Question

我有以下XPATH似乎是为该类别选择了正确的产品，但是当我的XPath中的qtyInStock值为0时，错误地选择了产品qtyInStock＆gt; 0.任何人都可以看到这有什么问题，我认为我的语法不正确。

/ products / product [category = 1234或additionalCategories / catID = 1234 和qtyInStock＆gt; 0]

请尝试以下（注意括号分组）

/products/product[(category = 1234 or additionalCategories/catID =1234) and qtyInStock > 0]

XPATH语法从XML中选择产品
