Using DOMCategory

Running the code examples in the XML chapter seems to show problems with the code and newer versions of Groovy.

My java version is 1.6.0-07 and my groovy version is 1.5.7

The example code:

document = groovy.xml.DOMBuilder.parse(new FileReader('languages.xml'))
rootElement = document.documentElement
use(groovy.xml.dom.DOMCategory)
{    
    println "Languages and authors" 
    languages = rootElement.language    
    languages.each {language ->
      println "${language.'@name'} authored by ${language.author[0].text()}" 

    }    
    def languagesByAuthor = {authorName ->
      languages.findAll {it.author[0].text() ==authorName}.collect{it.'@name'}.join(', ')}    
    println "Languages by Wirth: " + languagesByAuthor('Wirth')    
}

If I change the “println” to “System.out.println” it works fine. Is this a version problem and if so, what other examples/commands are not going to work correctly.

Thanks

Doug, good catch. Looks like a bug to me. I’ll file a JIRA. Thanks.

It’s tricky. Not failing from unit test, but fails from real code!
