通过使用XPath从WSDL文件中导入的(“xsd:import”)模式获取XML元素声明

通过使用XPath从WSDL文件中导入的(“xsd:import”)模式获取XML元素声明,xml,xpath,wsdl,xsd,Xml,Xpath,Wsdl,Xsd,我有个问题已经困扰了我一周了 我使用Netbeans 7.2.1将虚拟web服务编程为无状态EJB: @WebService(serviceName = "WSPersonLookup") @Stateless() public class WSPersonData { @PersistenceContext(unitName="PUWSPersonData") private EntityManager em; /** * Web service operation */

我有个问题已经困扰了我一周了

我使用Netbeans 7.2.1将虚拟web服务编程为无状态EJB:

@WebService(serviceName = "WSPersonLookup")
@Stateless()
public class WSPersonData {

  @PersistenceContext(unitName="PUWSPersonData")
  private EntityManager em;

 /**
  * Web service operation
  */
  @WebMethod(operationName = "getPersonData")
  public Person getPersonData(@WebParam(name = "personId") final String personId) {
    return em.find(Person.class, personId);
  }
}
类“Person”只是映射到此表的JPA实体(我使用PostgreSQL作为DBMS):

产生的WSDL如下所示:

      <soap:address location="http://pc-i2b:8080/WSPersonLookup/WSPersonData" />
    </port>
  </service>
</definitions>

XSD声明:

<?xml version='1.0' encoding='UTF-8'?>

      <xs:element name="phone" type="xs:int"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

问题是:我需要访问上面在WSDL中导入的模式声明:

 <types>
    <xsd:schema>
      <xsd:import namespace="http://ws.i2b.com/" schemaLocation="http://pc-i2b:8080/WSPersonLookup/WSPersonData?xsd=1" />
    </xsd:schema>
  </types>

通过使用XPath。我不允许直接访问模式

有办法吗?如果没有,有人知道这方面的解决方法吗


问候。

您不能仅使用XPath获取主XML文档(WSDL)引用的辅助XML文档(本例中的模式)

使用XSLT,您可以使用
document()
函数:

<xsl:variable name="schema" select="document(/soap:definitions/soap:types/xsd:schema/xsd:import/@schemaLocation)"/>

或者,与其尝试获取导入的模式,不如使用类似于
/soap:definitions/soap:types/xsd:schema
的XPath获取WSDL中的模式片段。这是一个有效的架构,正在导入
http://pc-i2b:8080/WSPersonLookup/WSPersonData?xsd=1
-您应该能够直接使用它

<xsl:variable name="schema" select="document(/soap:definitions/soap:types/xsd:schema/xsd:import/@schemaLocation)"/>
