XML node access by variable

[Carl Marcum]

I'm using XML Slurper to parse an XML file with this type of format:
<R>
  <C0>...</C0>
  <C1>...</C1>
  <C2>...</C2>
</R>
 <R>
  <C0>...</C0>
  <C1>...</C1>
  <C2>...</C2>
</R>
...

The XML file node names are constantly changing so I would like to use a 
variable for the node designations.

defreport =newXmlSlurper().parse(myXmlFile)

instead of access the C1 node like:
report.R.each() {item ->
item.C1
}

I'm using:
def myTag = "C1"
report.R.each {item ->
item.getProperty(myTag)
}

Is there a shorter way to access the node by variable without 
getProperty(tagVar)?

Thanks,
