lox xml - data

, når du sender xml - data via http, det giver mening at anvende lox at håndtere indgående og udgående xml - dokumenter, f.eks. rss dokumenter.som en xml - dokument blot er en flok tekst, at skabe en gennem en lox er ikke sværere end at skabe en html dokument. og sender xml - fra en lox: kan du sende xml - indhold ved hjælp af jsps på samme måde, som du sende html.den eneste forskel er, at de skal fastsætte indholdet af din side til tekst /xml.To set the content type, use the <%@page%> tag, like this:, <%@ page contentType="text/xml" %> ,Following is a simple example to send XML content to the browser:, <%@ page contentType="text/xml" %> <books> <book> <name>Padam History</name> <author>ZARA</author> <price>100</price> </book> </books> ,Try to access above XML using different browsers to see the document tree presentation of the above XML.,Processing XML in JSP:,Before you proceed with XML processing using JSP, you would need to copy following two XML and XPath related libraries into your <Tomcat Installation Directory>\\lib:, ,,,XercesImpl.jar:, Download it from http://www.apache.org/dist/xerces/j/,,,,xalan.jar:, Download it from http://xml.apache.org/xalan-j/index.html,, ,Let us put following content in books.xml file:, <books> <book> <name>Padam History</name> <author>ZARA</author> <price>100</price> </book> <book> <name>Great Mistry</name> <author>NUHA</author> <price>2000</price> </book> </books> ,Now try the following main.jsp, keeping in the same directory:, <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %> <html> <head> <title>JSTL x:parse Tags</title> </head> <body> <h3>Books Info:</h3> <c:import var="bookInfo" url="http://localhost:8080/books.xml"/> <x:parse xml="${bookInfo}" var="output"/> <b>The title of the first book is</b>: <x:out select="$output/books/book[1]/name" /> <br> <b>The price of the second book</b>: <x:out select="$output/books/book[2]/price" /> </body> </html> ,Now try to access above JSP using http://localhost:8080/main.jsp, this would produce following result:, ,Books Info:,The title of the first book is,:Padam History ,The price of the second book,: 2000 ,Formatting XML with JSP:,Consider the following XSLT stylesheet style.xsl:, <?xml - version = "0"?> <xsl:stylesheet xmlns:xsl= "http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:apply-templates/> </body> </html> </xsl:template> <xsl:template match="books"> <table border="1" width="100%"> <xsl:for-each select="book"> <tr> <td> <i><xsl:value-of select="name"/></i> </td> <td> <xsl:value-of select="author"/> </td> <td> <xsl:value-of select="price"/> </td> </tr> </xsl:for-each> </table> </xsl:template> </xsl:stylesheet> ,Now consider the following JSP file:, <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %> <html> <head> <title>JSTL x:transform Tags</title> </head> <body> <h3>Books Info:</h3> <c:set var="xmltext"> <books> <book> <name>Padam History</name> <author>ZARA</author> <price>100</price> </book> <book> <name>Great Mistry</name> <author>NUHA</author> <price>2000</price> </book> </books> < /c: > < c = import url: http: //localhost: 8080 /stil. xsl »var = "xslt" /> < x: omdanne xml - = "$(xmltext}" xslt = "$(xslt}" /> < /organ > < /html >, vil det føre til følgende resultat:,, bøger info:,, padam historie, zara100, store mistry, nuha2000, nærmere oplysninger om xml - forarbejdning af jstl, kan du tjekke lox standard et bibliotek,
