这个xpath选择器：

/Matrix/Rows/Row[descendant::Visible='1']/Columns/Column[descendant::ID='1']/Value/text()

我如何以及以下条件：从选择中排除具有Column / ID ='24'的Row节点以及它的Column / Value / text（）=''

尝试过这样的事情（没有用）：

/Matrix/Rows/Row[descendant::Visible='1' and (descendant::ID='24' and descendant::Value!='')]/Columns/Column[descendant::ID='1']/Value/text()

Answer 1

您应该使用not()并指定您要为此过滤器寻找的节点：

/Matrix/Rows/Row[descendant::Visible='1' and not(./Columns/Column[ID='24' and Value=''])]/Columns/Column[descendant::ID='1']/Value/text()

Xpath添加条件以排除具有特定后代元素而没有值的元素
