目前在很多工程中需要生成相关的XML文件和解析XML文件一、XML文件生成说明1、基本概念：XML叶子节点、树节点、父节点、层次结构叶子节点：主要是指说明的是这个节点中没有层次结构了，仅仅拥有节点属性和相关的节点数据树节点：主要是有树形分支结构父节点：主要是指树形结构中的某个层次的上一层的关系：例如：A/B/C C的父节点是B层次结构主要是说明XML树中对应的树型结构XML树型路径（从根节点算起包括数节点）XML文件 CRM@001.ctnbc-;20120706150135;38 CRM@001.ctnbc- CRM*0914# CRM-SERV.CB@001.ctnbc- 123456 0 9907102600000029166 101000010 08528395597 851 852 1 20120801000000 20991231000000 5 12345600 20120801000000 20991231000000 下边这个图就是XML的树形结构：二、生成XML方式《1》按照XML的树型接口。
形成相关的XML树型结构模版模版的格式如下 {MID} {UID} {CUST_ID} {PRODUCT_ID} {ACC_NBR} {ACCT_ID} {PARM_ID} {PARM_VALUE} <2>形成XML实例（XML字符串）用到的APImon.xml.imp.XMLBaseParse （XML生成器）mon.xml.imp.XMLBaseReader（XML解析器）mon.xml.template.engine.XmlTemplateContainer（XML模版引擎）mon.xml.template.engine.XmlTemplateEngine（XML模版引擎）生成XML需要引入下边的包三、生成XML实例XML实例模版 {MID} {UID} {CUST_ID} {ACCT_ID} {PARM_ID} XML生成程序/** Created on 2012-7-9** TODO To change the template for this generated file go to* Window - Preferences - Java - Code Style - Code Templates*/package xml.test;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import mon.util.ReadFile;import mon.xml.imp.XMLCommonParse;import mon.xml.template.engine.XmlTemplateContainer;/*** @author Administrator** TODO To change the template for this generated type comment go to* Window - Preferences - Java - Code Style - Code Templates*/public class textXMLParse {public static void main(String[] args) {try {textXMLParse t = new textXMLParse();t.createXML();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}private void createXML() throws Exception{List xmlLevelList = new ArrayList();//XML的树形层次结构xmlLevelList.add(0, "root/SgwQueryReq");xmlLevelList.add(1, "root/SgwQueryReq/DATA");xmlLevelList.add(2, "root/SgwQueryReq/DATA/Service_Information");xmlLevelList.add(3, "root/SgwQueryReq/DATA/Service_Information/Data_Information");xmlLevelList.add(4, "root/SgwQueryReq/DATA/Service_Information/Data_Information/Data_Table_Simple_Row");xmlLevelList.add(5, "root/SgwQueryReq/DATA/Service_Information/Data_Information/Data_Table_Simple_Row/SERV");xmlLevelList.add(6, "root/SgwQueryReq/DATA/Service_Information/Data_Information/Data_Table_Simple_Row/SERV/BASE");xmlLevelList.add(7, "root/SgwQueryReq/DATA/Service_Information/Data_Information/Data_Table_Simple_Row/SERV/SERV_ACCT");xmlLevelList.add(8, "root/SgwQueryReq/DATA/Service_Information/Data_Information/Data_Table_Simple_Row/SERV/SERV_PARAM");XMLCommonParse xmlParse = new XMLCommonParse();//设置XML层次结构xmlParse.setXMLLevelList(xmlLevelList);//XML生成引擎数据容器XmlTemplateContainer container = new XmlTemplateContainer();container.setXMLLevelList(xmlLevelList);//设置XML模版ReadFile fl = new ReadFile();String classDir = this.getClass().getResource("testxml.vm").getPath();// System.out.println(fl.getFileContent(classDir));container.setXMLReader(classDir);Map dataMap = new HashMap();//设置层次节点root/SgwQueryReq这个叶子节点 这里中的第一个0参数表示上边树形结构中的位置。
