在文檔中的任意位置選擇包含xml節點的行

我想返回在sql中具有特定屬性的xml。在文檔中的任意位置選擇包含xml節點的行

的XML看起來是這樣的：

<Settings> 
    <Item Name="ColorScheme" Type="XDocument"> 
    <ColorScheme> 
    <ItemStyle Name="element-song" Title="Song" ForeColor="#0538ac" BackColor="#e8f1fa" Media="1" /> 
    <ItemStyle Name="element-song-print" Title="Song (print)" ForeColor="#0538ac" BackColor="" Media="2" /> 
    <ItemStyle Name="element-spot" Title="Spot" ForeColor="#048b27" BackColor="#e9ffee" Media="1" /> 
    <ItemStyle Name="element-spot-print" Title="Spot (print)" ForeColor="#048b27" BackColor="" Media="2" /> 
    <ItemStyle Name="element-programming" Title="Programming" ForeColor="#0538ac" BackColor="#e8f1fa" Media="1" /> 
    <ItemStyle Name="element-programming-print" Title="Programming (print)" ForeColor="#0538ac" BackColor="" Media="2" /> 
    <ItemStyle Name="element-continued-programming" Title="Continued programming" ForeColor="#0538ac" BackColor="#e8f1fa" Media="1" /> 
    <ItemStyle Name="element-continued-programming-print" Title="Continued programming (print)" ForeColor="#0538ac" BackColor="" Media="2" /> 
    </ColorScheme> 
    </Item> 
    <Item Name="SendWeeklyNewAccountEmail" Type="Boolean">False</Item> 
    <Item Name="UseEstimatedDurationsForAnalysis" Type="Boolean">True</Item> 
    <Item Name="CalendarStyle" Type="Int32">1</Item> 
    <Item Name="IncludeAdExForAnalysis" Type="Boolean">True</Item> 
</Settings>

我用它來選擇包含的色彩方案屬性這些字段的查詢是：

SELECT * FROM CustomSettings WITH (NOLOCK)WHERE settings_xml.value('(/Settings/Item/@Name)[1]', 'varchar(25)') = 'ColorScheme' order by 1 desc

我遇到的問題是，它只是選擇具有ColorScheme作爲第一個字段的xml。如果它位於xml中（這是一種可能性），它不會被選中。我明白這是由於我在查詢中有[1]，但如果我刪除了這部分，查詢就不會被糾正。那麼我該如何放置它來使其不具體位置？

SELECT * 
FROM @x x1 
WHERE x1.x.exist('(/Settings/Item[@Name="ColorScheme"])') = 1
