复制代码 代码如下:

function getTableDataByXML(inTable, inWindow) {
    var rows = 0;
    //alert("getTblData is " + inWindow);
    var tblDocument = document;
    if (!!inWindow && inWindow != "") {
        if (!document.all(inWindow)) {
            return null;
        }
        else {
            tblDocument = eval(inWindow).document;
        }
    }
    var inTbl = tblDocument.getElementById(inTable);
    var outStr = "<?xml version="1.0"?>n";
    outStr = outStr + "<?mso-application progid="Excel.Sheet"?>n";
    outStr = outStr + "<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"";
    outStr = outStr + " xmlns:o="urn:schemas-microsoft-com:office:office"";
    outStr = outStr + " xmlns:x="urn:schemas-microsoft-com:office:excel"";
    outStr = outStr + " xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">n";
    outStr = outStr + "<Worksheet ss:Name="Sheet1">n";
    outStr = outStr + "<Table ss:ExpandedColumnCount="30">n";
    var re = /^[0-9]+.?[0-9]*$/; //是否为数字
    if (inTbl != null) {
        for (var j = 0; j < inTbl.rows.length; j++) {
            outStr += "<Row ss:AutoFitHeight="0">n";
            for (var i = 0; i < inTbl.rows[j].cells.length; i++) {
                if (i == 0 && rows > 0) {
                    outStr += "<Cell><Data ss:Type="String"></Data></Cell>n";
                    rows -= 1;
                }
                var cellValue = inTbl.rows[j].cells[i].innerText;
                //小于12位数字用Number
                if(re.test(cellValue) && (new String(cellValue)).length < 11){
                    outStr = outStr + "<Cell><Data ss:Type="Number">" + cellValue + "</Data></Cell>n";
                }else{
                    outStr = outStr + "<Cell><Data ss:Type="String">" + cellValue + "</Data></Cell>n";
                }
                if (inTbl.rows[j].cells[i].colSpan > 1) {
                    for (var k = 0; k < inTbl.rows[j].cells[i].colSpan - 1; k++) {
                        outStr += " <Cell><Data ss:Type="String"></Data></Cell>n";
                    }
                }
                if (i == 0) {
                    if (rows == 0 && inTbl.rows[j].cells[i].rowSpan > 1) {
                        rows = inTbl.rows[j].cells[i].rowSpan - 1;
                    }
                }
            }
            outStr += "</Row>n";
        }
    }
    else {
        outStr = null;
        alert("你要导出的表不存在!!");
        return;
    }
    outStr = outStr + "</Table>n</Worksheet>n</Workbook>";
    return outStr;
}

上述函数原本是导出txt文件的函数。把excel文件另存为一个xml文件,就可得到excel能识别什么内容格式的xml文件。
