XSLT：重复输入n次，复制输入，但根据传递的参数更改某些属性
我是XSLT初学者，需要一些帮助（XSLT1.0）。 基本上，我需要重复输入给定的次数，复制它，但改变一些属性的值 我已经看到，实现这一点的“标准方法”是使用apply-templates和xsl:copy，但问题是我需要根据从“上层”传递的参数更改这些属性的值，所以我认为我需要使用call-template，但我就是想不出这一点：） 输入：XSLT：重复输入n次，复制输入，但根据传递的参数更改某些属性,xslt,xslt-1.0,Xslt,Xslt 1.0,我是XSLT初学者，需要一些帮助（XSLT1.0）。 基本上，我需要重复输入给定的次数，复制它，但改变一些属性的值 我已经看到，实现这一点的“标准方法”是使用apply-templates和xsl:copy，但问题是我需要根据从“上层”传递的参数更改这些属性的值，所以我认为我需要使用call-template，但我就是想不出这一点：） 输入： <Repeater repeatCount="3"> <!-- Only one direct child of Repeater

这里是另一个选项。如果您需要添加进一步的转换，那么它不像Michael的答案那么清晰，但它非常简单 XML输入
