如何在节点测试中选择本地名称

Question

我试图对节点businessEntity进行数字签名。我在转换中使用Xpath来引用此节点。

我的XPath表达式是：

ancestor-or-self::ns1:businessEntity[ 
    @businessKey = 'uddi:testSignedProviderlastime' 
] and not(ancestor-or-self::ns1:businessService) 
    and not(ancestor-or-self::ds:Signature) 

我想删除的命名空间前缀NS1的依赖。有没有办法可以做到这一点？或者有没有一种方法可以在我的表达式中指定名称空间URI。

我已经尝试用替换命名空间前缀ns1，但因使用“”前缀而出现错误。 赞赏修改这个表达式的任何帮助。

感谢， 索尼娅

以下是XML，我将这种改造过：

Answer 1

我想你想的：

ancestor-or-self::*[local-name() = 'businessEntity'] 

或者更精确：

ancestor-or-self::* 
    [local-name() = 'businessEntity' and namespace-uri() = 'urn:uddi-org:api_v3']
