oracle 如何从多个同名节点中检查一个值，然后使用

我正在尝试从this XML table中提取值
我需要首先检查FreeCode节点中的ID是否为pTRAFC50。如果它确实是pTRAFC50，那么我将从FreeCode内的Value子节点中提取值。
我试着用[7]，但它不起作用

case when EXTRACTVALUE(XmlType(o.Xml), '/Equity/FreeCode[7]/@ID[7]') = 'pTRAFC50'
case when EXTRACTVALUE(XmlType(o.Xml), '/Equity/FreeCode[7]/@ID[7]') = 'pTRAFC50'

字符串
如果节点是“pTRAFC50”，我希望能够将NA拉到我的提取中。

试试这个模式：

/Equity/FreeCode[@ID = 'pTRAFC50']/@Value
