从 SQL 数据源呈现 HTML 中的换行符

Question

我将一列的多行作为一行和一列返回：

SELECT STUFF((
                SELECT '<br/>' + Notes 
                FROM DailyTaskHours
                WHERE Notes IS NOT NULL
                    AND Notes <> ''
                    AND NonScrumStoryId = DTH.NonScrumStoryId
                FOR XML PATH('')
                ), 1, 1, '')
                )

我想在 ASP.NET 中连接的每一行之间插入换行符，但我的方法不起作用：

如您所见，
正在被数据库引擎替换为 <br /> 如何获取数据库中的换行符，以便在网页上间隔呈现？

这是我正在处理的整个控件以供参考：

Answer 1

您的数据库引擎没有这样做，ASP.NET 正在这样做。这是一项有助于防止 XSS 的安全功能。

您可以在绑定字段上设置 HtmlEncode 属性，如MSDN 链接中的示例：

<asp:boundfield datafield="City"
            htmlencode="false"
            headertext="City"/>

Answer 2

在您的应用程序中，您可能希望对字符串执行HttpUtility.HtmlDecode。

来自 MSDN：

将已为 HTTP 传输进行 HTML 编码的字符串转换为已解码的字符串。

http://msdn.microsoft.com/en-us/library/system.web.httputility.htmldecode(v=vs.110).aspx

事实上，最好将<br /> 附加在应用程序本身中，而不是在查询中。在查询本身以这种方式处理数据并不典型。通常，为您的应用程序获取的数据不应附加任何表示层或视图类型的东西，除非这正是它在数据库中的存在方式。为您的应用程序保存该工作。例如，如果这是一个 MVC 应用程序，您可以考虑在控制器中进行此类工作。

现在我从您刚刚发布的代码中看到了您问题的完整上下文，我将在下面为任何未来的读者添加我在此答案中所做的相同评论。自从我进入 ASP.NET WebForms 领域以来已经有一段时间了，所以我可能有点生疏了！我的评论...

有更好的方法来处理这个问题，但我担心它可能超出了这个问题的范围，因为它还涉及您如何创建数据源。如果您有兴趣，可以快速搜索 in this example 中的 Repeater，在 GridView 和具有两个相关数据表的数据源中。这是一个旧示例 (.NET 2.0)，但它可能仍然有效，或者至少可以帮助您找到更好的示例。

现在需要一个替代答案吗？ ...

我可以想到针对您的问题的另一种选择。在查询中，您可以附加一个简单的新行（\n 或 SQL 中的 char(10)），而不是附加 <br />。然后，不要在GridView 中为该字段使用asp:BoundColumn，而是使用asp:TemplateField 并在模板内部，将\n 替换为<br />。就像我之前说的，我已经有一段时间没有做 WebForms 了，但我相信它看起来像：

<%#Eval("Task").Replace("\n", "<br />")%>

我想您可以使用HtmlDecode 进行类似操作，但我不喜欢在这些查询结果中看到 HTML 标记。

Answer 3

SELECT REPLACE((SELECT '<br/>' + Notes 
               FROM DailyTaskHours
               WHERE Notes IS NOT NULL
                 AND Notes <> ''
                 AND NonScrumStoryId = DTH.NonScrumStoryId
            FOR XML PATH('')) ,'&lt;br/&gt;','<br/>')

Answer 4

亲爱的使用以下

SELECT STUFF((
            SELECT '<br/>' + Notes 
            FROM DailyTaskHours
            WHERE Notes IS NOT NULL
                AND Notes <> ''
                AND NonScrumStoryId = DTH.NonScrumStoryId
            FOR XML PATH(''),TYPE).value('.','NVARCHAR(MAX)')
            ), 1, 1, '')
            )

或

  SELECT STUFF((
            SELECT '<br/>' + Notes 
            FROM DailyTaskHours
            WHERE Notes IS NOT NULL
                AND Notes <> ''
                AND NonScrumStoryId = DTH.NonScrumStoryId
            FOR XML PATH(''),TYPE).value('(./text())[1]','NVARCHAR(MAX)')
            ), 1, 1, '')
            )

Answer 5

测试数据

DECLARE @DailyTaskHours TABLE (NonScrumStoryId INT, Notes NVARCHAR(100))
INSERT INTO @DailyTaskHours VALUES
(1, 'Note one for value one'),(1, 'Note two for value one'),(1, 'Note three for value one'),
(2, 'Note one for value Two'),(2, 'Note Two for value Two'),(2, 'Note Three for value two')

查询

SELECT STUFF((SELECT '<br/>' + Notes 
                FROM @DailyTaskHours
                WHERE Notes IS NOT NULL
                AND Notes <> ''
                AND NonScrumStoryId = DTH.NonScrumStoryId
                FOR XML PATH(''), TYPE)
               .value('.','NVARCHAR(MAX)'), 1, 5, '') AS NotesList
FROM @DailyTaskHours DTH
GROUP BY NonScrumStoryId

结果集

╔════════════════════════════════════════════════════════════════════════════════╗
║                                   NotesList                                    ║
╠════════════════════════════════════════════════════════════════════════════════╣

║ Note one for value Two<br/>Note Two for value Two<br/>Note Three for value two ║
╚════════════════════════════════════════════════════════════════════════════════╝

使用交叉应用

SELECT DISTINCT STUFF(REPLACE(C.NotesList,'Break_Tag', '<br/>') , 1, 5, '') AS NotesList
FROM @DailyTaskHours DTH CROSS APPLY 
                         (SELECT 'Break_Tag' + Notes  [text()]
                          FROM @DailyTaskHours
                          WHERE Notes IS NOT NULL
                          AND Notes <> ''
                          AND NonScrumStoryId = DTH.NonScrumStoryId
                          FOR XML PATH('')
                          )C(NotesList)
