Ok i'm having trouble getting values from an XML document, heres the XML returned:
<?xml version="1.0"?>
<methodResponse> <params><param><value><string>
<photo id="123456508" secret="12345687e2" server="12" dateuploaded="1150921931" isfavorite="0" license="0" rotation="0" originalformat="jpg">
     <owner nsid="12336959@N00" username="BoozeSanDiego" realname="BoozeSanDiego" location="USA" />
     <title>Group</title>
     <description>Everyone in mex</description>
     <visibility ispublic="1" isfriend="0" isfamily="0" />
     <dates posted="1150921931" taken="2006-06-21 13:32:11" takengranularity="0" lastupdate="1151449682" />
     <editability cancomment="0" canaddmeta="0" />
     <comments>2</comments>
     <notes />
     <tags>
          <tag id="1239387-172173508-239" author="12336959@N00" raw="party">party</tag>
          <tag id="1239387-172173508-1725" author="12336959@N00" raw="mexico">mexico</tag>
          <tag id="1239387-172173508-42092" author="12336959@N00" raw="rosarito">rosarito</tag>
          <tag id="1239387-172173508-69612" author="12336959@N00" raw="boozing">boozing</tag>
     </tags>
     <urls>
          <url type="photopage">http://www.flickr.com/photos/boozesandiego/123173508/</url>
     </urls>
</photo>
</string></value></param></params></methodResponse>

Ok and heres my code to parse it:

      dim flickrResponse, photoset, node, Nodes, NewNode
      
      dim xmlstr
      xmlstr = replace(replace(xmlHttp.ResponseXML.xml, "&lt;", "<"),"&gt;",">")

      Const XPATH = "methodResponse/params/param/value/string/photo"
      
      Set xmlDom = Server.CreateObject("MSXML2.DOMDocument")
      'response.write "<div style='font-size:14px;'><xmp>" & xmlstr & "</xmp></div>"

      Function GetXmlValue(Node, ValueXPath)
            Dim NewNode
            
            Set NewNode = Node.selectSingleNode(ValueXPath)
            If Not NewNode Is Nothing Then
                  GetXmlValue = NewNode.Text
            Else
                  GetXmlValue = ""
            End If
      End Function



            If xmlDom.loadXML(xmlstr) Then
                  Set Nodes = xmlDom.selectNodes(XPATH)
                  If Not Nodes Is Nothing Then
                        For Each Node In Nodes %>
                              <div class="photoDetail">
                                    <img src="http://static.flickr.com/<%= node.getAttribute("server") %>/<%= node.getAttribute("id") %>_<%= node.getAttribute("secret") %>.jpg">
                                    <p><%= GetXmlValue(Node, "title")%></p>
                                    <p><%= GetXmlValue(Node, "description")%></p>
                                    <p>Image Hosted by <a href="<%= GetXmlValue(Node, "urls")%>">Flickr</a></p>
                              </div>
                  <%  Next
                  End If
            Else
                  Response.Write(xmlDom.parseError.reason)
            End If

-------------------

The problem i'm having is i'm not sure how to target different values and attibutes. Here i have managed to get values and attributes at the 'photo' level but not any lower. Also i need to loop through the tags and get each one separatly so i can make them a link

Try it like this:

Dim flickrResponse, photoset, Node, Nodes, TagNode, TagNodes

Dim xmlstr

xmlstr = replace(replace(xmlHttp.ResponseXML.xml, "&lt;", "<"),"&gt;",">")

Const XPATH = "methodResponse/params/param/value/string/photo"

Set xmlDom = Server.CreateObject("MSXML2.DOMDocument")
'response.write "<div style='font-size:14px;'><xmp>" & xmlstr & "</xmp></div>"

If xmlDom.loadXML(xmlstr) Then
   Set Nodes = xmlDom.selectNodes(XPATH)
   If Not Nodes Is Nothing Then
        For Each Node In Nodes %>
             <div class="photoDetail">
                  <img src="http://static.flickr.com/<%= node.getAttribute("server") %>/<%= node.getAttribute("id") %>_<%= node.getAttribute("secret") %>.jpg">
                  <p><%= GetXmlValue(Node, "title")%></p>
                  <p><%= GetXmlValue(Node, "description")%></p>
                  <p>Image Hosted by <a href="<%= GetXmlValue(Node, "urls")%>">Flickr</a></p>
             </div>
            <%
            Set TagNodes = Node.selectNodes("tags/tag")
            If Not TagNodes Is Nothing Then
                        For Each TagNode In TagNodes
                              Response.Write GetXmlValue(TagNode, "@id")
                              Response.Write GetXmlValue(TagNode, "@author")
                              Response.Write GetXmlValue(TagNode, "@raw")
                              Response.Write GetXmlValue(TagNode, ".")
                        Next
                  End If
                  %>
   <%  Next
   End If
Else
   Response.Write(xmlDom.parseError.reason)
End If

Function GetXmlValue(Node, ValueXPath)
  Dim NewNode
 
  Set NewNode = Node.selectSingleNode(ValueXPath)
  If Not NewNode Is Nothing Then
       GetXmlValue = NewNode.Text
  Else
       GetXmlValue = ""
  End If
End Function
