定義

表示 XML 文件中的單一節點。Represents a single node in the XML document.

備註

這個類別會實行 W3C 檔物件模型(DOM)層級1核心和核心 DOM 層級2。This class implements the W3C Document Object Model (DOM) Level 1 Core and the Core DOM Level 2. DOM 是 XML 文件的記憶體中 (快取) 樹狀結構表示。The DOM is an in-memory (cache) tree representation of an XML document. XmlNode 是 DOM 的 .NET 實作為基底類別。XmlNode is the base class in the .NET implementation of the DOM. 它支援 XPath 選取專案,並提供編輯功能。It supports XPath selections and provides editing capabilities. @No__t-0 類別會延伸 XmlNode,並代表 XML 檔。The XmlDocument class extends XmlNode and represents an XML document. 您可以使用 XmlDocument 來載入和儲存 XML 資料。You can use XmlDocument to load and save XML data. 它也包含建立節點的方法。It also includes methods for node creation. 如需詳細資訊,請參閱XML 檔物件模型(DOM)See XML Document Object Model (DOM) for more information.

重要

由於使用 XmlNode 類別而引發的例外狀況(例如,@no__t 1 類別可能包含不應在未受信任的案例中公開的機密資訊)。Exceptions raised as a result of using the XmlNode class, such as the XmlException class may contain sensitive information that should not be exposed in untrusted scenarios. 應該適當地處理例外狀況,如此一來,就不會在未受信任的案例中公開此機密資訊。Exceptions should be properly handled so that this sensitive information is not exposed in untrusted scenarios.
