Removing an XML child node 1

[BG12424]

I am having a problem removing my <UserInfo> child node from this XML format. Can anyone please provide any suggestions? Thanks

<?xml version="1.0"?>
<Locks>
  <Filing FormType="FRI" FilingType="R" EndDate="1/1/2005" FirmId="0000173">
    <UserInfo UserId="nfisbjg" Session="kvoyaz550ceqifm3btr5aoaf" />
    <UserInfo UserId="nfisbjg" Session="234kjosdfoowaef" />
</Filing>
</Locks>

Public Sub DeleteUserFromFiling()

    Dim xmlDocument As XmlDocument
    xmlDocument = LoadXmlFile()

    If ( Not xmlDocument Is Nothing ) Then        

        Dim xPathQuery As String 
        xPathQuery = "//Locks/Filing/UserInfo[@Session='" & m_SessionId & "']"

        Dim xmlNode As XmlNode
        xmlNode = xmlDocument.SelectSingleNode(xPathQuery)
'--------- PROBLEM IS HERE ------------
        xmlDocument.DocumentElement.RemoveChild(xmlNode)
        xmlDocument.RemoveChild(xmlNode)

        Dim parentNode As XmlNode
        parentNode = FindFilingByUserId(xmlDocument)
        
        'Only remove the filing element if there are not any additional
        'user session information appended as children to the filing element.
        'This enables the filing to still be active when multiple browser
        'sessions are timing out causing this routine to be called.
        If parentNode.HasChildNodes = False Then
            parentNode.RemoveAll()
        End If

        xmlDocument.Save(m_XmlFile)

    End If

End Sub

The problem with doing something right the first time is that nobody appreciates how difficult it was.

xmlDocument.DocumentElement.RemoveChild(xmlNode):
but your xmlNode is not a child of the document element.

Try something like:
xmlNode.parentNode.removeChild xmlNode

Thank you, this resolved my problem. I actually took a slightly different approach, but this helped.
