小编cib*_*iba的帖子

我有如下从数据库中检索的对象的 json 数组

[
    { "Projectid":"A1234","ProjectLvl":1,"desc":"A1234-desc"},
    { "Projectid":"A1234.1","ProjectLvl":2,"desc":"A1234.1-desc"},
    { "Projectid":"A1234.1.1","ProjectLvl":3,"desc":"A1234.1.1-desc"},
    { "Projectid":"A1234.1.1.1","ProjectLvl":4,"desc":"A1234.1.1.1-desc"},
    { "Projectid":"A1234.2","ProjectLvl":2,"desc":"A1234.2-desc"}, 
    { "Projectid":"A1234.2.1","ProjectLvl":3,"desc":"A1234.2.1-desc"}
]

我必须创建以下 xml。您能否帮助使用 dataweave 函数以在 mule 变换组件中使用。

<projects>
    <project level="1">
        <desc>A1234-desc</desc>
        <project level="2">
            <desc>A1234.1-desc</desc>
            <project level="3">
                <desc>A1234.1.1-desc</desc>
                <project level="4">
                    <desc>A1234.1.1.1-desc</desc>
                </project>
            </project>
        </project>
        <project level="2">
            <desc>A1234.2-desc
            </desc>
            <project level="3">
                <desc>A1234.2.1-desc
                </desc>
            </project>
        </project>
    </project>
</projects>
