   I’m trying to get part 3 to work with an .asp file instead of an .php, but I can’t get any value for obj.getElementsByTagName(’users’)[0] the value is null, is the users value correct ?

   I changed it to ‘data’ in this example of an xml file :

   -
   This is data

   This is the code that generates the xml :

   ” & vbNewLine
   Response.Write “” & vbNewLine
   Response.Write “This is data” & vbNewLine
   Response.Write “” & vbNewLine

   %>

   Again :

   Dit is de data

   and the code

   response.write “” & vbNewLine
   Response.Write “” & vbNewLine
   Response.Write “This is data” & vbNewLine
   Response.Write “” & vbNewLine

   Philippe, look at the output of your .asp file. Is the XML well-formed? Everything is inside some sort of <tag>? All the tags are opened and closed properly, and nothing is improperly nested? Check those things on the output of the .asp script. Your problem is most likely there.

   When I use the xml file it works fine, I then copy the xml file and add response.write before each line, adding quotes where needed, but when I replace data.xml with data.asp the code stops working.

   This is the code :

   response.write &quot &lt?xml version=&quot&quot1.0&quot&quot encoding=&quot&quotUTF-8&quot&quot?&gt&quot
   response.write &quot&ltroot&gt&quot
   response.write &quot&ltdata&gt&quot
   response.write &quotThis is some sample data. It is stored in an XML file and retrieved by JavaScript.&quot
   response.write &quot&lt/data&gt&quot
   response.write &quot&lt/root&gt&ltquot

   I’m not an ASP developer, but I believe you’ll need this line at the very beginning of your .asp file to specify the XML MIME settings for JavaScript to be able to read the output properly.
   <% Response.ContentType = "text/xml" %>
