Zer*_*ool 14 c# sorting linq-to-xml
我有一个XDocument,我想按字母顺序对所有元素进行排序.这是结构的简化版本:
<Config>
<Server>
<Id>svr1</Id>
<Routing>
<RoutingNodeName>route1</RoutingNodeName>
<Subscription>
<Id>1</Id>
</Subscription>
<RoutingParameters id="Routing1">
<Timeout>7200</Timeout>
</RoutingParameters>
</Routing>
<Storage>
<Physical>HD1</Physical>
</Storage>
</Server>
<Applications>
<Services>
<Local></Local>
</Services>
</Applications>
</Config>

我想在各个级别对这些文档中的元素进行排序,到目前为止我能够像这样对它进行排序:
private static XDocument Sort(XDocument file)
{
return new XDocument(
new XElement(file.Root.Name,
from el in file.Root.Elements()
orderby el.Name.ToString()
select el));
}

哪个产生:
<Config>
<Applications>
<Services>
<Local></Local>
</Services>
</Applications>
<Server>
<Id>svr1</Id>
<Routing>
<RoutingNodeName>route1</RoutingNodeName>
<Subscription>
<Id>1</Id>
</Subscription>
<RoutingParameters id="Routing1">
<Timeout>7200</Timeout>
</RoutingParameters>
</Routing>
<Storage>
<Physical>HD1</Physical>
</Storage>
</Server>
</Config>

我希望能够以相同的方式对所有子元素进行排序(理想情况下通过递归函数).任何想法我怎么能用LINQ得到这个?
谢谢你的任何想法.

您已经有了一种方法来对元素进行排序.只需递归应用它:
private static XElement Sort(XElement element)
{
return new XElement(element.Name,
from child in element.Elements()
orderby child.Name.ToString()
select Sort(child));
}
private static XDocument Sort(XDocument file)
{
return new XDocument(Sort(file.Root));
}

请注意,这会从文档中删除所有非元素节点(属性,文本,注释等).
如果要保留非元素节点,则必须将它们复制到:
private static XElement Sort(XElement element)
{
return new XElement(element.Name,
element.Attributes(),
from child in element.Nodes()
where child.NodeType != XmlNodeType.Element
select child,
from child in element.Elements()
orderby child.Name.ToString()
select Sort(child));
}
private static XDocument Sort(XDocument file)
{
return new XDocument(
file.Declaration,
from child in file.Nodes()
where child.NodeType != XmlNodeType.Element
select child,
Sort(file.Root));
}

这种方法可以实现真正的文档扩展并保留属性和文本值
我想出了这个基于几个不同的帖子和代码来自这里和那里...感谢所有贡献的人!
在同一个命名空间(不是同一个类)中添加以下内容......
public static void Sort(this XElement source, bool bSortAttributes = true)
{
//Make sure there is a valid source
if (source == null) throw new ArgumentNullException("source");
//Sort attributes if needed
if (bSortAttributes)
{
List<XAttribute> sortedAttributes = source.Attributes().OrderBy(a => a.ToString()).ToList();
sortedAttributes.ForEach(a => a.Remove());
sortedAttributes.ForEach(a => source.Add(a));
}
//Sort the children IF any exist
List<XElement> sortedChildren = source.Elements().OrderBy(e => e.Name.ToString()).ToList();
if (source.HasElements)
{
source.RemoveNodes();
sortedChildren.ForEach(c => c.Sort(bSortAttributes));
sortedChildren.ForEach(c => source.Add(c));
}
}

要使用文档扩展名...
//Load the xDoc
XDocument xDoc = XDocument.Load("c:\test.xml");
//Sort the root element
xDoc.Root.Sort();
