Groovy: Retrieving XML Element Attributes in a Map

The Groovy script below is a little test I came up to help me remember how to grab element attributes from an XML document. In the example message, I want the attributes from the request element in a Map:

  def message = """<message>
    <request file="/home/prystasj/file.txt" type="txt" />
  <message>"""

  def xml = new XmlParser().parseText(message)
  def attrs = xml.request[0].attributes()

  println "Class: ${attrs.getClass().getName()}"
  println "Size: ${attrs.size()}"
  println "Attributes: $attrs"
  println "File: ${attrs.file}"
  println "Type: ${attrs.type}"

The key that tripped me up was that I needed to grab the first request element (indexed at 0) in the assignment to attrs.

The output from the script:

  Class: java.util.LinkedHashMap
  Size: 2
  Attributes: [file:/home/prystasj/file.txt, type:txt]
  File: /home/prystasj/file.txt
  Type: txt
