XSLT заменить атрибуты

Question

У меня есть следующий XML

<ExternalAssessmentRequest> 
    <ApplicationData Lender="Test"> 
     <LiabilityList> 
      <RequestedLoan Identifier="New1" BaseAmount="250000" LoanAccountFees="100" LoanAccountLMI="2000" LoanTerm="25" LoanTermMonths="6" Product="Basic Variable" Repurposing="No" PrimaryPurpose="OwnerOccupied" TaxDeductible="No" InterestRate="0.075" ProductID="Product1" PaymentType="InterestOnly" ABSCode="123"> 
       <Applicant RelatedIdentifier="Applicant1" Percentage="0.5"/> 
       <Applicant RelatedIdentifier="Applicant2" Percentage="0.5"/> 
       <Feature Code="SupaPackage"/> 
      </RequestedLoan> 
     </LiabilityList> 
    </ApplicationData> 
    <AdditionalAssessment Lender="MegaBank"> 
     <RequestedLoan Product="Supa Variable" ProductID="Product2"/> 
    </AdditionalAssessment> 
</ExternalAssessmentRequest> 

мне нужно использовать Xpath, чтобы создать два отдельных элемента. Один из них - существующий, а другой - уже существующий, но только те элементы и атрибуты, которые указаны в нем, должны быть заменены.

Таким образом, конечный результат должен быть

<ExternalAssessmentRequest> 
    <ApplicationData Lender="Test"> 
     <LiabilityList> 
      <RequestedLoan Identifier="New1" BaseAmount="250000" LoanAccountFees="100" LoanAccountLMI="2000" LoanTerm="25" LoanTermMonths="6" Product="Basic Variable" Repurposing="No" PrimaryPurpose="OwnerOccupied" TaxDeductible="No" InterestRate="0.075" ProductID="Product1" PaymentType="InterestOnly" ABSCode="123"> 
       <Applicant RelatedIdentifier="Applicant1" Percentage="0.5"/> 
       <Applicant RelatedIdentifier="Applicant2" Percentage="0.5"/> 
       <Feature Code="SupaPackage"/> 
      </RequestedLoan> 
     </LiabilityList> 
    </ApplicationData> 
    <ApplicationData Lender="MegaBank"> 
     <LiabilityList> 
      <RequestedLoan Identifier="New1" BaseAmount="250000" LoanAccountFees="100" LoanAccountLMI="2000" LoanTerm="25" LoanTermMonths="6" Product="Supa Variable" Repurposing="No" PrimaryPurpose="OwnerOccupied" TaxDeductible="No" InterestRate="0.075" ProductID="Product2" PaymentType="InterestOnly" ABSCode="123"> 
       <Applicant RelatedIdentifier="Applicant1" Percentage="0.5"/> 
       <Applicant RelatedIdentifier="Applicant2" Percentage="0.5"/> 
       <Feature Code="SupaPackage"/> 
      </RequestedLoan> 
     </LiabilityList> 
    </ApplicationData> 
</ExternalAssessmentRequest> 

Pleaseeee помочь мне.

Этот ответ адреса изначально неявном требование наличия ряда произвольно названных дочерних элементов <LiabilityList>:

Answer 2

Ответ основан на знании того, что вы можете переопределить значение атрибута элемента сколько угодно раз, прежде чем начинать добавлять содержимое элемента. В моем решении я копирую атрибуты данных, а затем просто копирую их с дополнительными атрибутами.

t:\ftemp>type attrs.xml 
<ExternalAssessmentRequest> 
    <ApplicationData Lender="Test"> 
     <LiabilityList> 
      <RequestedLoan Identifier="New1" BaseAmount="250000" LoanAccountFees="100" LoanAccountLMI="2000" LoanTerm="25" LoanTermMonths="6" Product="Basic Variable" Repurposing="No" PrimaryPurpose="OwnerOccupied" TaxDeductible="No" InterestRate="0.075" ProductID="Product1" PaymentType="InterestOnly" ABSCode="123">

     </LiabilityList>
