如何在sap ui5中设置xml模型中的数组

var oModel = new sap.ui.model.xml.XMLModel();
oModel.setData({
    arrayData: [
        { name: "John", age: 30 },
        { name: "Jane", age: 25 },
        { name: "Tom", age: 35 }
    ]
});

var oView = new sap.ui.core.mvc.XMLView({
    viewName: "myView",
    models: oModel
});

<mvc:View xmlns:mvc="sap.ui.core.mvc" xmlns:core="sap.ui.core">
    <core:List items="{/arrayData}">
        <core:ListItem title="{name}" description="{age}" />
    </core:List>
</mvc:View>

var oModel = this.getView().getModel();
var aData = oModel.getProperty("/arrayData");

// 添加新的数组项
aData.push({ name: "Kate", age: 28 });

// 更新数组项的值
aData[0].age = 32;

// 重新设置模型数据
oModel.setProperty("/arrayData", aData);
