CSV to XML Example (Manual)

CSV to XML Example (Manual)

This script example is contributed by Suraj Shelke.

It illustrates how you can work with splitting, arrays, and loops in Groovy.

Since there might be many edge cases with CSV, you should also consider using a library like Apache Commons CSV.

Script

Try it on Groovy IDE 
import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import groovy.xml.XmlUtil

def Message processData(Message message) {
    //Body 
    def body = message.getBody(String);

    def lines = body.trim().split('\n')
    def headers = lines[0].split(',')
    def data = lines[1..-1].collect { it.split(',') }

    def xml = new StringBuilder()

    xml.append('<root>')
    data.each {
        row ->
            xml.append('<record>')
        headers.eachWithIndex {
            header,
            index ->
            xml.append("<${header}>${row[index]}</${header}>")
        }
        xml.append('</record>')
    }
    xml.append('</root>')

    def formattedXml = XmlUtil.serialize(xml.toString())

    message.setBody(formattedXml)
    return message;
}
