TIKA提取XML文檔

下面給出的程序是用來從XML文檔提取內容和元數據：

import java.io.File; import java.io.FileInputStream; import java.io.IOException; import org.apache.tika.exception.TikaException; import org.apache.tika.metadata.Metadata; import org.apache.tika.parser.ParseContext; import org.apache.tika.parser.xml.XMLParser; import org.apache.tika.sax.BodyContentHandler; import org.xml.sax.SAXException; public class XmlParse { public static void main(final String[] args) throws IOException,SAXException, TikaException { //detecting the file type BodyContentHandler handler = new BodyContentHandler(); Metadata metadata = new Metadata(); FileInputStream inputstream = new FileInputStream(new File("pom.xml")); ParseContext pcontext = new ParseContext(); //Xml parser XMLParser xmlparser = new XMLParser(); xmlparser.parse(inputstream, handler, metadata, pcontext); System.out.println("Contents of the document:" + handler.toString()); System.out.println("Metadata of the document:"); String[] metadataNames = metadata.names(); for(String name : metadataNames) { System.out.println(name + ": " + metadata.get(name)); } } }

保存上述代碼保存爲XmlParse.java，並通過使用下面的命令從命令提示編譯：

javac XmlParse.java
java XmlParse

下面給出的是pom.xml文件的快照

本文檔具有以下屬性：

執行上述程序後，將得到下面的輸出。
