XPath запросов на Spring контексте Фасоль Application

Question

с помощью Xpath запроса я хотел бы получить эти 2 элемента

<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="always" 
         entry-point-ref="authenticationEntryPoint"> 
      <security:custom-filter ref="covAuthFilter" position="FORM_LOGIN_FILTER"/> 

из этой весной конфигурационный файл

Я попытался следующие:

//s:beans//security:http[1] 

//security:http[1] 

до нет ail, tnx. Я буду использовать это на maven-config-processor-plugin и вставить что-то динамически в конфигурацию пружины во время пакета или установки.

Answer 1

при использовании пространств имен в XPath пространство имен должно быть определено в контексте, который вы используете в xapth в

, если это не возможно, вы могли бы использовать подстановочные так:.

//*:http[1] 

- редактировать -

я только что видел, что Maven плагин вы используете allows to define пространства имен контексты. я полагаю, вы могли бы использовать это, чтобы определить пространства имен, которые вы используете в своем xpath, вместо того, чтобы полагаться на подстановочные знаки.
