Update Handlers Section in Web Config through PowerShell

Hi,

There was a requirement of updating our timer job config with the below values in app settings section.

Post that we are referring the values in our web part.

<add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerDocx" verb="*" path="*.docx" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerDoc" verb="*" path="*.doc" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerPPTX" verb="*" path="*.pptx" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerPPT" verb="*" path="*.ppt" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerXLSX" verb="*" path="*.xlsx" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerXLS" verb="*" path="*.xls" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerPDF" verb="*" path="*.pdf" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

      <add name="HttpHandler.Layouts.HttpHandler.MyCustomHandlerJPG" verb="*" path="*.jpg" type="HttpHandler.Layouts.HttpHandler.MyCustomHandler, HttpHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken= 6a49ec3306142af9" resourceType="Unspecified" />

Now for these entries we had created the below PowerShell script

if ((Get-PSSnapin -Name Microsoft.SharePoint.Powershell -ErrorAction SilentlyContinue) -eq $null )

{

            Add-PSSnapin Microsoft.SharePoint.Powershell

}

Write-Host "Entered???"

$WebAppConfigPath = "C:\inetpub\wwwroot\wss\VirtualDirectories\80\web.config"

Write-Host "Loading Web.Config as XML in " $WebAppConfigPath -ForegroundColor Cyan

[xml]$xml = Get-Content $WebAppConfigPath

Write-Host "Started" -ForegroundColor Green

$handlersNode =$xml.SelectSingleNode("//configuration/system.webServer/handlers")

if ($handlersNode -eq $null)

{

Write-Host "Inside if loop" -ForegroundColor Green

$addhandlersNode=$xml.CreateNode('element',"handlers","")

$handlersNode=$xml.SelectSingleNode("//configuration/system.webServer").AppendChild($addhandlersNode)

}

##region to add entries into Handlers section.
