c# - 根据子节点对整个 xdocument 进行排序

Question

我有以下格式的 xml:

<?xml version="1.0" encoding="utf-8"?>
<contactGrp name="People">
  <contactGrp name="Developers">
    <customer name="Mike" ></customer>
    <customer name="Brad" ></customer>
    <customer name="Smith" ></customer>
  </contactGrp>
  <contactGrp name="QA">
    <customer name="John" ></customer>
    <customer name="abi" ></customer>
  </contactGrp>
</contactGrp>

我想根据他们的姓名对客户列表进行排序，并按以下格式返回文档:

<?xml version="1.0" encoding="utf-8"?>
<contactGrp name="People">
  <contactGrp name="Developers">
    <customer name="Brad" ></customer>
    <customer name="Mike" ></customer>
    <customer name="Smith" ></customer>
  </contactGrp>
  <contactGrp name="QA">
    <customer name="abi" ></customer>
    <customer name="John" ></customer>
  </contactGrp>
</contactGrp>

我正在使用 C#，目前使用的是 xmldocument。

谢谢

你可以这样做

var doc = XDocument.Load(/* ... */);

foreach (var g in doc.Descendants("contactGrp"))
{
    var customers = g.Elements("customer").ToList();
    customers.Remove();
    g.Add(customers.OrderBy(c => c.Attribute("name").Value));
}
