#!/usr/bin/env groovy

def csvdata = []
new File("test.csv").eachLine { line ->
    csvdata << line.split(",")
}

def headers = csvdata[0]
def dataRows = csvdata[1..-1]

def xml = new groovy.xml.MarkupBuilder()

// write "root" element
xml.root {
    dataRows.eachWithIndex { dataRow, index ->
        // write "entry" element with "id" attribute
        entry(id:index+1) {
            headers.eachWithIndex { heading, i ->
                // write each heading with associated content
                "${heading}"(dataRow[i])
            }
        }
    }
