Common strings in properties.xml files

I have a number of properties that share part of a string, i.e.

<!-- Codeset REST service URL -->
    <property as="xs:string" name="im.webservice.uri.codeset" value="http://localhost:8080/codesetapi/codesets" />

<!-- Eform Letters print service URL -->
    <property as="xs:string" name="im.webservice.uri.eform-letters" value="http://localhost:8080/eform-letters/generate-letter" />

Can I set a property with the value "http://localhost:8080/" and then use it in the values of other properties?

Hi Brian,

It depends; which other properties do you have in mind? (I am asking, as if those properties support XPath between brackets, aka AVTs, then you might be able to do so.)

<!-- base url for REST info server -->
    <property as="xs:string" name="im.webservice.hosturl" value="http://localhost:8080" />
<!-- Codeset REST service URL -->
    <property as="xs:string" name="im.webservice.uri.codeset" value="${im.webservice.hosturl}/codesetapi/codesets" />

I'm consuming these particular values in xbl controls, usually in a submission (this one is not using the codeset property, it is using a similarly defined info property)

                <xf:submission id="get-document-state-history" method="get" replace="instance"
                    instance="document-state-history"
                    action="{xxf:property('im.webservice.uri.info')}/documentstate/{xxf:split(xxf:get-request-path(),'/')[last()]}/history">

so I suppose I could do it there using two properties. Seems a bit messy to me.

So I gather that there is no general way to do this just in the properties to end up with a single property for the value used in the control or in a form?

thanks,

Hi Brian,

There is no mechanism to do this at the properties level. But your second property could be defined as:

<property as="xs:string" name="im.webservice.uri.codeset" value="{xxf:property('im.webservice.hosturl')}/codesetapi/codesets"/>

And when referring to its value, from XPath, you'd say: xxf:evaluate-avt(xxf:property('im.webservice.uri.codeset')).

In fact a lot of the Form Runner properties are evaluated as AVTs, which opens a number of possibilities, and the ability to refer to other properties is just one of them.
