How I can find all elements in XML by their tag name in Groovy (GPath)?

如何通过Groovy(GPath)中的标签名称找到XML中的所有元素?

I need to find all car elements in this document:

<records>
  <first>
    <car>
      <id>378932</id>
    </car>
  </first>
  <second>
    <foo>
      <car>
       <name>audi</name>
      </car>
    </foo>
  </second>
</records>

这是我试过的和失败的:

This is what I tried and failed:

def xml = new XmlSlurper().parse(file)
assert xml.car.size() == 2


这是如何工作的:

This is how it works:

def xml = new XmlSlurper().parse(file)
def cars = xml.depthFirst().findAll { it.name() == 'car' }
assert cars.size() == 2
