How to find all XML elements by tag name in Groovy?

Question

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

I need to find all car elements in this document:

Answer 1

This is how it works:

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

Answer 2

You can also do:

def xml = new XmlSlurper().parse(file)
def cars = xml.'**'.findAll { it.name() == 'car' }

Answer 3

Use an XMLSlurper

def records = new XmlSlurper().parseText(file)
reco​rds.depthFirst()​.findAll { !it.childNodes() && it.car} ​

/*Otherwise this returns the values for parent nodes as well*/
