Hi Jim,
You should just be able to catch the Exception.
['3.5', '3.5.5', '['].each {
try {
new JsonSlurper().parseText(it)
println 'Valid'
} catch(error) {
println "Invalid: $error.message"
}
}
There are some more examples in the unit tests, e.g.:
https://github.com/apache/groovy/blob/master/subprojects/groovy-json/src/test/groovy/groovy/json/JsonSlurperTest.groovy#L260-L265
Cheers, Paul.
