我试图找到一种方法来判断日期是否在日期之外。可以有任意数量的元素和元素。上述情况在所有情况下都应失败。下面是我试过的。然而，我觉得它的出路，因为它只找到了第一个。任何帮助都是非常感谢的！

   <sch:pattern name="Testing Start and End dates">
                                                                                <sch:rule context="blk:InvBlock">
                                                                                    <sch:report test="translate(blk:InvBlockDates/@Start, '-', '') &lt;= translate(blk:RoomTypes/blk:RoomType/blk:RoomTypeAllocations/blk:RoomTypeAllocation/@Start, '-', '') or translate(blk:InvBlockDates/@End, '-', '') &lt;= translate(blk:RoomTypes/blk:RoomType/blk:RoomTypeAllocations/blk:RoomTypeAllocation/@End, '-', '')"> Allocation @Start and @End dates can not be outside the Block @Start and @End dates. </sch:report>
                                                                                </sch:rule>
                                                                            </sch:pattern> 

Answer 1

我不确定您是否想报告验证错误，如果至少有一个TypeAllocation与错误的Start或End，或者您想要检查所有这些。如果您只想检查其中至少一个错误，则可以使用

<sch:pattern>
    <sch:rule context="Block">
        <sch:report test="Types/Type/TypeAllocations/TypeAllocation[
                            translate(@Start, '-', '') > translate(current()/BlockDates/@Start, '-', '')
                            or
                            translate(@End, '-', '') > translate(current()/BlockDates/@End, '-', '')]"> Allocation @Start and @End dates can not be outside the Block @Start and @End dates. </sch:report>
    </sch:rule>
</sch:pattern> 

我认为。如果Schematron的版本不支持使用current()函数，那么在示例的上下文中，我建议您可以使用ancestor::Block而不是current()：

<sch:pattern>
    <sch:rule context="Block">
        <sch:report test="Types/Type/TypeAllocations/TypeAllocation[
                            translate(@Start, '-', '') > translate(ancestor::Block/BlockDates/@Start, '-', '')
                            or
                            translate(@End, '-', '') > translate(ancestor::Block/BlockDates/@End, '-', '')]"> Allocation @Start and @End dates can not be outside the Block @Start and @End dates. </sch:report>
    </sch:rule>
</sch:pattern> 

Answer 2

我能够使用以下方法完成这项工作。非常感谢你的帮助马丁！

<sch:rule context="Block">
    <sch:report test="Types/Type/TypeAllocations/TypeAllocation[
    translate(@Start, '-', '') &lt; translate(ancestor::Block/BlockDates/@Start, '-', '') ]
    or
    Types/Type/TypeAllocations/TypeAllocation[translate(@End, '-', '') &gt; translate(ancestor::Block/BlockDates/@End, '-', '')] ">
    Allocation @Start and @End dates can not be outside the Block @Start and @End dates.
    </sch:report>
</sch:rule>
