¿Cómo puedo recuperar un elemento de Groovy''s GPathResult usando una cadena que contiene un periódico

Question

def elementPath = "elementA.elementB"
xml."${elementPath}".each {}

¿Cómo hacer que esto funcione? xml.elementA.elementB.each {} funciona.

Answer 1

Puedo pensar en 2 formas alrededor de esto ...

// Dummy Data for the testing
def CAR_RECORDS = ''''''
    <records>
      <car name=''HSV Maloo'' make=''Holden'' year=''2006''>
        <country>Australia</country>
        <record type=''speed''>Production Pickup Truck with speed of 271kph</record>
      </car>
      <car name=''P50'' make=''Peel'' year=''1962''>
        <country>Isle of Man</country>
        <record type=''size''>Smallest Street-Legal Car at 99cm wide and 59 kg in weight</record>
      </car>
      <car name=''Royale'' make=''Bugatti'' year=''1931''>
        <country>France</country>
        <record type=''price''>Most Valuable Car at $15 million</record>
      </car>
    </records>
  ''''''
def xml = new XmlSlurper().parseText( CAR_RECORDS )
def propNames = ''car.country''

// METHOD 1
// Split the propnames into individual properties, then use Inject to walk down this list
// Passing the result to the next property
propNames.split( //./ ).inject( xml ) { obj, prop -> obj?."$prop" }.each { println it.text() }

// METHOD 2
// Construct a string to evaluate, and pass the xml object to it (it gets substituted in place of x)
Eval.x( xml, "x.${propNames}" ).each { println it.text() }

La página de javadoc para Eval.x está aquí

Espero que esto ayude :-)

Answer 2

xml."elementA.elementB".each {}
