Search Query in an XML file

Hi all,

I've got an xml file that something like this:

Code:

---

<?xml version="1.0" encoding="utf-8" ?>
<AllBanks xmlns="http://tempuri.org/BankNames.xsd">
        <Bank>
                <Name>MyBank</Name>
                <FromCode>000000</FromCode>
                <ToCode>051000</ToCode>
        </Bank>
        <Bank>
                <Name>Bank1</Name>
                <FromCode>090061</FromCode>
                <ToCode>092564</ToCode>
        </Bank>
        <Bank>
                <Name>Bank2</Name>
                <FromCode>100909</FromCode>
                <ToCode>199905</ToCode>
        </Bank>
        <Bank>
                <Name>Bank3</Name>
                <FromCode>200106</FromCode>
                <ToCode>291364</ToCode>
        </Bank>
        <Bank>
                <Name>Bank4</Name>
                <FromCode>301105</FromCode>
                <ToCode>337005</ToCode>
        </Bank>
</AllBanks>

Etc etc etc.

I am creating a function that where a BranchCode will be passed into it for eg: 35656

The function needs to search in which range does the passed variable reside, then return the Name field.

What would be the best way of doing this? Currently I constructed the following. (It's really crappy I know...)

VB Code:

Function FindBankName(ByRef BranchCode As Object) As Object
        Dim doc As New Xml.XmlDocument
        Dim node As Xml.XmlNode
        Dim child As Xml.XmlNode
        Dim BankName As String
 
        BankName = ""
        doc.Load(Environment.CurrentDirectory & "\banks.xml")
        node = doc.DocumentElement
        for each Child.selectSingleNode(child::Bank)
            If (BranchCode >= node.SelectNodes(attribute::FromCode)) And (BranchCode <= node.SelectSingleNodes(Attribute::ToCode)) Then
                BankName = node.SelectNodes()
            End If
 
        Next
 
 
        'hard-code property value for testing 
        'child = node.SelectSingleNode(If (BranchCode >="00000") And (BranchCode <= "409999"))
 
 
    End Function

I have never queried a XML file before, so this is my first try... Please Help
