如何从XMLData字段中的多个节点获取多行？

       <description>&lt;p&gt;Dit is een faketekst. Alles wat hier staat is slechts om een indruk te geven van het grafische effect van tekst op deze plek. Wat u hier leest is een voorbeeldtekst. Deze wordt later vervangen door de uiteindelijke tekst, die nu nog niet bekend is. De faketekst is dus een tekst die eigenlijk nergens over gaat. Het grappige is, dat mensen deze toch vaak lezen. Zelfs als men weet dat het om een faketekst gaat, lezen ze toch door.&lt;/p&gt;

SELECT T.C.value('.', 'varchar(100)') as productid 
 
FROM @myOrder.nodes('(/genxml/items/genxml/productid)') as T(C)

其中给出一个漂亮的两排，这两种产品的顺序。 但我怎么能得到一些额外的列，与f.i.节点/ genxml/items/genxml/productname中的产品名称

一种选择是在genxml处停止，而不是将更多级别导航到产品，然后选择您的详细信息。

更新：增加了一个更多级别的导航。你可以继续扩展这个每个级别，取决于你开始的地方。由于我们在T（C）中下降到/ genxml/items/genxml /，我们然后使用这个级别并在T1（C2）中再次下降。我去了这个范围（样本），以保持我的select部分小/可读。

SELECT 
    T.C.query('productid').value('.', 'varchar(100)') AS productid 
    ,T.C.query('productname').value('.', 'varchar(100)') productname 
    ,T.C.query('totalweight').value('.', 'float') totalweight 
    ,T1.C2.query('txtbarcode').value('.', 'varchar(100)') txtbarcode 
    FROM @myOrder.nodes('(/genxml/items/genxml/.)') as T(C)  
    CROSS APPLY T.c.nodes('(productxml/genxml/models/genxml/textbox/.)') as T1(C2) 
    --few levels down navigatig all the way to textbox  

该查询仅用于导航产品详细信息与给定的示例。希望能帮助到你。
