Can you someone help with how to get the value of date to be displayed right before the description in the code below,
thank you,
xml:
<%
strDate = "4/18/2006"
intMaxEvents = 3
Set oXMLHTTP = Server.CreateObject("Micro
oXMLHTTP.async = False
<?xml version="1.0" encoding="UTF-8"?>
<calendar>
<events>
<event date="4/17/2006">
<description>Party</descri
</event>
<event date="4/20/2006">
<description>Work</descrip
</event>
<event date="4/17/2006">
<description>Run Marathon</description>
</event>
<event date="4/17/2006">
<description>Recover</desc
</event>
<event date="4/20/2006">
<description>Another Item on another day</description>
</event>
</events>
</calendar>
ASP:
If oXMLHTTP.Load(Server.MapPa
Set oEventNodes = oXMLHTTP.documentElement.s
Response.Write "<ul>"
For i = 0 To (oEventNodes.Length - 1)
Response.Write "<li>" & oEventNodes.Item(i).Select
If i = (intMaxEvents - 1) Then Exit For
Next
Response.Write "</ul>"
Else
Response.Write "XML file did not load"
End If
Set oXMLHTTP = Nothing
%>

@deighc - Is there an advantage to doing it the way you suggested compared to the way I did it? I work a fair amount with XSL, so it seemed intuitive for me to just provide an XPath allow with the SelectSingleNode method, but I am curious if your way may have some advantages that I am not aware of...

No.
It was my understanding that attributes could only be accessed programatically through the attributes collection. I didn't realise that they were also accessible by using the SelectSingleNode() method. But this makes sense since an XML parser builds a 'node tree' from all element and attribute nodes.
So:

- @tamilgirl77, please don't accept my answer over @peterxlane's as they're functionally identical

Thank you both for helping me out,
- A node object has an attributes collection, and this collection has a getNamedItem method which returns an attribute object
- The attribute object has a value property
So, to access the 'date' attribute of the <event> node inside your For...Next loop try something like this
oEventNodes.item(i).atttri
