1.xml字符串
/*

<order>
<orderid>1</orderid>
<ordernumber>857544544</ordernumber>
<orderprice>54</orderprice>
</order>

<orderid>2</orderid>
<ordernumber>858544544</ordernumber>
<orderprice>63</orderprice>

<order>
<orderid>3</orderid>
<ordernumber>454854555</ordernumber>
<orderprice>781</orderprice>

2.oracle存储过程

r_cur OUT SYS_REFCURSOR)
AS

***/

BEGIN

-- 释放解析器实例

-- 所有属性
temparrmap := xmldom.getattributes (tempnode);
-- 获取子元素的值
chilnodes := xmldom.getchildnodes (tempnode);
tmp := xmldom.getlength (chilnodes);
l_sql := l_sql || materialid || ' as materialid';
FOR i IN 0 .. tmp - 1
LOOP

OPEN r_cur FOR l_sql;
-- 释放文档对象

EXCEPTION
WHEN OTHERS
THEN
