.6899802"/>
<tasks total="2000" id="2" value="2617.059387822"/>
<tasks total="20" id="3" value="87"/>
</badges>

---

How would I distinguish these apart, like getting the "total" under level "1" category "soldier" of task id "1"?

-Paril

You can easily do that by using the right statements in your search parameter for xml.selectSingleNode():

code:

---

var node = xml.selectSingleNode("badges[@category='soldier'][@level='1']/tasks[@id='1']");
var total = node.getAttribute("total");

---

The parts in green are selectors for attributes, this means that the XMLDOM engine will first look for a node with the name 'badges' and then will check if it's category-attribute equals 'soldier' and the level is '1'. If this is true, it'll look in its child nodes for 'tasks'-nodes and if it finds one with id '1', it'll return that node. Then, you can simply use the Node.getAttribute("attribute_name") method to get the 'total' attribute from the node.

Oh, cool, this is much simpler than the code Josh gave me.. thanks
