VBScript Can not Select XML nodes
- by urbanMethod
I am trying to Select nodes from some webservice response XML to no avail. For some reason I am able to select the root node ("xmldata") however, when I try to drill deeper("xmldata/customers") everything is returned empty! Below is the a sample of the XML that is returned by the webservice.
<xmldata>
<customers>
<customerid>22506</customerid>
<firstname>Jim</firstname>
<issuperadmin>N</issuperadmin>
<lastname>Jones</lastname>
</customers>
</xmldata>
and here is the code I am trying to select customerid, firstname, and lastname;
' Send the Xml
oXMLHttp.send Xml_to_Send
' Validate the Xml
dim xmlDoc
set xmlDoc = Server.CreateObject("Msxml2.DOMDocument")
xmlDoc.load (oXMLHttp.ResponseXML.text)
if(len(xmlDoc.text) = 0) then
Xml_Returned = "<B>ERROR in Response xml:<BR>ERROR DETAILS:</B><BR><HR><BR>"
end if
dim nodeList
Set nodeList = xmlDoc.SelectNodes("xmldata/customers")
For Each itemAttrib In nodeList
dim custID, custLname, custFname
custID =itemAttrib.selectSingleNode("customerid").text
custLname =itemAttrib.selectSingleNode("lastname").text
custFname =itemAttrib.selectSingleNode("firstname").text
response.write("News Subject: " & custID)
response.write("<br />News Subject: " & custLname)
response.write("<br />News Date: " & custFname)
Next
The result of the code above is zilch! nothing is written to the page. One strange thing is if I select the root element and get its length as follows;
Set nodeList = xmlDoc.SelectNodes("xmldata")
Response.Write(nodeList.length) '1 is written to page
It correctly determines the length of 1. However when I try the same with the next node down as follows;
Set nodeList2 = xmlDoc.SelectNodes("xmldata/customers")
Response.Write(nodeList.length) '0 is written to page
It returns a length of 0. WHY!
Please note that this isn't the only way I have attempted to access the values of these nodes. I just can not work out what I am doing wrong. Could someone please help me out. Cheers.
