XmlDocument.CreateProcessingInstruction 方法
创建一个具有指定名称和数据的 XmlProcessingInstruction。
**命名空间:**System.Xml
**程序集:**System.Xml（在 system.xml.dll 中）
语法
声明
Public Overridable Function CreateProcessingInstruction ( _
target As String, _
data As String _
) As XmlProcessingInstruction
用法
Dim instance As XmlDocument
Dim target As String
Dim data As String
Dim returnValue As XmlProcessingInstruction
returnValue = instance.CreateProcessingInstruction(target, data)
public virtual XmlProcessingInstruction CreateProcessingInstruction (
string target,
string data
)
public:
virtual XmlProcessingInstruction^ CreateProcessingInstruction (
String^ target,
String^ data
)
public XmlProcessingInstruction CreateProcessingInstruction (
String target,
String data
)
public function CreateProcessingInstruction (
target : String,
data : String
) : XmlProcessingInstruction
参数
- target
处理指令的名称。
- data
处理指令的数据。
返回值
新的 XmlProcessingInstruction。
备注
尽管此方法在文档的上下文中创建新对象，但它并不自动将新对象添加到文档树。若要添加新对象，必须显式调用节点插入方法之一。
根据 W3C 可扩展标记语言 (XML) 1.0 建议 (www.w3.org/TR/1998/REC-xml-19980210)，ProcessingInstruction 节点可包含在 Document 节点和 Element 节点中，并且当 EntityReference 节点不是 Attribute 节点的子级时，ProcessingInstruction 节点还可包含在 EntityReference 节点中。
示例
下面的示例创建一个 ProcessingInstruction 节点并将其添加到文档中。
Imports System
Imports System.IO
Imports System.Xml
public class Sample
public shared sub Main()
Dim doc as XmlDocument = new XmlDocument()
' Create a procesing instruction.
Dim newPI as XmlProcessingInstruction
Dim PItext as String = "type='text/xsl' href='book.xsl'"
newPI = doc.CreateProcessingInstruction("xml-stylesheet", PItext)
' Display the target and data information.
Console.WriteLine("<?{0} {1}?>", newPI.Target, newPI.Data)
' Add the processing instruction node to the document.
doc.AppendChild(newPI)
end sub
