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 <inbound>, <outbound>, <backend> 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 <inbound> 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 <outbound> 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 <base> element within a section element to inherit all policies from the corresponding section element in the enclosing scope. - Remove the <base> 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. --> <policies> <inbound> <base /> <check-header name="Authorization" failed-check-httpcode="401" failed-check-error-message="Not authorized" ignore-case="false" /> <rate-limit-by-key calls="100" renewal-period="60" counter-key="@(context.Request.Headers.GetValueOrDefault("Authorization","").Substring("Bearer ".Length).AsJwt()?.Subject)" /> <cors allow-credentials="true"> <allowed-origins> <origin>https://mysite-we-dev.mysite.com</origin> <origin>https://mysite-first-we-dev.mysite.com</origin> <origin>https://mysite-dev.westeurope.cloudapp.azure.com</origin> <origin>http://localhost:9091</origin> </allowed-origins> <allowed-methods> <method>*</method> </allowed-methods> <allowed-headers> <header>*</header> </allowed-headers> <expose-headers> <header>*</header> </expose-headers> </cors> </inbound> <backend> <base /> </backend> <outbound> <base /> </outbound> <on-error> <base /> </on-error> </policies>

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

<!-- IMPORTANT: - Policy elements can appear only within the <inbound>, <outbound>, <backend> 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 <inbound> 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 <outbound> 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 <base> element within a section element to inherit all policies from the corresponding section element in the enclosing scope. - Remove the <base> 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.

Can you help me ?
