我输入了xml文件，其中声明了多个名称空间。为了使样式表能够处理带前缀的元素，我需要手动将输入xml的名称空间声明复制到样式表。
我的问题是：是否有更优雅的方式让样式表知道命名空间形成输入xml？换句话说，从输入xml继承那些名称空间声明。
编辑1 输入xml名为 content.xml：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

我想要的结果是实现的。输出不是问题。问题是每个输入文件可能包含不同的命名空间声明，因此对于我需要处理的每个新输入xml，我必须手动将命名空间声明从xml文件复制到xsl文件。
到目前为止，我手动输入了命名空间声明。但它们往往变得越来越多。
请原谅我可怜的英语！
