Question

这是我在Stack上的第一篇文章，所以如果出现问题，请耐心等待......

好的，我的问题是如何编写带有值的XML属性。结果将是这样的：

<GroupAttribute>
<Attribute name = "Color"> Pink </Attribute>
.....
</GroupAttribute>

我试过了：

Element attribute = doc.createElement ("attribute");
groupAttribute.appendChild (attribute);
attribute.setAttribute ("attributeType" p.attributeColor);
groupAttribute.appendChild (getCompanyElements (doc, attribute, "attribute", p.attributeColor));

但它不起作用..结果是：

<GroupAttribute>
    <Attribute> Pink </Attribute>    
    .....
    </GroupAttribute>

缺少setAttribute ... 我做错了什么？

    private static Element getProductElement(Document doc /*String localizedFor,*/, Producto p) {

        Element attribute = doc.createElement("attribute");
        groupAttribute.appendChild(attribute);
        attribute.setAttribute("attributeType", p.attributeColor);
        groupAttribute.appendChild(getElements(doc, attribute, "attribute", p.attributeColor));
        return groupAttribute;

    private static Node getElements(Document doc, Element element, String name, String value) {
        Element node = doc.createElement(name);
        node.appendChild(doc.createTextNode(value));
        return node;
    }
}

这里是Producto类：

public class Producto {
        public String attributeColor;
}

Answer 1

我只是想添加评论，但我正在写这个答案，因为我还没有这个特权。我想要将属性添加到xml节点，我发现了这篇文章。

        dependency = dom.createElement("dependency");
        dependency.setAttribute("type", "value");
        dependencies.appendChild(dependency);

我在设置属性后添加了孩子。

java用值写xml属性
