XPATH語法從XML中選擇產品

我有以下XPATH，它似乎是爲類別選擇正確的產品，但是當我的XPath中的qtyInStock值爲0時，我錯誤地選擇了產品我的狀態qtyInStock> 0。任何人都可以看到這個錯誤，我認爲我的語法不正確。XPATH語法從XML中選擇產品

/產品/產品[類別= 1234或additionalCategories/CATID = 1234 和qtyInStock> 0]

你試過：'/產品/產品[（類別= 1234或additionalCategories/CATID = 1234）和qtyInStock> 0]' – Pawel

的and操作符比or操作者更高的優先級。詳情請參閱here。

而是嘗試下面的（注意用括號分組）

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