* 首先创建一个32313133353236313431303231363533e59b9ee7ad9431333337373665XML文档

* 要创建XML文档，首先创建一个根元素

Element reportRoot=new Element("sheet");

Document xmlReport=new Document(reportRoot);

try {

//读取Excel文件

FileInputStream excelFIS=new FileInputStream("D:\JavaTest\Employee_List.xls");

//创建Excel工作表

HSSFWorkbook excelWB=new HSSFWorkbook(excelFIS);

//获得Excel工作簿

HSSFSheet excelSheet=excelWB.getSheetAt(0);

//获得工作簿的行数

int rows=excelSheet.getPhysicalNumberOfRows();

//遍历工作簿的行

for(int rowIndex=0; rowIndex

HSSFRow oneRow=excelSheet.getRow(rowIndex);

if(oneRow==null){

continue;

}

//在迭代每一行的时候，创建xml的行元素

Element rowElement=new Element("row");

//获得当前行的单元格数

int cells=oneRow.getPhysicalNumberOfCells();

//遍历行中的每一个单元格

for(int cellIndex=0;cellIndex

HSSFCell oneCell=oneRow.getCell(cellIndex);

if(oneCell==null){

continue;

}

//设置元素的默认名称

String elementName="header";

//获得单元格所在列位置

int cellColumnIndex=oneCell.getColumnIndex();

if(rowIndex>0){

elementName=reportRoot.getFirstChildElement("row").getChild(cellColumnIndex).getValue();

}

* 去掉非法字符

elementName = elementName.replaceAll("[\P{ASCII}]","");

elementName = elementName.replaceAll(" ", "");

Element cellElement = new Element(elementName);

//添加属性和元素

//String attributeValue=oneCell.getCellStyle().getDataFormatString();

//Attribute dataFormatAttribute=new Attribute("dataFormat", attributeValue);

//cellElement.addAttribute(dataFormatAttribute);

* 根据不同的属性添加

Attribute strTypeAttribute=null;

switch (oneCell.getCellType()) {

case HSSFCell.CELL_TYPE_STRING:

strTypeAttribute=new Attribute("dataType","String");

cellElement.addAttribute(strTypeAttribute);

cellElement.appendChild(oneCell.getStringCellValue());

rowElement.appendChild(cellElement);

break;

case HSSFCell.CELL_TYPE_NUMERIC:

strTypeAttribute=new Attribute("dataType","Numeric");

cellElement.addAttribute(strTypeAttribute);

HSSFDataFormatter dataFormatter=new HSSFDataFormatter();

String cellFormatted=dataFormatter.formatCellValue(oneCell);

cellElement.appendChild(cellFormatted);

rowElement.appendChild(cellElement);

break;

}

if(rowElement.getChildCount()>0){

reportRoot.appendChild(rowElement);

}

//System.out.println(xmlReport.toXML());

}
