簡介Introduction

XmlDataSource控制項是一種資料來源控制項,可將 XML 資料提供給資料繫結控制項。The XmlDataSource control is a data source control that presents XML data to data-bound controls. XmlDataSource資料繫結控制項可以使用此控制項來顯示階層式和表格式資料。The XmlDataSource control can be used by data-bound controls to display both hierarchical and tabular data. XmlDataSource控制項通常用來顯示唯讀案例中的階層式 XML 資料。The XmlDataSource control is typically used to display hierarchical XML data in read-only scenarios. 因為此 XmlDataSource 控制項會擴充 HierarchicalDataSourceControl 類別,所以它會使用階層式資料。Because the XmlDataSource control extends the HierarchicalDataSourceControl class, it works with hierarchical data. XmlDataSource 控制項也會執行 IDataSource 介面,並可搭配表格式或清單樣式的資料使用。The XmlDataSource control also implements the IDataSource interface and works with tabular, or list-style, data.

注意

基於安全性考慮,任何 XmlDataSource 控制項屬性都不會儲存在 view 狀態中。For security purposes, none of the XmlDataSource control properties are stored in view state. 因為技術上可能會將用戶端上的 view 狀態內容解碼,所以儲存資料結構或其內容的機密資訊可能會讓您暴露在資訊洩漏威脅中。Since it is technically possible to decode the contents of view state on the client, storing sensitive information about the data structure or its contents could expose you to an information disclosure threat. 請注意,如果您需要將屬性(例如 XPath 屬性)儲存在「視圖」狀態中,您可以在指示詞上設定,以啟用加密來保護內容 ViewStateEncryptionMode @ PageNote that if you need to store information such as XPath property in view state, you can enable encryption to protect the contents by setting ViewStateEncryptionMode on the @ Page directive.

頁面開發人員使用 XmlDataSource 控制項來顯示使用資料繫結控制項的 XML 資料。Page developers use the XmlDataSource control to display XML data using data-bound controls.

XML 資料的來源Sources of XML Data

XmlDataSource通常會從屬性所指定的 xml 檔案載入 xml 資料 DataFileThe XmlDataSource typically loads XML data from an XML file, which is specified by the DataFile property. 資料來源控制項也可以使用屬性,以字串形式直接儲存 XML 資料 DataXML data can also be stored directly by the data source control in string form using the Data property. 如果您想要在資料繫結控制項顯示 XML 資料之前進行轉換,您可以為轉換提供可擴充的樣式表單語言 (XSL) 樣式表單。If you want to transform the XML data before it is displayed by a data-bound control, you can provide an Extensible Stylesheet Language (XSL) style sheet for the transformation. 如同 XML 資料,您通常會從檔案載入樣式表單(由屬性工作表示), TransformFile 但您也可以使用屬性直接將其儲存為字串格式 TransformAs with the XML data, you typically load the style sheet from a file, indicated by the TransformFile property, but you can also store it in string form directly using the Transform property.

更新 XML 資料Updating XML Data

XmlDataSource控制項通常用於資料繫結控制項顯示 XML 資料的唯讀資料案例中。The XmlDataSource control is commonly used in read-only data scenarios where a data-bound control displays XML data. 不過,您也可以使用 XmlDataSource 控制項來編輯 XML 資料。However, you can also use the XmlDataSource control to edit XML data. 若要編輯 XML 資料,請呼叫 GetXmlDocument 方法來取出 XmlDataDocument 物件,該物件為 XML 資料的記憶體中表示。To edit the XML data, call the GetXmlDocument method to retrieve an XmlDataDocument object that is an in-memory representation of the XML data. 您可以使用它所包含的和物件所公開的物件模型 XmlDataDocumentXmlNode 或使用 XPath 篩選運算式來操作檔中的資料。You can use the object model exposed by the XmlDataDocument and XmlNode objects it contains or use an XPath filtering expression to manipulate data in the document. 當您對 XML 資料的記憶體中標記法進行變更時,您可以藉由呼叫方法將其儲存至磁片 SaveWhen you have made changes to the in-memory representation of the XML data, you can save it to disk by calling the Save method.

控制項的編輯功能有一些限制 XmlDataSourceThere are some restrictions to the editing capabilities of the XmlDataSource control:

  • XML 資料必須從屬性所指定的 XML 檔案載入 DataFile ,而不是從屬性中指定的內嵌 xml 載入 DataThe XML data must be loaded from an XML file that is indicated by the DataFile property, not from inline XML specified in the Data property.

  • 或屬性中不能指定任何 XSLT Transform 轉換 TransformFileNo XSLT transformation can be specified in the Transform or TransformFile properties.

  • Save方法不會依不同的要求處理並行儲存作業。The Save method does not handle concurrent save operations by different requests. 如果有一位以上的使用者透過來編輯 XML 檔案 XmlDataSource ,就不保證所有使用者都是使用相同的資料來運作。If more than one user is editing an XML file through the XmlDataSource, there is no guarantee that all users are operating with the same data. 作業也可能 Save 因為這些相同的並行問題而失敗。It is also possible for a Save operation to fail due to these same concurrency issues.

指定 XSL 轉換Specifying an XSL Transformation

使用 XML 資料執行的一般作業,會將它從一個 XML 資料集轉換成另一個資料集。A common operation performed with XML data is transforming it from one XML data set into another. XmlDataSource控制項支援 xml 轉換與 TransformTransformFile 屬性,這些屬性會指定 xsl 樣式表單先套用至 XML 資料,然後再傳遞至資料繫結控制項,以及 TransformArgumentList 屬性(property),這個屬性可讓您提供在轉換期間 xsl 樣式表單使用的動態 XSLT 樣式表單引數。The XmlDataSource control supports XML transformations with the Transform and TransformFile properties, which specify an XSL style sheet to apply to XML data before it is passed to a data-bound control, and the TransformArgumentList property, which enables you to supply dynamic XSLT style sheet arguments to be used by an XSL style sheet during the transformation. 如果您使用屬性指定 XPath 篩選運算式,則會在 XPath 轉換進行之後套用。If you specify an XPath filtering expression using the XPath property, it is applied after the transformation takes place.

注意

類別會使用已被 XmlDataSource 取代的 XslTransform 類別來執行 XSL 轉換。The XmlDataSource class uses the deprecated XslTransform class to perform XSL transformations. 如果您想要使用在類別淘汰之後引進的樣式表單功能 XslTransform ,請使用類別手動套用轉換 XslCompiledTransformIf you want to use style sheet features that were introduced after the XslTransform class was deprecated, apply the transforms manually by using the XslCompiledTransform class.

使用 XPath 運算式進行篩選Filtering using an XPath Expression

根據預設, XmlDataSource 控制項會載入屬性所識別之 xml 檔案中的所有 xml 資料 DataFile ,或在屬性中找到內嵌 Data ,但您可以使用 XPath 運算式來篩選資料。By default, the XmlDataSource control loads all the XML data in the XML file identified by the DataFile property or found inline in the Data property, but you can filter the data using an XPath expression. XPath屬性支援在載入和轉換 XML 資料之後套用的 XPath 語法篩選。The XPath property supports an XPath-syntax filter that is applied after XML data is loaded and transformed.

CachingCaching

基於效能考慮,預設會啟用控制項的快取 XmlDataSourceFor performance purposes, caching is enabled for the XmlDataSource control by default. 每次要求頁面時,在伺服器上開啟和讀取 XML 檔案可以降低應用程式的效能。Opening and reading an XML file on the server every time a page requested can reduce the performance of your application. 快取可讓您減少伺服器上的處理負載,代價是 Web 服務器上的記憶體。在大部分情況下,這是很好的取捨。Caching lets you reduce the processing load on your server at the expense of memory on the Web server; in most cases this is a good trade-off. XmlDataSourceEnableCaching 屬性設定為 true ,且屬性設定為快取在快取 CacheDuration 失效之前儲存資料的秒數時,會自動快取資料。The XmlDataSource automatically caches data when the EnableCaching property is set to true, and the CacheDuration property is set to the number of seconds that the cache stores data before the cache is invalidated. 您可以使用 CacheExpirationPolicy 來進一步微調資料來源控制項的快取行為。You can use the CacheExpirationPolicy to further fine-tune the caching behavior of the data source control.

Data View 物件Data View Object

由於 XmlDataSource 控制項支援顯示階層式資料的資料繫結控制項,以及顯示表格式資料的控制項,因此資料來源控制項支援其基礎 XML 資料上的多個資料來源 view 物件類型。Because the XmlDataSource control supports data-bound controls that display hierarchical data as well as controls that display tabular data, the data source control supports multiple types of data source view objects on its underlying XML data. XmlDataSource XmlDataSourceView 當控制項與顯示表格式資料的資料繫結控制項搭配使用時,控制項會抓取單一命名物件。The XmlDataSource control retrieves a single named XmlDataSourceView object when used with a data-bound control that displays tabular data. GetViewNames方法會識別這個單一命名視圖。The GetViewNames method identifies this single named view. 當搭配顯示階層式資料的資料繫結控制項使用時, XmlDataSource 控制項會 XmlHierarchicalDataSourceView 針對任何傳遞至方法的唯一階層式路徑,取得 GetHierarchicalViewWhen used with a data-bound control that displays hierarchical data, the XmlDataSource control retrieves an XmlHierarchicalDataSourceView for any unique hierarchical path passed to the GetHierarchicalView method.
