本文整理了Java中javax.xml.parsers.SAXParser类的一些代码示例，展示了SAXParser类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。SAXParser类的具体详情如下：
包路径：javax.xml.parsers.SAXParser
类名称：SAXParser
[英]Defines the API that wraps an org.xml.sax.XMLReaderimplementation class. In JAXP 1.0, this class wrapped the org.xml.sax.Parser interface, however this interface was replaced by the org.xml.sax.XMLReader. For ease of transition, this class continues to support the same name and interface as well as supporting new methods. An instance of this class can be obtained from the javax.xml.parsers.SAXParserFactory#newSAXParser() method. Once an instance of this class is obtained, XML can be parsed from a variety of input sources. These input sources are InputStreams, Files, URLs, and SAX InputSources.
This static method creates a new factory instance based on a system property setting or uses the platform default if no property has been defined.
The system property that controls which Factory implementation to create is named "javax.xml.parsers.SAXParserFactory". This property names a class that is a concrete subclass of this abstract class. If no property is defined, a platform default will be used.
As the content is parsed by the underlying parser, methods of the given org.xml.sax.HandlerBase or the org.xml.sax.helpers.DefaultHandler are called.
Implementations of this class which wrap an underlying implementation can consider using the org.xml.sax.helpers.ParserAdapterclass to initially adapt their SAX1 implementation to work under this revised class.
[中]定义包装组织的API。xml。萨克斯。XMLReaderimplementation类。在JAXP 1.0中，这个类包装了组织。xml。萨克斯。解析器接口，但是这个接口被org所取代。xml。萨克斯。XMLReader。为了便于转换，该类继续支持相同的名称和接口，并支持新方法。这个类的一个实例可以从javax中获得。xml。解析器。SAXParserFactory#newSAXParser（）方法。一旦获得此类的实例，就可以从各种输入源解析XML。这些输入源是InputStreams、文件、URL和SAX输入源。
此静态方法基于系统属性设置创建新的factory实例，如果未定义属性，则使用平台默认值。
控制要创建哪个工厂实现的系统属性名为[$0$]。该属性命名一个类，该类是该抽象类的一个具体子类。如果未定义属性，将使用平台默认值。
当底层解析器解析内容时，给定组织的。xml。萨克斯。HandlerBase或组织。xml。萨克斯。帮手。调用DefaultHandler。
这种封装底层实现的类的实现可以考虑使用ORG。xml。萨克斯。帮手。ParserAdapterclass最初对SAX1实现进行了调整，使其能够在这个修改后的类下工作。
