I am writing what should be a simple Visual Basic program, but I am having trouble navigating an XML structure. In my code, I have some lines that retrieve XML from a website in the form of a string (responseBody), which I then dumped to a file – and when the file is dragged into a browser window, the XML looks fine. Here is a portion of that XML:

<?xml version="1.0" encoding="UTF-8"?>
<weatherdata><location><name>Saline</name><type></type><country>US</country><timezone>-18000</timezone><location altitude="0" latitude="42.1698" longitude="-83.7849" geobase="geonames" geobaseid="0"></location></location><credit></credit><meta><lastupdate></lastupdate><calctime>0</calctime><nextupdate></nextupdate></meta><sun rise="2022-01-10T13:02:51" set="2022-01-10T22:22:06"></sun><forecast><time from="2022-01-11T03:00:00" to="2022-01-11T06:00:00"><symbol number="803" name="broken clouds" var="04n"></symbol><precipitation probability="0"></precipitation><windDirection deg="304" code="NW" name="Northwest"></windDirection><windSpeed mps="3.86" unit="m/s" name="Gentle Breeze"></windSpeed><windGust gust="7.49" unit="m/s"></windGust><temperature unit="kelvin" value="260.06" min="260.06" max="260.14"></temperature><feels_like value="253.06" unit="kelvin"></feels_like><pressure unit="hPa" value="1035"></pressure><humidity value="71" unit="%"></humidity><clouds value="broken clouds" all="66" unit="%"></clouds><visibility value="10000"></visibility></time><time from="2022-01-11T06:00:00" to="2022-01-11T09:00:00"><symbol number="802" name="scattered clouds" var="03n"></symbol><precipitation probability="0"></precipitation><windDirection deg="291" code="WNW" name="West-northwest"></windDirection><windSpeed mps="2.27" unit="m/s" name="Light breeze"></windSpeed><windGust gust="3.81" unit="m/s"></windGust><temperature unit="kelvin" value="260.25" min="260.25" max="260.37"></temperature><feels_like value="255.21" unit="kelvin"></feels_like><pressure unit="hPa" value="1035"></pressure><humidity value="74" unit="%"></humidity><clouds value="scattered clouds" all="29" unit="%"></clouds><visibility value="10000"></visibility></time></forecast></weatherdata>
What I would like to do is simply this: Access the max temperature for the date/time 2022-01-11 @ 4:00 (which is within the times listed in the first <time> element). Would you please show me how to do this? I have tried:
Code:
Dim xd As New XmlDocument()
xd.Load(New StringReader(responseBody))
Dim nav As XPathNavigator = xd.CreateNavigator()
but was not able to figure out how to get into the structure.
