    Thank you for your reply. I tried it and it works , but  it displays in single line, I want to display it like this

    <httpErrors errorMode="Custom"> 
          <remove statusCode="404" subStatusCode="-1" /> 
          <error statusCode="404" path="/test/home.aspx" responseMode="Redirect" /> 
    </httpErrors> 

    Thanks once again

    Then you must manipulate it using XML. A quick google search will be helpful

    This does not address the multiple issue that can come from trying to edit XML.

    $webConfig = Resolve-Path '.\new.config'

[xml]$xml =  Get-Content $webConfig
$node = $xml.SelectSingleNode('//httpErrors[@errorMode="Detailed"]')
$node.errorMode = 'Custom'

$frag = $xml.CreateDocumentFragment()
$frag.InnerXml = '<remove statusCode="404" subStatusCode="-1" />' 
$node.AppendChild($frag)

$frag = $xml.CreateDocumentFragment()
$frag.InnerXml = '<error statusCode="404" path="/test/home.aspx" responseMode="Redirect"/>' 
$node.AppendChild($frag)

$xml.Save($webConfig)
np $webConfig
