XmlSlurper doesn't return value

i'm using XmlSlurper to get a value from an XML-Response. I copied the response to local String here for easier testing purposes. I need to get the value from jobReqId which is 506 in this case. If I use println: jobReqId.name(); i'm getting the correct node-name (jobReqId). If i'm using println jobReqId or println jobReqId.text(); i'm just getting empty String. Someone has an idea?

def body = """<JobApplicationAssessmentOrder>
        <JobApplicationAssessmentOrder>

           def xmlBody = new XmlSlurper().parseText(body);
           def jobReqId = xmlBody.JobApplicationAssessmentOrder.JobApplicationAssessmentOrder.jobApplication.JobApplication.jobReqId;
           println jobReqId

Your xmlBody is in the same position as the first JobApplicationAssessmentOrder node. If you do this it works:

 def jobReqId = xmlBody.JobApplicationAssessmentOrder.jobApplication.JobApplication.jobReqId

This is a common mistake, to prevent it, I always do it this way:

def JobApplicationAssessmentOrder = new XmlSlurper().parseText(body)
def jobReqId = JobApplicationAssessmentOrder.JobApplicationAssessmentOrder.jobApplication.JobApplication.jobReqId
