在 Oracle SOA XSL 转换中迭代游标

Question

我有一个基本的应用程序，我从数据库中获取贷款产品列表并显示给用户。我写了一个 xsl 转换文件，我在其中迭代结果集并将每一行添加为贷款产品。但是最后的List里面填满了同样的对象。

我的composite.xml:

GetLoanProductsBPEL 内容：

和 GetLoanProductsBPEL 组件内的 Transform1 文件内容：

在数据库中我有 3 个贷款产品：

但结果我得到了相同贷款产品的 3 个实例：

<env:Body>
    <inp1:GetLoanProductsResponse xmlns:inp1="http://xmlns.oracle.com/singleString">
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
        <inp1:LoanProduct>
            <inp1:Id>1</inp1:Id>
            <inp1:Name>Cash loan</inp1:Name>
            <inp1:MaxAmount>100000</inp1:MaxAmount>
            <inp1:InterestRate>12</inp1:InterestRate>
            <inp1:MaxPeriod>60</inp1:MaxPeriod>
        </inp1:LoanProduct>
    </inp1:GetLoanProductsResponse>
</env:Body>

当我查看 Flow Trace 时，我发现在 Invoke 中我得到了 3 条不同的记录，但在 Transform1 之后，相同的记录被写入了 3 次。

调用 1 跟踪：

转换后的回复输出：

Answer 1

快速回答，因为我是通过手机回复的。从 for-each 循环内的 select 属性中删除 /top:VMbLoanProductsCollection/top:VMbLoanProducts/。
