error while Parsing XML using VBA

Hi Gurus,
I am new to VBA.I am trying to create some tool using VBA to read xml documents.

The code is giving error when i try to read an XML document which contains some commented code.

the code i am using is:

Sub get_Jndi_Location()
    Dim oXmlDoc As DOMDocument
           Dim oXmlNode As IXMLDOMNode
           Dim oXmlNodes As IXMLDOMNodeList
           Set oXmlDoc = New DOMDocument
           Dim brtn As Boolean
           Dim onode As IXMLDOMElement
                     
           oXmlDoc.Load ("D:\User\WorkSpace\excel_xml\DB_API_FPC_CREATE_SR_GENERIC.wsdl")
           
           serviceName = "DB_API_FPC_CREATE_SR_GENERIC.wsdl"
           
           For Each onode In oXmlDoc.selectNodes("//service")
                Debug.Print serviceName
                    For Each portNode In onode.childNodes
                        For Each locationNode In portNode.childNodes
                            Debug.Print locationNode.getAttribute("location")
                        Next locationNode
                    Next portNode
           Next
End Sub

The XML Document i am trying to read is :

<definitions
     name="DB_API_FPC_CREATE_SR_GENERIC"
     targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/db/DB_API_FPC_CREATE_SR_GENERIC/"

        </port>
    </service>
  <plt:partnerLinkType name="DB_API_FPC_CREATE_SR_GENERIC_plt" >
    <plt:role name="DB_API_FPC_CREATE_SR_GENERIC_role" >
      <plt:portType name="tns:DB_API_FPC_CREATE_SR_GENERIC_ptt" />
    </plt:role>
  </plt:partnerLinkType>
</definitions>

I am trying to read the attribute of <jca:address location="fai/ebiz/db/ph2rel2"/> element

when i try to remove the comments the code is working.other wise it is giving the error Object doesn't support this property or method error.

Please do the needful.
Thanks in advance.
