在Groovy / Java中递归解析XML

Question

I have the following .XML file:

<testItems>
<children>
    <testItem name=TestSuite1>
        <children>
            <testItem name=test1>
            </testItem>
            <testItem name=test2>
            </testItem>
            <testItem name=test3>
            </testItem>
        </children>
    </testItem>
    <testItem name=TestSuite2>
        <children>
            <testItem name=test3>
            </testItem>
            <testItem name=test4>
            </testItem>
            <testItem name=test5>
            </testItem>
        </children>
    </testItem>
</children>

I want to implement java / groovy recursive algorithm that will visit each node, no matter the depth (in the example the maximum depth is 2, but it can vary)

So far I have:

root.testItems.children.testItem.each{testItem ->
...rest of code...
}

which will visit TestSuite1 and TestSuite2, but I want it to visit all nodes recursively.

Any help is much appreciated!

Answer 1

def root = new XmlParser().parseText(...)
root.depthFirst().each{e->
    //do something with each element
}
