我使用了一个工具来映射这个 xquery,但需要了解该工具在幕后做了什么,以避免自己成为该工具的奴隶
(:: pragma bea:global-element-parameter parameter="$retrieveCustomerByCriteriaResponse1" element="ns0:RetrieveCustomerByCriteriaResponse" location="../wsdl/CustomerService.wsdl" ::)
(:: pragma bea:global-element-return element="ns3:FindCustomerResponse" location="../wsdl/CustomerManagement.wsdl" ::)
declare namespace ns2 = "http://www.somecorp.com/customer";
declare namespace ns1 = "http://www.somecorp.com/creditcard";
declare namespace ns3 = "http://www.somecorp.org/CustomerManagement";
declare namespace ns0 = "http://www.crm.org/CustomerService/";
declare namespace xf = "http://tempuri.org/basic-osb-service/transformation/TransformFindCustomerResponse/";
declare function xf:TransformFindCustomerResponse(**$retrieveCustomerByCriteriaResponse1 as element(ns0:RetrieveCustomerByCriteriaResponse**))
as element(ns3:FindCustomerResponse) {
<ns3:FindCustomerResponse>
<Customer>
<ns2:ID>{ xs:long($retrieveCustomerByCriteriaResponse1/customers/id) }</ns2:ID>
<ns2:FirstName>{ data($retrieveCustomerByCriteriaResponse1/customers/firstname) }</ns2:FirstName>
<ns2:LastName>{ data($retrieveCustomerByCriteriaResponse1/customers/lastname) }</ns2:LastName>
<ns2:EmailAddress>{ data($retrieveCustomerByCriteriaResponse1/customers/emailAddress) }</ns2:EmailAddress>
<ns2:Addresses>
{
let $address := $retrieveCustomerByCriteriaResponse1/customers/address
return
<ns2:Address>
<ns2:Street>{ data($address/street) }</ns2:Street>
<ns2:PostalCode>{ data($address/zipcode) }</ns2:PostalCode>
<ns2:City>{ data($address/city) }</ns2:City>
</ns2:Address>
}
</ns2:Addresses>
<ns2:Rating>{ data($retrieveCustomerByCriteriaResponse1/customers/rating) }</ns2:Rating>
<ns2:Gender>{ data($retrieveCustomerByCriteriaResponse1/customers/gender) }</ns2:Gender>
</Customer>
</ns3:FindCustomerResponse>
};
declare variable $retrieveCustomerByCriteriaResponse1 as element(ns0:RetrieveCustomerByCriteriaResponse) external;
xf:TransformFindCustomerResponse($retrieveCustomerByCriteriaResponse1)
有人可以解释一下这段代码的作用吗?这个函数的输入参数是什么?
