执行XSLT转换时的XPath问题

Question

我被这个问题困了2天。我只想提取图像中标记的数据，以便通过XSLT进行转换。我在这个问题中也给出了XML文件。抱歉，如果这是一个非常愚蠢的问题。类似的路径，如//partyinformation/buyer/contact//name在文档中工作。但是//partyinformation/买主/联系人//姓名不起作用

到目前为止我已经试过了，

• //partyinformation/buyer/contact/name1
• //partyinformation/买家/联系人//姓名
• /Invoice[@xmlns:xsd=“http://www.w3.org/2001/xmlschema”]/partyinformation[@xmlns=“”]/buyer/contact[@xmlns=“http://companydomain.schema”]/name[@xmlns=“”]/text()

Answer 1

这是因为Contact节点位于http://companydomain.schema命名空间下。尝试：

//PartyInformation/Buyer/*[local-name()='Contact']/Name

或者，您可以在xslt中注册命名空间，

xmlns:com="http://Companydomain.Schema"

并拥有xpath

//PartyInformation/Buyer/com:Contact/Name
