Usando o XSLT para comparar dois nós e emitir XML contendo atributo indicando se o valor foi atualizado, adicionado ou excluído

Question

Estou programando idiomas front-end há muito tempo e raramente encontro XSLT em um projeto. Bem, aqui está ... atualmente temos algumas funções em nosso arquivo XSLT que estão comparando nós e emitindo XML que contém algo como previousValue="Old value". Esse recurso ajuda nossos usuários a entender o que mudou ao visualizar o formulário.

Olhando para o XML (abaixo), preciso comparar <ns1:OtherEducationTypeDesc> e emite XML corretamente que afirma qual era o valor antigo.

Eu preciso que isso pareça algo como:

<EducationTypes>
    <EducationType Code="11">Engineering</EducationType>
    <EducationType Code="12" Value="New Value" PrevValue="Old Value">Other</EducationType>
</EducationTypes>

Tentei fornecer o máximo de informações possível, mas se você precisar de mais alguma coisa, me avise! Qualquer assistência é apreciada !! Obrigado!!

Answer 1

possibilidades:

.

1. Adicione um redirecionamento de javascript em uma peça de editor de conteúdo nas páginas que deseja ser redirecionada.

2. Edite a página mestra atualmente em uso e crie uma função JavaScript para redirecionar o usuário de acordo com a URL atual.

   Mas se você tiver ISA ou TMG, implementar uma regra lá para lidar com o redirecionamento.
