How do you reference an xml node by name? I want to reference "author" specifically by name.
<document>

  <item>

    <title>Chief</title>

    <author>Larry X.</author>

    <price>45.00</price>

  </item>
 

  <item>

    <title>Captain</title>

    <author>Larry X.</author>

    <price>59.00</price>

  </item>

</document>
 
 

Set xmlObj = Server.CreateObject("MSXML2.FreeThreadedDOMDocument")

xmlObj.async = False

xmlObj.setProperty "ServerHTTPRequest", True

xmlObj.Load("http://domain.com/xml.xml")

If xmlObj.parseError.errorCode <> 0 Then

	Response.Write "Sorry, newsfeed is unavailable"

End If

Set xmlList = xmlObj.getElementsByTagName("item")

Set xmlObj = Nothing

For Each xmlItem In xmlList

	Response.Write "<br>"

	Response.Write xmlItem.getElementsByID("author") & "<br>"

Next

Set xmlList = Nothing

Your first options doesn't work
Object doesn't support this property or method: 'text'

Your second option won't work in my case because the fields may be in different orders depending on the xml file I am retrieving.

ok.  try this:


Set xmlObj = Server.CreateObject("MSXML2.FreeThreadedDOMDocument")

xmlObj.async = False

xmlObj.setProperty "ServerHTTPRequest", True

xmlObj.Load("http://domain.com/xml.xml")

If xmlObj.parseError.errorCode <> 0 Then

	Response.Write "Sorry, newsfeed is unavailable"

End If

Set xmlList = xmlObj.getElementsByTagName("item")

For i = 0 To xmlList.ChildNodes.Length - 1

	Response.Write "<br>"

	Response.Write xmlList.ChildNodes.Item(i).getElementsByTagName("author").text & "<br>"
