c# xmldocument获取特定节点之后的所有兄弟节点

Question

假设我有以下xml:

<Report>
<Tablix></Tablix>
<Textbox Name="TextboxSearchInjection"></Textbox>
<Textbox></Textbox>
<Tablix></Tablix>
<Textbox></Textbox>
<Textbox Name="TextboxSearchInjectionEnd">
<Height>1</Height>
</Textbox>
<Tablix>
<Height>1</Height>
</Tablix>
<Textbox>
<Height>2</Height>
</Textbox>
<Textbox></Textbox>
<Tablix>
<Height>1</Height>
</Tablix>
<Textbox>
<Height>3</Height>
</Textbox>
</Report>

如何获得<Textbox Name="TextboxSearchInjectionEnd">之后的所有兄弟节点和使用c#中的XmlDocument在高度更新值?所以最后我将收到节点列表，如Textbox和Tablix，但从节点<Textbox Name="TextboxSearchInjectionEnd">开始。我以前不想要。

Answer 1

您可以使用NextSibling检索所有后续兄弟节点。例如,

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
var node = doc.SelectSingleNode(@"//*[@Name='TextboxSearchInjectionEnd']");
var result = GetAllSucceedingSiblingNodes(node);

其中GetAllSucceedingSiblingNodes定义为

IEnumerable<XmlNode> GetAllSucceedingSiblingNodes (XmlNode node)
{
var currentNode = node.NextSibling; // Use currentNode = node if you want to include searched node
while(currentNode!=null)
{
yield return currentNode;
currentNode = currentNode.NextSibling;
}
}

Answer 2

好的，我有一个基于你的解决方案:

private static IEnumerable<XmlNode> GetAllSucceedingSiblingNodes(XmlNode node, XmlNamespaceManager nsmgr)
{
var currentNode = node;//.NextSibling; // Use currentNode = node if you want to include searched node
while (currentNode != null &&
currentNode.Attributes["Name"].Value != "TextboxSearchInjection")
{
yield return currentNode;
currentNode = currentNode.NextSibling;
}
}

再一次非常感谢!
