    </LowestOfferListing>
</LowestOfferListings>

我试图计算LowestOfferListing所有ShipsDomestically='False'元素的数量，同时忽略任何命名空间约束。

这将让我了解所有列表：

count(//*[local-name()='LowestOfferListing'])

如何使用子元素过滤掉那些？

我尝试了这些，但它们不起作用：

count(//*[local-name()='LowestOfferListing']/descendant::*[not(ShipsDomestically='False')])
count(//*[local-name()='LowestOfferListing'][not(ShipsDomestically='False')])
count(//*[local-name()='LowestOfferListing'][not(local-name()='ShipsDomestically'='False')])

Answer 1

这应该有效

count(//*[local-name()='LowestOfferListing' and descendant::ShipsDomestically = 'False'])

排除具有特定值的子项的xpath元素
