This example assumes the following class is already on your CLASSPATH:
XmlExamples.groovy
class XmlExamples {
static 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>
'''
}
Here is an example of using XmlParser:
def records = new XmlParser().parseText(XmlExamples.CAR_RECORDS) def allRecords = records.car.size() assert allRecords == 3 def allNodes = records.depthFirst().size() assert allNodes == 10 def firstRecord = records.car[0] assert 'car' == firstRecord.name() assert 'Holden' == firstRecord.'@make' assert 'Australia' == firstRecord.country.text() // 2 cars have an 'e' in the make assert 2 == records.car.findAll{ it.'@make'.contains('e') }.size() // makes of cars that have an 's' followed by an 'a' in the country assert ['Holden', 'Peel'] == records.car.findAll{ it.country.text() =~ '.*s.*a.*' }.'@make' // types of records assert ['speed', 'size', 'price'] == records.depthFirst().grep{ it.'@type' }.'@type' // update to show what would happen if 'New Zealand' bought Holden firstRecord.country[0].value = ['New Zealand'] assert 'New Zealand' == firstRecord.country.text() // names of cars with records sorted by year assert ['Royale', 'P50', 'HSV Maloo'] == records.car.sort{ it.'@year'.toInteger() }.'@name'
It is also possible to parse XML documents using namespaces:
def ns = new groovy.xml.Namespace("http://www.example.com/book", 'ns') def root = new XmlParser().parseText("...") def authors = root[ns.book][ns.author]
