删除父节点标记，但保持子节点，xslt

Question

我的输入xml如下所示，我想删除节点<multimap:Message1>和

<multimap:Messages xmlns:multimap="http://sap.com/xi/XI/SplitAndMerge">

但是想让孩子保持原样。

由于在multimpap和Message之间有特殊字符“：”，我无法删除此节点

<?xml version="1.0" encoding="UTF-8"?>
<multimap:Messages xmlns:multimap="http://sap.com/xi/XI/SplitAndMerge">`This one need to be removed`
    <multimap:Message1> `This one need to be removed`
        <EmployeeTime>
            <EmployeeTime>
                <externalCode>e82baef39</externalCode>
