DOM4J Select Child 个节点

Question

我有标签本，然后我读出2个节点

CCUSTBLS_KundennummerBLS

CCOMP_MandantFIBU

在此之后，我有了节点 "Lieferadresse"。现在我希望我有一个遍历节点 "Lieferadresse" 的循环。我的问题是，我经常看到所有孩子都形成了 "Lieferadresse"，而不仅仅是第一个 "Lieferadresse" 的孩子。我认为我的 Xpath 是错误的。

<?xml version="1.0" encoding="utf-8"?>
<eDoc>
    <book>
        <CCUSTBLS_KundennummerBLS>1143</CCUSTBLS_KundennummerBLS>
        <CCOMP_MandantFIBU>1</CCOMP_MandantFIBU>
        <Lieferadresse>
            <TSHIPBLS_NrLieferadresse>1</TSHIPBLS_NrLieferadresse> 
            <TCUSTBLS_Kunde>1143</TCUSTBLS_Kunde>

        </Lieferadresse>
        <Lieferadresse>
            <TSHIPBLS_NrLieferadresse>2</TSHIPBLS_NrLieferadresse> 
            <TCUSTBLS_Kunde>1143</TCUSTBLS_Kunde>

        </Lieferadresse>
        <Lieferadresse>
            <TSHIPBLS_NrLieferadresse>3</TSHIPBLS_NrLieferadresse> 
            <TCUSTBLS_Kunde>1143</TCUSTBLS_Kunde>

        </Lieferadresse>
    </book>
</eDoc>

Java Class

List<Node> nodes = document.selectNodes("/eDoc/book/child::*");
    List<Node> list = nodes;

    for (Node node : list) {
        String nodeName = node.getName();

        if("Lieferadresse".equals(nodeName)){
            List<Node> nodesDelivery = document.selectNodes("//"+nodeName+"/child::*");
            System.out.println("------------------------------------------------------");
            for(Node nodeDelivery : nodesDelivery){
                System.out.println(nodeDelivery.getName() + " " +nodeDelivery.getText());
            }

        }else{
            System.out.println(nodeName + " " +node.getText());
        }

    }

结果：

    Root element :eDoc

使用相对路径 * 并在 node 变量上调用 selectNodes 方法，例如node.selectNodes("*") (http://dom4j.sourceforge.net/dom4j-1.6.1/apidocs/org/dom4j/Node.html#selectNodes(java.lang.String)). If you know you are interested in child elements you can as well access node.elements() (http://dom4j.sourceforge.net/dom4j-1.6.1/apidocs/org/dom4j/Element.html#elements()) 如果你首先转换到 Element 节点..
