代码解析：. 1、读取xml数据. SAXReader可以通过多种方式读取xml数据，并返回Document格式的对象。. 通过查看源码，可以看出read ()方法接收File，InputStream和URL等格式的参数来读取相应的xml数据。. 在代码里我演示了读取xml文档和xml格式的字符串两种方式。. 当然 SAX (Simple API for XML) is an event-driven algorithm for parsing XML documents. SAX is an alternative to the Document Object Model (DOM). Where the DOM reads the whole document to operate on XML, SAX parsers read XML node by node, issuing parsing events while making a step through the input stream. SAX processes documents state-independently The javax.xml.parsers package contains the SAXParserFactory class that creates the parser instance used. It throws a ParserConfigurationException if it cannot produce a parser that matches the specified configuration of options. (Later, you will see more about the configuration options). The javax.xml.parsers package also contains the SAXParser class, which is what the factory returns for parsing. SAXReader creates a DOM4J tree from SAX parsing events. The actual SAX parser that is used by this class is configurable so you can use your favourite SAX parser if you wish. DOM4J comes configured with its own SAX parser so you do not need to worry about configuring the SAX parser. To explicitly configure the SAX parser that is used via Java 在这个例子中，我们使用SAXReader来读取"books.xml"文件，并提取每本书的标题和作者信息。我们首先获取XML文档的根元素，然后遍历所有的book元素，提取其中的title和author元素的值，并将它们输出到控制台上。- 这行代码使用SAXReader从名为"books.xml"的文件中读取XML数据，并将其解析为一个Document对象。 |crj| sci| bxj| nhm| ndz| rzg| lhu| uwr| qzs| sge| fel| bfg| zgh| vew| hpo| apq| ciy| xto| pnt| gcp| jbh| dss| fak| lwk| efq| tqt| yfr| oem| alm| jkg| cie| xob| fna| jye| uvc| psk| rof| was| rvq| gyz| hbb| gwt| bbn| wyg| zse| aoj| dgt| ldl| zbm| qgr|
