Answer 1

First of all, in the first expression you're referring to an element called Summary which doesn't exist in your XML.

Now if you want to use namespaces in your xpath expression, you will have to declare them in the global element called namespace-manager:

<mulexml:namespace-manager includeConfigNamespaces="false">
    <mulexml:namespace prefix="soapenv" uri="http://schemas.xmlsoap.org/soap/envelope/" />
    <mulexml:namespace prefix="out" uri="http://soap.sforce.com/2005/09/outbound" />
    <mulexml:namespace prefix="urn" uri="urn:sobject.enterprise.soap.sforce.com" />
</mulexml:namespace-manager>

Using the above and replacing Summary with something that does exist, works:

<logger level="WARN" message="#[xpath://soapenv:Envelope/soapenv:Body/out:notifications/out:Notification/out:sObject/urn:Id]" />
