Help in Groovy to compare XML Files in CPI

[former_member750254]

Hi 7a519509aed84a2c9e6f627841825b5a, engswee.yeoh

I am trying to write groovy script to compare two xml files in CPI.

Below is the code which I have written.

import com.sap.gateway.ip.core.customdev.util.Message
//Imports for DataStoreService-class
import com.sap.it.api.asdk.datastore.*
import com.sap.it.api.asdk.runtime.*
mport org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;
import org.jdom.output.XMLOutputter;
import org.xmlunit.diff;
Message processData(Message message)
{
def service = new Factory(DataStoreService.class).getService()

//Check if valid service instance was retrieved
if( service != null) {
//Read data store entry via id
def dsEntry = service.get("MetadataStorage","Metadata")
def result = new String(dsEntry.getDataAsArray())
//message.setBody(body)
def dsEntry1 = service.get("MetadataCurrent","CurrentData")
def result1 = new String(dsEntry1.getDataAsArray())
//message.setBody(body)

DifferenceEngine diff = new DOMDifferenceEngine();
diff.addDifferenceListener(new ComparisonListener() {
        public void comparisonPerformed(Comparison comparison, ComparisonResult outcome) {
            Assert.fail("found a difference: " + comparison);
        }
    });
diff.compare(result, result1);
}
   // return message
}

Below is the error I am getting , Could you please help.

Hi there

Those error messages are telling you that the runtime can't find some of the classes - specifically the JDOM and XMLUnit ones. To solve it, download the JDOM and XMLUnit JAR files and add them to your iflow on the Resources tab.

Good luck and have fun,

Morten

Hi chandrasekharkoduru450

Ah, two more things. The JDOM package is now called org.jdom2, so you need to adjust those import statements. Also, org.xmlunit.diff is a package, so to import all classes in it, use:

import org.xmlunit.diff.*

If the code itself does not work, please raise a new question with the specifics of the new problem, instead of adding new questions in this thread.

Regards,

Morten
