Access attribute on node which has namespace

Question

I have the xml I pasted in the post and I want to use groovy XmlSlurper to access node language with attribute xlink:href that is not null/empty. I read the xml with XmlSlurper in the following way:

 def node = xmlSlurper.parseText(xml).declareNamespace(
                xlink:"http://www.w3.org/1999/xlink"
        );

then I try to access all nodes with name and attribute and process this attribute:

node.depthFirst().findAll {
            it.name() == "language" && it["@xlink.href"]?.text().trim()
        }.each {
            println(it["@xlink.href"]?.text())
        }

@xlink.href seems to be always empty but it is there. Debugging the code I have noticed that it attribute on node language has value:

"{http://www.w3.org/1999/xlink}href" -> "http://prestashop.cartisy.com/api/languages/1"

What is the correct way to access xlink.href attribute on node language?

It's @ns:attr and not @ns.attr:

def node = new groovy.util.XmlSlurper().parseText('''\








''').declareNamespace(
    xlink:"http://www.w3.org/1999/xlink")

node.depthFirst().findAll {
    it.name() == "language" && it["@xlink:href"]?.text()?.trim()
    //                                  ~~~
}.each {
    println(it["@xlink:href"]?.text())
    //               ~~~
}
