XDocument vs. XmlDocument: Which XML API Should You Choose for Your .NET Project?

.NET XML processing: The choice of xdocument and xmldocument

When dealing with XML in .NET, developers often face the problem of choosing XDocument or Xmldocume. This article aims to clarify the differences between these two XML APIs, highlighting their respective advantages and applicable scenarios.

XMLDOCUMENT: The classic DOM method

XMLDOCUMENT is the traditional XML operating document object model (DOM) API in .NET. It provides layered in XML documents to allow developers to navigate and modify their elements, attributes and text nodes. For applications that need to be compatible with the old version of the .NET version (3.0 or lower) or relying on the remaining system relying on the classic DOM API, XMLDOCUMENT is a recommended option.

xdocument: linq to xml, simple and efficient

XDocument is part of the language integration query (Linq) to XML framework introduced in .NET 3.5. It provides a simpler and more expressive XML operation grammar. Unlike the XMLDOCUMENT, which needs to be explicitly created and operating nodes, the XDocument uses a functional programming style and can use a more declarative method to build an XML document. This simplifies the creation and conversion of complex XML structures, making it the first choice for modern .NET applications.

Main differences and advantages

The simplicity of creating and modifying:

The functional programming style of XDocument makes it easier to create and modify XML documents. Its grammar reduces the number of code lines required, thereby generating a more concise and easy -to -read code. LINQ Integration:

XDocument is seamlessly integrated and linq, allowing developers to use powerful LinQ functions to efficiently query, operate and convey XML data.

Naming Space Management: Xdocume provides an intuitive way to handle the XML naming space and simplify the creation and operation of the elements and attributes of the naming space.

Stream support: Although these two APIs are mainly used for memory processing, XDocument contains the XSTREAMINEEELEMENT class, which allows delayed output to large XML documents. This allows high -efficiency to process large XML data without being completely loaded into memory.

Use scene:

The situation of selecting xdocument:

Create or modify the XML document dynamically and efficiently.

Processing complex XML structures and using linq for processing.

Simplify the XML processing of large data sets with XSTREAMINEEELEMENT.

Choose Xmldocument:
• It needs to be compatible with the old version .NET version or retention system.

It requires the traditional DOM API to accurately operate the XML node and hierarchical structure.

The application requires a specific function of XMLDOCUMENT, such as XPathNavigator.
