使用XML获取当前日期
使用XML获取当前日期
提问于 2011-11-10 03:34:24
我在一个XML类中，拥有这部分额外的信用。
我们正在测试一个类被添加到一个时间表中的日期，以确保它是在1964年9月1日或之后，或者在今天的日期之前或之后。

</Courses>dateAdded字段是正在测试的字段。通过使用DateAdded >= 9/1/1964和DateAdded <=来测试1964年的日期，我们将使用maxInclusive来处理今天的日期，但是我们被告知使用DTD来操作模式。是的，这是愚蠢的做法，但既然可以做到，教练希望我们这样做。
但是，他还没有研究如何通过使用DTD文件的XSLT文件来验证XML文件。我们使用DTD完成了XML，用XSLT完成了XML，但这三种方法都没有完成。

在XSD1.0中，没有参数化模式的方法。文档要么有效，要么无效。他们今天不能有效，明天无效。所以没有办法做你想要做的事。
您可以使用断言：<xs:assert test="$value le current-date()"/>在XSD1.1中完成这一任务。
