Install-SPApplicationContent does not parse XML comment in webconfig xml

If you use custom webconfig files under 14/CONFIG folder to modify web application’s web.config file, then pay attention not to include any XML comment <!-- --> in the xml files.

Neither Install-SPApplicationContent nor STSADM –o copyappbincontent parse xml comments.

For example:

in 14/CONFIG/webconfig.custom.xml,  

    1: <?xml version="1.0" encoding="utf-8"?>
    2: <actions>
    3:   <remove path="configuration/appSettings/add[@key='Security.ServiceAccount']" />
    4:  
    5:   <!-- XML COMMENT CANNOT BE PARSED -->
    6:   
    7:   <add path="configuration/appSettings">
    8:     <add key="Security.ServiceAccount" value="apac\spadmin" />
    9:   </add>
   10: </actions>

Now if you run STSADM –o copyappbincontent, you would get the following error:

Object reference not set to an instance of an object.

If you run Install-SPApplicationContent, you would get the following erro:

Install-SPApplicationContent : Object reference not set to an instance of an ob ject. At line:1 char:29 + Install-SPApplicationContent <<<< + CategoryInfo : InvalidData: (Microsoft.Share...licationContent: SPCmdletInstallSPApplicationContent) [Install-SPApplicationContent], NullR eferenceException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletInstallS PApplicationContent

Remove the xml comment at line 5 in 14/CONFIG/webconfig.custom.xml will resolve this error.
