Question

Suppose I have a Web.config like such:

<configuration>
    <elmah>
        ...
    </elmah>
</configuration>

Is it possible to remove the <elmah> node with config transforms? So far I’ve tried something like:

<configuration>
    <elmah xdt:Transfrom="RemoveAll"/>
</configuration>

Which doesn’t work (according to Preview Transform). Althought this type of thing does seem to work on other nodes. Does anyone know how this can be removed?

Thanks

You need to have a xdt:Locator to get the match.

Try using the following:

Debug:

<configuration>
    <elmah name="debug" />       
</configuration>

Release:

 <configuration>
        <elmah name="debug" xdt:Locator="Match(name)" xdt:Transform="RemoveAll" />      
    </configuration>

Or without the need for name matching:

 <configuration>
            <elmah name="debug" xdt:Locator="XPath(//elmah)" xdt:Transform="RemoveAll" />      
        </configuration>

or

 <configuration>
            <elmah name="debug" xdt:Locator="XPath(configuration/elmah)" xdt:Transform="RemoveAll" />      
        </configuration>

As a note:

Currently the Web.config transforms are only applied during the Web Publish Pipleline (WPP) that is on Publish, not during debug, to enable them during debug check the following link: http://sedodream.com/2010/10/21/ASPNETWebProjectsWebdebugconfigWebreleaseconfig.aspx .

Hope it helps.
