1, the following is an XML file used by the example: / ** * Located in the root directory of the C drive * abc.xml ** / jhgjg </ title> <content> jhjg </ content> <email> jhjh </ email> </ message> <message id = "fdsa"> <title> fdsa </ title> <Content > FASDF </ Content> <email> fsadfa </ email> </ message> </ messages> 2, operate XML program / ** * myjdom.java ** / package com.test; import org.jdom. *; import org.jdom.input *;. import org.jdom.output *;. import java.io.FileInputStream; import java.io.FileOutputStream; import java.util.List; public class MyJDom {public static void main (String [ ] args) throws exception {saxbuilder sb = new saxbuilder (); // Establish constructor Document Doc = Sb.Build (New FileInputStream ("c: //abc.xml")); // Read Specify file Element root = Doc.getrootElement (); // Get root node list = root.getchildren (); // put all child nodes under the root node in the list for for (int i = 0; i <list.size (); i ) {System.out.println ("-----------------------"); Element item = (element) list.get (i); // acquire the node instance String name = item.getattribute ("name"). getValue (); // acquisition attribute value system.out.println ("name ->" name); element sub = ITEM .Getchild ("Title"); // Take the word point String text = sub.gettext (); // get the value of the current node system.out.println ("Title ->" Text); ELEMENT Sub2 = item.getchild ("content"); string text2 = sub2.gettext (); system.out.println ("Content ->" text2; element sub3 =</p> <p>Item.Getchild ("email"); string text3 = sub3.gettext (); system.out.println ("email ->" text3);}}} Corenwang [original] Author Blog:</p> <p>http://blog.9cbs.net/corenwang/</p></div><div class="text-center mt-3 text-grey"> 转载请注明原文地址:https://www.9cbs.com/read-120878.html</div><div class="plugin d-flex justify-content-center mt-3"></div><hr><div class="row"><div class="col-lg-12 text-muted mt-2"><i class="icon-tags mr-2"></i><span class="badge border border-secondary mr-2"><h2 class="h6 mb-0 small"><a class="text-secondary" href="tag-2.html">9cbs</a></h2></span></div></div></div></div><div class="card card-postlist border-white shadow"><div class="card-body"><div class="card-title"><div class="d-flex justify-content-between"><div><b>New Post</b>(<span class="posts">0</span>) </div><div></div></div></div><ul class="postlist list-unstyled"> </ul></div></div><div class="d-none threadlist"><input type="checkbox" name="modtid" value="120878" checked /></div></div></div></div></div><footer class="text-muted small bg-dark py-4 mt-3" id="footer"><div class="container"><div class="row"><div class="col">CopyRight © 2020 All Rights Reserved </div><div class="col text-right">Processed: <b>0.042</b>, SQL: <b>9</b></div></div></div></footer><script src="./lang/en-us/lang.js?2.2.0"></script><script src="view/js/jquery.min.js?2.2.0"></script><script src="view/js/popper.min.js?2.2.0"></script><script src="view/js/bootstrap.min.js?2.2.0"></script><script src="view/js/xiuno.js?2.2.0"></script><script src="view/js/bootstrap-plugin.js?2.2.0"></script><script src="view/js/async.min.js?2.2.0"></script><script src="view/js/form.js?2.2.0"></script><script> var debug = DEBUG = 0; var url_rewrite_on = 1; var url_path = './'; var forumarr = {"1":"Tech"}; var fid = 1; var uid = 0; var gid = 0; xn.options.water_image_url = 'view/img/water-small.png'; </script><script src="view/js/wellcms.js?2.2.0"></script><a class="scroll-to-top rounded" href="javascript:void(0);"><i class="icon-angle-up"></i></a><a class="scroll-to-bottom rounded" href="javascript:void(0);" style="display: inline;"><i class="icon-angle-down"></i></a></body></html><script> var forum_url = 'list-1.html'; var safe_token = 'GhR9Ci_2BNOsmFnCl9yTJqkwM05OOcDfaO_2BjmRDI6h9Dh_2Bumvzsn9ERBoPInebBam4tFOxDD2hoVbfVjkhibMr4Q_3D_3D'; var body = $('body'); body.on('submit', '#form', function() { var jthis = $(this); var jsubmit = jthis.find('#submit'); jthis.reset(); jsubmit.button('loading'); var postdata = jthis.serializeObject(); $.xpost(jthis.attr('action'), postdata, function(code, message) { if(code == 0) { location.reload(); } else { $.alert(message); jsubmit.button('reset'); } }); return false; }); function resize_image() { var jmessagelist = $('div.message'); var first_width = jmessagelist.width(); jmessagelist.each(function() { var jdiv = $(this); var maxwidth = jdiv.attr('isfirst') ?
