Gets a configuration attribute value from an IIS configuration section or configuration element attribute.


   [-ConfigElement] <ConfigurationElement>
   [-AttributeName] <String>


The Get-IISConfigAttributeValue cmdlet gets a configuration attribute value from an Internet Information Services (IIS) configuration section attribute or a configuration element attribute. The value returned is the value that can be extracted from the given ConfigurationElement and not necessarily the effective value for a given site / virtual directory / folder etc. To obtain the effective attribute values, always retrieve the configuration element by specifying the commit path as the deepest level possible. Even the configuration attribute is not defined at that level, the parent attributes are scanned and the effective configuration element is returned. You can then work on this ConfigurationElement to get/set/remove configuration attribute values.


Example 1: Get a configuration attribute from an IIS website

PS C:\> Get-IISSite "Default Web Site" | Get-IISConfigElement -ChildElementName "limits" | Get-IISConfigAttributeValue -AttributeName "MaxUrlSegments"

This command gets the configuration attribute MaxUrlSegments for the Default Web Site.

Example 2: Get configuration attribute values from different parts of the configuration store

PS C:\> Get-IISConfigSection "system.webServer/asp" | Get-IISConfigAttributeValue -AttributeName "ScriptErrorMessage"
An error occurred on the server when processing the URL. Please contact the system administrator. <p/> If you are the system administrator please click <a href="">here</a> to find out more about this error.

This command gets the global attribute value for ScriptErrorMessage
