如何使用XSLT將XML轉換爲文本文件

Question

我想使用XSLT將XML文件轉換爲文本，但我沒有任何使用XSLT的經驗。

下面是一個示例XML文件：

<DOC xsi:noNamespaceSchemaLocation="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
<DOC_REQUISITES DOC_DATE="2009-04-23" DOC_NO="99999999"/> 
<DOCID TradeDate="2009-04-23" Weekday="Monday" MainFirmId="ZXC0000" FirmName="Firm Name" FirmINN="1234567899"> 
    <FIRM FirmID="FirmId"> 
    <CURRENCY CurrencyId="USD"> 
    <DEPARTMENT DepartmentId="ABCD" DepName="Department Name1"> 
    <SETTLEDATE SettleDate="2009-04-23"> 
     <SECURITY SecurityId="QAZ" SecShortName="SecName1" SecurityType="dc" FaceValue="5"> 
     <TRDACC TrdAccId="ABC00000"> 
     <RECORDS RecNo="1" TradeNo="111" TradeTime="15:15:16" Price="10" Quantity="50" Value="500"/> 
     </TRDACC> 
     <TRDACC TrdAccId="SDC00000"> 
     <RECORDS RecNo="2" TradeNo="112" TradeTime="15:15:16" Price="10" Quantity="50" Value="500"/> 
     <RECORDS RecNo="3" TradeNo="113" TradeTime="15:15:16" Price="20" Quantity="10" Value="200"/> 
     </TRDACC> 
     </SECURITY> 
     <SECURITY SecurityId="WSX" SecShortName="SecName2" SecurityType="dc" FaceValue="1"> 
     <TRDACC TrdAccId="ABC00000"> 
     <RECORDS RecNo="4" TradeNo="114" TradeTime="15:15:13" Price="2" Quantity="1" Value="2"/> 
     </TRDACC> 
     </SECURITY> 
    </SETTLEDATE> 
    </DEPARTMENT> 
    <DEPARTMENT DepartmentId="CBSD" DepName="Department Name2"> 
    <SETTLEDATE SettleDate="2009-05-20"> 
     <SECURITY SecurityId="RFV" SecShortName="SecName3" SecurityType="dc" FaceValue="2"> 
     <TRDACC TrdAccId="SDC00000"> 
     <RECORDS RecNo="5" TradeNo="115" TradeTime="15:15:13" Price="100" Quantity="10" Value="1000"/> 
     </TRDACC> 
     </SECURITY> 
    </SETTLEDATE> 
    </DEPARTMENT> 
    </CURRENCY> 
    </FIRM> 
</DOCID> 
</DOC> 

我期望的輸出是這樣的：

2009-04-23,99999999,2009-04-23,Monday,ZXC0000,Firm Name,1234567899,FirmId,USD,ABCD,Department Name1,2009-04-23,QAZ,SecName1,dc,5,ABC00000,1,111,15:15:16,10,50,500 
2009-04-23,99999999,2009-04-23,Monday,ZXC0000,Firm Name,1234567899,FirmId,USD,ABCD,Department Name1,2009-04-23,QAZ,SecName1,dc,5,SDC00000,2,112,15:15:16,10,50,500 
2009-04-23,99999999,2009-04-23,Monday,ZXC0000,Firm Name,1234567899,FirmId,USD,ABCD,Department Name1,2009-04-23,QAZ,SecName1,dc,5,SDC00000,3,113,15:15:16,20,10,200 
2009-04-23,99999999,2009-04-23,Monday,ZXC0000,Firm Name,1234567899,FirmId,USD,ABCD,Department Name1,2009-04-23,WSX,SecName2,dc,1,ABC00000,4,114,15:15:13,2,1,2 
2009-04-23,99999999,2009-04-23,Monday,ZXC0000,Firm Name,1234567899,FirmId,USD,CBSD,Department Name2,2009-05-20,RFV,SecName3,dc,2,SDC00000,5,115,15:15:13,100,10,1000
