//i want to get all the href inside a tag in li which is in ol inside a class named "odd" i have tried everything by combing them into 1 div as well,

var getcatgory = htmlDoc.DocumentNode.SelectNodes(
    @"//d1[@id='narrow-by-list']/div[@class='odd']/ol/li")

i have checked NodeCollection as well,but that is returning null

Answer 1

应为//dl（字母l），而不是//d1（数字1）。

Answer 2

根据您的示例HTML，dl没有子元素div[@class='odd']，而应该是dd[@class='odd']。所以这是一个可能返回目标<a>元素的XPath：

//dl[@id='narrow-by-list']/dd[@class='odd']/ol/li/a
