我们有一个需求，我们需要为一个节点获取一个字符串形式的 XML 有效负载，我们需要扩展这个 XML 并将 XML 节点值传递给目标 XSD 列。

例如输入 XSD：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Transaction xmlns="http://xmlns.oracle.com/2012/SCEM">
    <TRXKEY>0x0000013</TRXKEY>
    <EVENTNAME>SalesOrder</EVENTNAME>
    <ACCEPTEDQUANTITY>0</ACCEPTEDQUANTITY>
    <ORDEREDQUANTITY>0</ORDEREDQUANTITY>
    <SOLORGID>0</SOLORGID>
    <LHORDERHOLDIDRELEASED>0</LHORDERHOLDIDRELEASED>
    <ORDEREDQUANTITYUOM>0</ORDEREDQUANTITYUOM>
    <UNITSELLINGPRICE>0</UNITSELLINGPRICE>
    <ORDERTYPE>&lt;Val lang='AR'&gt;OrderTypeARARARAR&lt;/Val&gt;
                    &lt;Val lang='KO'&gt;OrderTypeKOKOKOKO&lt;/Val&gt;
                    &lt;Val lang='US'&gt;OrderTypeUSUSUUS&lt;/Val&gt;
                   </ORDERTYPE>
</Transaction>

输出 XML

<Transaction1 xmlns="http://xmlns.oracle.com/2012/SCEM">
    <TRXKEY>0x0000013</TRXKEY>
    <EVENTNAME>SalesOrder</EVENTNAME>
    <ACCEPTEDQUANTITY>0</ACCEPTEDQUANTITY>
    <ORDEREDQUANTITY>0</ORDEREDQUANTITY>
    <SOLORGID>0</SOLORGID>
    <LHORDERHOLDIDRELEASED>0</LHORDERHOLDIDRELEASED>
    <ORDEREDQUANTITYUOM>0</ORDEREDQUANTITYUOM>
    <UNITSELLINGPRICE>0</UNITSELLINGPRICE>
    <ORDERTYPE_AR>OrderTypeARARARAR</ORDERTYPE_AR>
    <ORDERTYPE_US>OrderTypeUSUSUUS</ORDERTYPE_US>
    <ORDERTYPE_KO>OrderTypeKOKOKOKO</ORDERTYPE_KO>
</Transaction>

我们需要遍历 ORDERTYPE 节点 XML 字符串。根据 'Val lang=' 值，我们需要将此节点值传递给输出 XSD ORDERTYPE_$lang 值列。

我如何遍历这两个不同值的 XML 字符串并将其传递给相应的输出 XML 列？

我正在考虑使用拆分，但它没有多大帮助。
