Jenkins...Modify XML Tag value in xml file using Groovy in Jenkins

Question

I am using jenkins for automated deployment.

I needs to modify xml tag value in xml file using groovy script. I am using below groovy code. When I try to edit xml tag value I am receiving error unclassified field xml.uti.node error.

Node xml = xmlParser.parse(new File("c:/abc/test.xml"))
xml.DeployerServer.host[0] = '172.20.204.49:7100'
FileWriter fileWriter = new FileWriter("c:/abc/test.xml")
XmlNodePrinter nodePrinter = new XmlNodePrinter(new PrintWriter(fileWriter))
nodePrinter.setPreserveWhitespace(true)
nodePrinter.print(xml)

I need to modify host tag value and host is available inside DeployerServer tag.

Any help will be much appreciated.

Here is the script, comments in-line:

//Create file object
def file = new File('c:/abc/test.xml')
//Parse it with XmlSlurper
def xml = new XmlSlurper().parse(file)
//Update the node value using replaceBody
xml.DeployerServer.host[0].replaceBody '172.20.204.49:7100'
//Create the update xml string
def updatedXml = groovy.xml.XmlUtil.serialize(xml)
//Write the content back
file.write(updatedXml)
