请不要只要求我们为您解决问题。向我们展示你是如何试图自己解决问题的，然后向我们展示结果是什么，并告诉我们为什么你觉得它不起作用。请参阅“”，这是一篇您确实需要阅读的优秀文章。在本例中，作者每行解析文本行，并使用substring after和substring before可能会有所帮助。我在一篇不相关的文章中发现，XSLT既不处理“detect&format”，也不直接处理XML。最好的解决方案似乎是使用javascript函数之类的东西处理源XML文件。我想我期待XSLT成为XML的灵丹妙药。@Pres，关于你最后的评论：看来你还没有读到我的答案：）@Dimitre。非常感谢你的回答。我不在家，我认为这一评论是在你作出深入回应之前发表的。我刚刚看到了这一点，所以将在第一个可能的机会阅读。感谢您提供如此明确的答案。我只使用了XSLT v1，因此必须尽快深入研究v2，如果您想要更精确的正则表达式，这里有一个：，尽管它非常长，并且不能保证它不会破坏一些正则表达式引擎。（还有一个变体位于./TypeLibrary-IRI-RFC3987.xsd）@MichaelKay，谢谢。一个相关的问题——为什么不能使用

xs:anyUri

验证？我尝试将

castable设置为

和

实例

——结果就像我指定了

xs:string

基本上，XSD在URI的定义上陷入了混乱。有太多的定义：绝对URI、相对URI、遗留URI（leiris）、“wannabe URI”（在%-编码后的URI字符串）URI符合通用语法，但不符合
