replace value in xml file

[kostukp96]

Hi. Can you please tell me how to correctly add or change values in such a file type: `<!-- IMPORTANT:

• Policy elements can appear only within the , , section elements.
• To apply a policy to the incoming request (before it is forwarded to the backend service), place a corresponding policy element within the section element.
• To apply a policy to the outgoing response (before it is sent back to the caller), place a corresponding policy element within the section element.
• To add a policy, place the cursor at the desired insertion point and select a policy from the sidebar.
• To remove a policy, delete the corresponding policy statement from the policy document.
• Position the element within a section element to inherit all policies from the corresponding section element in the enclosing scope.
• Remove the element to prevent inheriting policies from the corresponding section element in the enclosing scope.
• Policies are applied in the order of their appearance, from the top down.
• Comments within policy elements are not supported and may disappear. Place your comments between policy elements or at a higher level scope. --> https://mysite-we-dev.mysite.com https://mysite-first-we-dev.mysite.com https://mysite-dev.westeurope.cloudapp.azure.com http://localhost:9091 *

After the patch, I would like the file to be like this?

`<!-- IMPORTANT:
