Powershell read XML value

I have the following XML, and I'm trying to obtain the value where the Name attribute is ComponentVersion. 

<Component .......>
  <Settings>
    <Setting Name="ComponentVersion" Value="12345" />
    <Setting Name="Host" Value="false" />
  </Settings>
  <Jobs>
    <Job Name="Platform" />
  </Jobs>
</Component>

I read the XML file like this:

$fullPathXML = "$env:PackagesPath\Platform\Components\SystemPlatform.Comp.xml"
[xml]$xmlSystemPlatform = Get-Content $fullPathXML

and then tried the following:

  1. $xmlSystemPlatform.selectNodes('//Settings/Setting') | select Name

  2. Select-Xml '//Settings/Setting[contains(@Name, "ComponentVersion")]' $xmlSystemPlatform |%{$_.Node.Value}

  3. $xmlSystemPlatform.Settings.Setting[0].Name $xmlSystemPlatform.Settings.Setting[0].Value

Another one-liner:

([Xml] (Get-Content "$env:PackagesPath\Platform\Components\SystemPlatform.Comp.xml")).SelectNodes("//Settings/Setting[@Name='ComponentVersion']").Value

Or if you prefer it with variable:

$xmlSystemPlatform.SelectNodes("//Settings/Setting[@Name='ComponentVersion']").Value

Using an XPath expression something like this should work:

$filename = "$env:PackagesPath\Platform\Components\SystemPlatform.Comp.xml"

[xml]$xml = Get-Content $filename

$xml.SelectNodes('//Settings/Setting[@Name = "ComponentVersion"]').Value

Note that XPath expressions are case-sensitive.
