Question

我希望为我的XML查询函数编写一个XPath查询。我遇到的一个问题主要是因为我之前对XML的知识缺乏了解，而且我已经被迫加入了它。

但是，假设我有一个带有以下XML输出的文本框，我如何从<State>的{{1}}中提取信息？请注意，<ShipmentOrigin>还有其他几个实例，因此对<State>进行全面搜索是行不通的，必须专注于<State> <State>内<ShipmentOrigin> 1}}。

Answer 1

答案取决于处理XPath的内容以及是否可以将名称空间绑定到前缀。

如果您可以将https://webservices.rrts.com/tracking/命名空间绑定到前缀（例如tr），则可以执行以下操作...

//tr:ShipmentOrigin/tr:State

如果您无法将名称空间绑定到前缀，则可以使用local-name() ...

//*[local-name()='ShipmentOrigin']/*[local-name()='State']

您可以/也应该使用namespace-uri()来确保您完全匹配您想要匹配的内容......

//*[namespace-uri()='https://webservices.rrts.com/tracking/' and local-name()='ShipmentOrigin']/*[namespace-uri()='https://webservices.rrts.com/tracking/' and local-name()='State']
