Advanced XML manipulation

[realdadfish]

I have an XML template that contains a single publisher XML snippet that I want to dynamically expand to multiple instances of the same snippet, but of course with different configuration for each.

While I figured out that I can easily add new nodes via the leftShift operator on the projectXml, I don't seem to be able to override the child elements of the just copied nodes, because they're not yet visible.

I came up with the following workaround, but I found that rather ugly:

jenkins {
    templates {
        hockeyupload_bare {
            xml file('path/to/hockeyupload.xml')
        }
        hockeyupload_multiplied {
            xml jenkins.templates.hockeyupload_bare.override { projectXml ->
                if (project.ext.hockeyAppIds.size() > 1) {
                    (1..project.ext.hockeyAppIds.size() - 1).each {
                        projectXml.publishers << projectXml.publishers["hockeyapp.HockeyappRecorder"]
                    }
                }
            }
        }
        hockeyupload {
            xml templates.hockeyupload_multiplied.override { projectXml ->
                def item = 0
                project.ext.hockeyAppIds.each { hockeyAppid ->
                    projectXml.publishers["hockeyapp.HockeyappRecorder"][item].applications["hockeyapp.HockeyappApplication"].with {
                        // specific overrides ..
                    }
                    ++item
                }
            }
        }
    }
}

Am I missing something or should this plugin somehow gain "flush" support to avoid these kind of hacks?
