长期从事前端语言编程,XSLT
在项目中很少遇到。好吧,就是这样……我们目前在 XSLT 文件中有一些函数,它们用于比较节点并发出包含类似previousValue="Old value"
. 此功能可帮助我们的用户了解查看表单时发生的变化。
查看 XML(如下),我需要<ns1:OtherEducationTypeDesc>
正确比较和发出 XML,说明旧值是什么。
我需要它看起来像:
<EducationTypes>
<EducationType Code="11">Engineering</EducationType>
<EducationType Code="12" Value="New Value" PrevValue="Old Value">Other</EducationType>
</EducationTypes>
我试图提供尽可能多的信息,但如果您需要任何其他信息,请告诉我!任何帮助表示赞赏!谢谢!!
