Guys need groovy help to build a json map

Assuming that you are getting jdbc result as below xml

def jdbcData = '''<Results>
    <ResultSet fetchSize="10">
        <Row rowNumber="1">
            <ROLEID>1</ROLEID>
            <NAMEID>123</NAMEID>
            <ADDRESSID>1234</ADDRESSID>
        </Row>
        <Row rowNumber="2">
            <ROLEID>5</ROLEID>
            <NAMEID>456</NAMEID>
            <ADDRESSID>345</ADDRESSID>
        </Row>
        <Row rowNumber="3">
            <ROLEID>7</ROLEID>
            <NAMEID>2356</NAMEID>
            <ADDRESSID>6756</ADDRESSID>
        </Row>
    </ResultSet>
</Results>'''

def jsonString = new groovy.json.JsonBuilder(new XmlSlurper().parseText(jdbcData).ResultSet.Row.collect {
	[
		roleId: it.ROLEID.text(),
		nameId: it.NAMEID.text(),
		addrId: it.ADDRESSID.text()
	]	
}).toPrettyString()
log.info jsonString

In case if you have the list, you can use below:

def list = [[roleId:"1", nameId:"123", addrId:"1234"], [roleId:"5", nameId:"456", addrId:"345"], [roleId:"7", nameId:"2356", addrId:"6756"]]
def jsonString = new groovy.json.JsonBuilder(list).toPrettyString()
log.info jsonString

Either case, output will be:like as it is mentioned in the queston.

[
    {
        "roleId": "1",
        "nameId": "123",
        "addrId": "1234"
    },
    {
        "roleId": "5",
        "nameId": "456",
        "addrId": "345"
    },
    {
        "roleId": "7",
        "nameId": "2356",
        "addrId": "6756"
    }
]
