XPathAPI를 이용한 간단한 예제 경상대학교 컴퓨터과학과 조찬제 2005. 01. 05
XPathAPI • HOME : http://xml.apache.org/xalan-j/ • API : http://xml.apache.org/xalan-j/apidocs/ • Lib. Name : xalan.jar
XPathAPI를 사용한 예제 1 import java.io.IOException; import org.apache.xpath.XPathAPI; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException; import javax.xml.transform.TransformerException; import org.w3c.dom.Document; import org.w3c.dom.NodeList; import org.xml.sax.SAXException; public class XPathTest1 { private static final String URL = "http://blogbridge.naver.com/post/postXMLList.jsp?blogId=kelinkr"; private static final String XPATH = "//item/title/text()| //item/link/text()"; public static void main(String[] args) throws SAXException, IOException, ParserConfigurationException, TransformerException { DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); Document feed = factory.newDocumentBuilder().parse(URL); NodeList titles = XPathAPI.selectNodeList(feed, XPATH); System.out.println("<?xml version=\"1.0\"?>\r\n"); System.out.println("<XPath query=\""+XPATH+"\">\r\n"); for (int i = 0; i < titles.getLength(); i+=2) { System.out.println("\t<title>"+titles.item(i).getNodeValue()+ "</title>\r\n"); System.out.println("\t<link>"+titles.item(i+1).getNodeValue()+ "</link>\r\n"); } System.out.println("</XPath>\r\n"); } }
