Some common tasks can also be performed with one of the higher level tools that avoid the need to read or edit XML.

To enable stonith for example, one could run:

crm_attribute --attr-name stonith-enabled --attr-value true

Or to see if somenode is allowed to run resources, there is:

crm_standby --get-value --node-uname somenode

Or to find the current location of my-test-rsc one can use:

crm_resource --locate --resource my-test-rsc
