How can i find a @param that matches with a textCase property value?

Hi all

After some attemps, finally got the Solution from an old thread from 2015 where nmrao post the solution to my question.

https://community.smartbear.com/t5/SoapUI-Open-Source/How-to-extract-value-from-response-compare-it-write-result-as/m-p/104944/highlight/true#M18272

So, Just to post the Solution, this is the code that solved my question

def DateItinWithFlights = new XmlSlurper().parseText(context.response)."**".find{ 
	it.SelectedSailing."**".find{
		            it.'@RegionCode'.text() == context.testCase.getPropertyValue('Region_con_vuelo_a_elegir')
		}
 }SelectedSailing.@Start?.text()
context.testCase.setPropertyValue('SailingDate', DateItinWithFlights)

Thanks
