Question

我有一个xml文件

    <students>
        <student>
        <identity>
            <key>101</key>
        </identity>
        <information>
            <name>abc</name>
            <age>12</age>
            <address>xyz</address>
            .....
        </information>
        <otherinformation>
            <project>
            <name>project1</name>
            <duration>three months</duration>
            </project>
            ....... 
        </otherinformation>
        </student>
        <student>
        <identity>
            <key>102</key>
        </identity>
        <information>
            <name>def</name>
            <age>12</age>
            <address>uvw</address>
            .....
        </information>
        <otherinformation>
            <project>
            <name>project2</name>
            <duration>one month</duration>
            </project>  
        </otherinformation>
        </student>

    </students>

因此，给定密钥101的值，我想将信息节点和otherinformation复制到所有学生，无论他们拥有什么密钥。因此，在这种情况下，具有密钥102的学生将具有与复制后的密钥101中相同的信息和otherinformation节点。

我怎样才能做到这一点。？

试试这个

        XDocument d = XDocument.Parse(xml);
        var students = d.Descendants("student").ToList();
        var student101 = students.First(i => i.Element("identity").Element("key").Value == "101");

        foreach (var student in students)
        {
            student.Descendants("information").Single().ReplaceWith(student101.Descendants("information").Single());
        }

        var x = d.ToString();
