解析器的目标是将 XML 转换称可读代码。

The goal of a parser is to transform XML into a readable code.

为了简化解析过程，一些商用产品可用于促进 XML 文档的分解并产生更可靠的结果。

To ease the process of parsing, some commercial products are available that facilitate the breakdown of XML document and yield more reliable results.

以下是常用的一些解析器：

Some commonly used parsers are listed below −

  1. MSXML (Microsoft Core XML Services) − This is a standard set of XML tools from Microsoft that includes a parser.

  2. System.Xml.XmlDocument − This class is part of .NET library, which contains a number of different classes related to working with XML.

  3. Java built-in parser − The Java library has its own parser. The library is designed such that you can replace the built-in parser with an external implementation such as Xerces from Apache or Saxon.

  4. Saxon − Saxon offers tools for parsing, transforming, and querying XML.

  5. Xerces − Xerces is implemented in Java and is developed by the famous open source Apache Software Foundation.
