从数据库表创建xml

Question

我有一个XML文件的示例。现在我想用我所拥有的sql表数据生成一个原始的xml。

示例XML看起来是这样的：

<?xml version="1.0"?> 
<EmployeeSet xmlns=" http://www.abc.com/Employee.xsd " xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
<DefaultDeptt xsi:nil="true"/> 
<Report> 
    <Report Title="Yearly" Number="S678"> 
     <Status>Current</Status> 
     <Deptt xsi:nil="true"/> 
     <Employee LastName="Name" FirstName="Simple" EMail="simple@organization.org" Login="simple"/> 
     <Location>Builiding 1</Location> 
     <SubmissionDate xsi:nil="true"/> 
     <ReportStartDate>2011-05-05</ReportStartDate> 
     <ReportFinishDate xsi:nil="true"/> 
     <ReportExpirationDate>2014-05-05</ReportExpirationDate> 
     <RenewalDate xsi:nil="true"/> 
     <Records> 
      <RecordsInfo Name="Paper"> 
      <UsageRecords AnnualUse="5o0" Purpose="printing"/> 
      </RecordInfo> 
     </Record> 
    <Staff/> 
</Report> 

表从我获取数据有如下结构：

• REPORT_TITLE
• 数
• 状态
• 姓氏
• first_nam Ë
• 电子邮件
• LOGIN_ID
• 位置
• submission_date
• 起始日期
• Finsih_date
• RENEWAL_DATE
• 名
• annual_use
• 目的

请帮我生成这个XML。这很紧急。

我想我的手和我得到以下几点：

`

<DefaultDeptt xsi:nil="true"></DefaultDeptt>   
<report_title>TESTINGNEW</report_TITLE>  
<NUMBER>AC10006</NUMBER>  
<STATUS>Approved</STATUS>  
<LAST_NAME>XYZ</LAST_NAME>  
<FIRST_NAME>ABC</PI_FIRST_NAME>  
<EMAIL>ABC.XYZ@gmail.com</EMAIL>  
<LOGIN_ID>ABCXYZ</LOGIN_ID>  
<LOCATION> </ LOCATION>  
                        <SUBMISSION_DATE>2013-03-25</SUBMISSION_DATE>             <START_DATE>2013-03-25</START_DATE>   
<FINISH_DATE>2013-03-25</FINISH_DATE>   
<RENEWAL_DATE>2014-01-9</RENEWAL_DATE>   
<NAME>PAPER</NAME>   
<ANNUAL_USE>670</ANNUAL_USE>  
<PURPOSE> PRINTING</PURPOSE>

我觉得这样的事情将是建在包在Oracle XMLDOM有益尝试谷歌

declare 
      xml_content CLOB:=null; 
      doc xmldom.domdocument; 
      main_node xmldom.DOMNode;                   
      root_node xmldom.DOMNode;                   
      root_elmt xmldom.DOMElement;                   
      transmissionHeaderNode xmldom.DOMNode;                
      transmissionHeaderElement xmldom.DOMElement;

      item_text xmldom.DOMText; 
      redx_elmt xmldom.DOMElement; 
begin 
      --some cursor 
      for c1 in (
         select * from (yourtable) 
         ) 
      loop

       doc := xmldom.newdomdocument;

       root_elmt := xmldom.createelement(doc, 'Some header') 
       root_node := xmldom.appendchild(main_node, xmldom.makenode(root_elmt));    
       transmissionheaderelement := xmldom.createelement(doc, 'XML_DOCUMENT'); 
       transmissionheadernode := xmldom.appendchild(root_node, xmldom.makenode(transmissionheaderelement)); 
     -- lets say in cursor you have location field 
       item_elmt := xmldom.createelement(doc, 'Location'); 
       item_node := xmldom.appendchild(transmissionheadernode, xmldom.makenode(item_elmt));     
       item_text := xmldom.createTextNode(doc, c1.Location);        
       item_node := xmldom.appendchild(item_node, xmldom.makenode(item_text)); 
      . 
      . 
      . 
      -- before end of loop 
       dbms_lob.createtemporary(xml_content, true, dbms_lob.call); 
       xmldom.writetoclob(doc, xml_content);    
       xmldom.freedocument(doc);    


    end loop;
