此处是使用StreamingMarkupBuilder来创建一个新XML的示例：
// require(groupId:'xmlunit', artifactId:'xmlunit', version:'1.1beta2') import groovy.xml.StreamingMarkupBuilder import org.custommonkey.xmlunit.* def xml = new StreamingMarkupBuilder().bind{ records { car(name:'HSV Maloo', make:'Holden', year:2006) { country('Australia') record(type:'speed', 'Production Pickup Truck with speed of 271kph') } car(name:'P50', make:'Peel', year:1962) { country('Isle of Man') record(type:'size', 'Smallest Street-Legal Car at 99cm wide and 59 kg in weight') } car(name:'Royale', make:'Bugatti', year:1931) { country('France') record(type:'price', 'Most Valuable Car at $15 million') } } } XMLUnit.ignoreWhitespace = true def xmlDiff = new Diff(xml.toString(), XmlExamples.CAR_RECORDS) assert xmlDiff.similar()
此处我们使用了XMLUnit来比较我们创建的XML和示例XML的区别，要想上述示例生效，需要确保示例XML是有效的，比如将下边的类加到你的CLASSPATH中:
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> ''' }
下边是另外一个演示如何产生混合内容（mixed content）的示例：
// require(groupId:'xmlunit', artifactId:'xmlunit', version:'1.1beta2') import groovy.xml.StreamingMarkupBuilder import org.custommonkey.xmlunit.* def message = ' <b>wins</b> ' def xml = new StreamingMarkupBuilder().bind{ html() { body(bgcolor:'red') { h1('In Breaking News ...') p { a(href:'http://groovy.codehaus.org', 'Groovy') mkp.yieldUnescaped message a(href:'http://jax-award.de/jax_award/gewinner_eng.php', 'Jax') mkp.yield ' praise & award.' } } } } def expected = ''' <html> <body bgcolor='red'> <h1>In Breaking News ...</h1> <p> <a href='http://groovy.codehaus.org'>Groovy</a> <b>wins</b> <a href='http://jax-award.de/jax_award/gewinner_eng.php'>Jax</a> praise & award. </p> </body> </html> ''' XMLUnit.ignoreWhitespace = true def xmlDiff = new Diff(xml.toString(), expected) assert xmlDiff.similar()
