使用Java将字符串转换为XML

我从PDF中提取了如下字符串格式的数据（请注意间距不均和新行字符）

如何将此字符串转换为XML，如下所示

public void testMethod()
    {
        String extractedTestFromPDF=
                 " Virtual Salary                                 25,100.00   EIS EE Contr.                                       7.90\n"+
                 "\t Virtual Car Allowance                           1,600.00   EPF Employee Contr.                             2,937.00\n"+
                 " Payment Received(Oversea)                       4,265.01   SOCSO Employee Contr.                              19.75\n";

    }

Desire XML：

<xml>
<Data>
    <Allowance>Virtual Salary</Allowance>
    <Allowance_Amount>25,100.00</Allowance_Amount>
</Data>
<Data>
    <Allowance>EIS EE Contr.</Allowance>
    <Allowance_Amount>7.90</Allowance_Amount>
</Data>
<Data>
    <Allowance>Virtual Car Allowance</Allowance>
    <Allowance_Amount>1,600.00</Allowance_Amount>
</Data>
...
</xml>

虚拟工资
25,100.00
环境影响报告书。
7.90
虚拟汽车津贴
1,600.00
...

谢谢你，艾根。如果您能在Java7中发布上述方法，我们将非常感谢，因为我们仍然使用旧版本。
