Question

I have the following code that loads an XML file into a datatable (I went this route because I do not know how to query XML directly). I want to use the Select method to return a row where “age = 72”. However, I can’t seem to get this to work. Any ideas? Also, if there is a better way to search through a datatable for specifc values that would not require iterating through the whole table to get the results please let me know.

Imports System.Xml

Module Module1

Sub Main()
    Dim settings As New XmlReaderSettings
    settings.IgnoreWhitespace = True
    settings.IgnoreComments = True

    Dim xmlFile As XmlReader
    xmlFile = XmlReader.Create("..\..\XMLFile1.xml", settings)

    Dim ds As New DataSet
    Dim dt As New DataTable
    ds.ReadXml(xmlFile)

    dt = (ds.Tables("Age"))
    dt.TableName = "MainRMDTable"

    Dim dtValue() As DataRow
    Dim filter As String = "age = 72"
    dtValue = dt.Select(filter)

    Console.ReadLine()

End Sub

End Module

Update with the solution.

I needed to put single quotes around 72.
