So we have a XML file stored somewhere in file system and by looking at it, we can conclude that it contains list of Employee. Every Employee hasidattribute and fieldsage,name,genderandrole. We will use SAX parser to parse this XML and create a list of Employee object. Here is the Em...
This method returns the SAX parser that is encapsultated by the implementation of this class. 2 abstract Object getProperty(String name) This method returns the particular property requested for in the underlying implementation of XMLReader. 3 Schema getSchema() This method gets a reference to...
java.lang.Object javax.xml.parsers.SAXParser public abstract class SAXParser extends Object 定义包装XMLReader实现类的API。 在JAXP 1.0中,此类包装了Parser接口,但此接口已被XMLReader取代。 为了便于转换,此类继续支持相同的名称和接口以及支持新方法。 可以从SAXParserFactory.newSAXParser()方法获得此类的实例...
java.lang.Object javax.xml.parsers.SAXParser public abstract classSAXParserextendsObject XMLReader実装クラスをラップするAPIを定義します。JAXP 1.0では、このクラスはParserインタフェースをラップしましたが、このインタフェースはXMLReaderに置き換えられています。移行を簡単にするために、この...
so the amount of memory used by a DOM parser depends entirely on the size of the input data. The memory footprint of a SAX parser, by contrast, is based only on the maximum depth of the XML file (the maximum depth of the XML tree) and the maximum data stored in XML attributes on...
步骤二:创建一个SAXParserFactory对象 在Java中,我们可以使用SAXParserFactory类来创建一个SAXParser对象。下面是创建SAXParserFactory对象的代码: SAXParserFactoryfactory=SAXParserFactory.newInstance(); 1. 步骤三:使用SAXParserFactory对象创建一个SAXParser对象 ...
Running the SAX Parser Example without Validation The following steps explain how to run the SAX parser example without validation. To Run the SAXLocalNameCount Example without Validation Save the SAXLocalNameCount.java file in a directory named sax. Compile the file as follows: javac sax/SAX...

While processing the XML theSAXParsercalls methods in theDefaultHandlersubclass (here, theSaxHandler) instance corresponding to what the parser finds in the XML file. To react to those method calls you override the corresponding methods in theDefaultHandlersubclass. Here is an example: ...
