存储过程代码：

SELECT  
    t.v.value('.','nvarchar(max)') as a,
    t.v.value('@href','nvarchar(max)') as b
FROM    
    @html.nodes('table[1]/tr/td/a') as t(v)

Answer 1

您可以在节点方法的XQuery表达式中指定它。

SELECT  
    t.v.value('.','nvarchar(max)') as a,
    t.v.value('@href','nvarchar(max)') as b
FROM    
    @html.nodes('table[1]/tr[not(@align="center")]/td/a') as t(v)
