I am using xdt transforms to modify my Sitecore.config file for different environments. I want to remove a role:require="!ContentDelivery" attribute.

I'm targeting the following element:

  <!-- core -->
    <database id="core" singleInstance="true" type="Sitecore.Data.DefaultDatabase, Sitecore.Kernel" role:require="!ContentDelivery">

and want to remove the role:require="!ContentDelivery" attribute.

If I use the following xdt syntax

<database id="core" singleInstance="true" type="Sitecore.Data.DefaultDatabase, Sitecore.Kernel" xdt:Locator="Match(id)" xdt:Transform="RemoveAttributes(role:require)"/>

I get the error "Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.".

If I omit the namespace prefix i.e.

<database id="core" singleInstance="true" type="Sitecore.Data.DefaultDatabase, Sitecore.Kernel" xdt:Locator="Match(id)" xdt:Transform="RemoveAttributes(require)"/>

It doesn't work.

Is there a solution to this, or perhaps a better way to solve the problem?

  • In what conditions would the transform run? Would it be less complicated to use the patching system to override based on Environment variables? blog.vitaliitylyk.com/… Oct 16, 2022 at 21:51
  • It would run at project build/compile time to generate the output Sitecore.config file. Easier solution is to just modify Sitecore.config and remove that role:require attribute, but I wanted to try and avoid modifying Sitecore.config directly. Oct 16, 2022 at 21:57

You can use Replace syntax:

<database id="core" singleInstance="true" type="Sitecore.Data.DefaultDatabase, Sitecore.Kernel" xdt:Locator="Match(id)" xdt:Transform="Replace"/>

You can find references to the details and another syntax: Web.config Transformation Syntax for Web Project Deployment Using Visual Studio

  • I did get this technique to work, so this is sometimes a good solution, but in my case, I did not want to duplicate the whole database configuration elements. Oct 17, 2022 at 8:35

xdt:Transform="RemoveAttributes(role:require)" should work correctly. But you need to remember to add xmlns:role="http://www.sitecore.net/xmlconfig/role/" attribute to the <configuration> tag of your tranform config file:

<configuration xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <database xdt:Transform="RemoveAttributes(role:require)" />
