fusionchart不规则XML的正则解析及Dom4j解析

java方法

public static  ArrayList<String> getData(String in ,String name){
//in = in.replaceAll("\n","");
Pattern p = null;
try {
p = Pattern.compile(""+name+"\\s*=\\s*\\'\\w*\\S*\\s*\\'");//正则解析
} catch (Exception e) {
e.printStackTrace();
}
Matcher m = p.matcher(in);
ArrayList<String> list = new ArrayList<String>();	//用List方便一些
while(m.find()){
String s[] = m.group().split("'");
if(s.length<=1){
s = " ' ' ".split("'"); //处理没有数据的情况 避免数组越界
}
list.add(s[1]);
}
return list;

}

然后是导出数据到Excel的方法(写Excel用的是jxl JAR包)

public static  boolean expoertExcel(String res){//res便是传递给fusionchart的数据 如果是文件形式 可以通过输入流读取
ArrayList<String> capt = new ArrayList<String>();
ArrayList<String> seri = new ArrayList<String>();
ArrayList<String> setv = new ArrayList<String>();
ArrayList<String> name = new ArrayList<String>();
ArrayList<String> ysname = new ArrayList<String>();
capt = getData(res,"caption");
seri = getData(res,"seriesName");
setv = getData(res, "value");
name = getData(res, "name");
ArrayList<String> sw = getData(res, "xAxisName");
String xname = sw.get(0);
ysname = getData(res, "yAxisName");
// jxl写 Excel
File ex =  new File("C:\\test.xls");//web项目的路径乱糟糟 运行的时候跑到tomcat的bin目录去了 先这样搞一下
if(ex.exists()){
ex.delete();
}
try {
if(!ex.exists()){
ex.createNewFile();
}
} catch (Exception e) {
e.printStackTrace();
}
WritableWorkbook wk = null;
try {
wk = Workbook.createWorkbook(ex);
} catch (IOException e) {
e.printStackTrace();
}
WritableSheet sheet = null;
Label label = null;
Number num=null;
sheet = wk.createSheet(capt.get(0),0);
label = new Label(0,0,capt.get(0));
try {
sheet.addCell(label);
} catch (RowsExceededException e1) {
e1.printStackTrace();
} catch (WriteException e1) {
e1.printStackTrace();
}
int snum = seri.size();
int lnum = name.size();
int vnum = setv.size();
int[][] p = new int[lnum][vnum];
for(int i=0;i<snum;i++){
label = new Label(0,i,seri.get(i));
if(sheet != null){
try {
sheet.addCell(label);
} catch (Exception e) {
e.printStackTrace();
}
}
for(int j=i*lnum;j<(i+1)*lnum;j++){
num = new Number(j-i*lnum+1,i,Double.parseDouble(setv.get(j)));
try {
sheet.addCell(num);
} catch (RowsExceededException e) {
e.printStackTrace();
} catch (WriteException e) {
e.printStackTrace();
}
}
}
for(int i=0;i<lnum;i++){
label = new Label(i+1,snum,name.get(i)+xname);
try {
sheet.addCell(label);
} catch (Exception e) {
e.printStackTrace();
}
}
label = new Label(0,snum+1,"数据单位是："+ysname.get(0));
try {
sheet.addCell(label);
} catch (Exception e) {
e.printStackTrace();
}
try {
wk.write();
} catch (IOException e) {
e.printStackTrace();
}
try {
wk.close();
} catch (Exception e) {
e.printStackTrace();
}
if(ex.exists()){
System.out.println(ex.getPath());
System.out.println(ex.toURI());
return true;
}else{
return false;
}
}//暂时还没想到好的思路 这算是一种笨方法吧 继续积累知识，找到更好的解决方法

捣鼓了几天的Dom4j 是可以解析fusionchart的xml文件的 代码如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import jxl.Workbook;

import jxl.write.Number;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.io.SAXReader;

public class TestDom4j {

/**

*/
public static void main(String[] args) {
test();
}

public static void test(){
File file = new File("G:\\xml\\line.xml");
if(!file.exists()){
System.out.println("文件不存在");
return;
}
InputStream in = null;
try {
in = new FileInputStream(file);
} catch (Exception e) {
e.printStackTrace();
}
SAXReader read = new SAXReader();
Document document = null;
try {
document = read.read(in);
} catch (Exception e) {
e.printStackTrace();
}
String caption="";
List list = document.selectNodes("//chart/@caption");//获取caption属性值
Iterator it = list.iterator();
while (it.hasNext()) {
Attribute cap = (Attribute)it.next();
caption = cap.getValue();
}
System.out.println(caption);
ArrayList<String> labelarList = new ArrayList<String>();
List labellist = document.selectNodes("//category/@label");//获取lable属性值
Iterator itl = labellist.iterator();
while (itl.hasNext()) {
Attribute labelAttribute = (Attribute)itl.next();
labelarList.add(labelAttribute.getValue());
}
for(int i=0;i<labelarList.size();i++){
System.out.println(labelarList.get(i));//测试一下
}
ArrayList<String> dataArrayList = new ArrayList<String>();
List dataList = document.selectNodes("//dataset/@seriesName");//获取seriesName属性的值
Iterator itd = dataList.iterator();
while (itd.hasNext()) {
Attribute dataAttribute = (Attribute)itd.next();
dataArrayList.add(dataAttribute.getValue());
}
for(int i=0;i<dataArrayList.size();i++){
System.out.println(dataArrayList.get(i));//测试一下
}
ArrayList<String> valueArrayList = new ArrayList<String>();
List valueList = document.selectNodes("//set/@value");//获取value属性的值
Iterator itv = valueList.iterator();
while (itv.hasNext()) {

valueArrayList.add(valueAttribute.getValue());
}
for(int i=0;i<valueArrayList.size();i++){
System.out.println(valueArrayList.get(i));//测试一下
}
//需要的数据都取到了 下边就可以写到Excel里了
File xls = new File("G:\\test.xls");
if(xls.exists()){
xls.delete();
}
try {
xls.createNewFile();
WritableWorkbook work = Workbook.createWorkbook(xls);
WritableSheet sheet = work.createSheet(caption,2);
int x=0,y=0,z=0;
x = dataArrayList.size();
y = labelarList.size();
z = valueArrayList.size();
System.out.println(x+" "+y+" "+z);
for(int i=0;i<x;i++){
Label data = new Label(0,i,dataArrayList.get(i));
sheet.addCell(data);
for(int j=0;j<y;j++){
Double dou = Double.parseDouble(valueArrayList.get(i*y+j));//
Number val = new Number(j+1,i,dou);
sheet.addCell(val);
}
}
for(int i=0;i<y;i++){
Label label = new Label(i+1,x,labelarList.get(i));
sheet.addCell(label);
}
work.write();
work.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}

下边是解析的fusionchart的xml文件

需要说几句的是最开始学习dom4j写练习的时候一直在报错 费了些劲 原来简单的dom4j可不是就这一个jar包就能搞定的还要有 xerces.jar，jaxen-1.1.1.jar 后边写Excel又加上了 jxl.jar不然就会报各种各样的错误。
