Public Sub New (xmlFragment As String, fragType As XmlNodeType, context As XmlParserContext)

Parameters

xmlFragment
String

The string containing the XML fragment to parse.

fragType
XmlNodeType

The XmlNodeType of the XML fragment. This also determines what the fragment string can contain. (See table below.)

Exceptions

fragType is not an Element, Attribute, or DocumentXmlNodeType.

xmlFragment is null.

Examples

The following example parses an XML fragment. It uses the XmlParserContext and its XmlNamespaceManager to handle namespace resolution.

   // Create the reader. 
   XmlTextReader^ reader = gcnew XmlTextReader( xmlFrag,XmlNodeType::Element,context );
   
   // Parse the XML.  If they exist, display the prefix and  
   // namespace URI of each element.
   while ( reader->Read() )

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

This constructor parses the given string as a fragment of XML. If the XML fragment is an element or attribute, you can bypass the root level rules for well-formed XML documents. This constructor can handle strings returned from ReadInnerXml.

The following table lists valid values for fragType and how the reader parses each of the different node types.

XmlNodeType Fragment May Contain
Element Any valid element content (for example, any combination of elements, comments, processing instructions, CDATA sections, text, and entity references).

An XML declaration can also be supplied. This allows you to specify the encoding for the XML fragment, rather than having to set it on the XmlParserContext object.
Attribute The value of an attribute (the part inside the quotes).
Document The contents of an entire XML document. This enforces document level rules.

XmlTextReader(String, TextReader, XmlNameTable)

Source:
XmlTextReader.cs
Source:
XmlTextReader.cs
Source:
XmlTextReader.cs

Initializes a new instance of the XmlTextReader class with the specified URL, TextReader and XmlNameTable.

public:
 XmlTextReader(System::String ^ url, System::IO::TextReader ^ input, System::Xml::XmlNameTable ^ nt);
public XmlTextReader (string url, System.IO.TextReader input, System.Xml.XmlNameTable nt);
new System.Xml.XmlTextReader : string * System.IO.TextReader * System.Xml.XmlNameTable -> System.Xml.XmlTextReader
Public Sub New (url As String, input As TextReader, nt As XmlNameTable)

Parameters

url
String

The URL to use for resolving external resources. The BaseURI is set to this value. If url is null, BaseURI is set to String.Empty.

input
TextReader

The TextReader containing the XML data to read.

nt
XmlNameTable

The XmlNameTable to use.

Exceptions

The nt value is null.

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

It is assumed that the TextReader is already set to the correct encoding. This is used by clients that have already read some things from the stream in a multi-part MIME scenario.

public:
 XmlTextReader(System::IO::Stream ^ xmlFragment, System::Xml::XmlNodeType fragType, System::Xml::XmlParserContext ^ context);

new System.Xml.XmlTextReader : System.IO.Stream * System.Xml.XmlNodeType * System.Xml.XmlParserContext -> System.Xml.XmlTextReader
Public Sub New (xmlFragment As Stream, fragType As XmlNodeType, context As XmlParserContext)

Parameters

xmlFragment
Stream

The stream containing the XML fragment to parse.

fragType
XmlNodeType

The XmlNodeType of the XML fragment. This also determines what the fragment can contain. (See table below.)

context
XmlParserContext

The XmlParserContext in which the xmlFragment is to be parsed. This includes the XmlNameTable to use, encoding, namespace scope, the current xml:lang, and the xml:space scope.

Exceptions

fragType is not an Element, Attribute, or Document XmlNodeType.

xmlFragment is null.

Attribute The value of an attribute (the part inside the quotes).
Document The contents of an entire XML document. This enforces document level rules.

The reader uses the following to determine the encoding of the stream.

  1. Checks the XmlParserContext.Encoding property to determine the encoding.

  2. If the Encoding property is null, the reader checks for a byte-order mark at the beginning of the stream.

  3. If the Encoding property is null, and no byte-order mark is found, the reader assumes the stream is encoded in UTF-8.

                        Console.Write(reader.Name)
                    Case XmlNodeType.EndElement
                        Console.Write("</{0}>", reader.Name)
                End Select
            End While
        
        Finally
            If Not (reader Is Nothing) Then
                reader.Close()
            End If
        End Try
    End Sub
End Class

The example uses the file, items.xml, as input.


<?xml version="1.0"?>
<!-- This is a sample XML document -->
<!DOCTYPE Items [<!ENTITY number "123">]>
<Items>
  <Item>Test with an entity: &number;</Item>
  <Item>test with a child element <more/> stuff</Item>
  <Item>test with a CDATA section <![CDATA[<456>]]> def</Item>
  <Item>Test with an char entity: A</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>
</Items>

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

If the file is located on a resource that requires access credentials, use the XmlResolver property to specify the necessary credentials.

Note

In version 1.1 of the .NET Framework, partially trusted code cannot set the XmlResolver property. The workaround is to create an XmlUrlResolver with the necessary credentials, pass the URI to the XmlUrlResolver.GetEntity method, and then construct the XmlTextReader using the resulting Stream object. The workaround is described in the following C# code.

// Create a resolver with the necessary credentials.
XmlUrlResolver resolver = new XmlUrlResolver();
NetworkCredential nc = new NetworkCredential(SecurelyStoredUserName, SecurelyStoredPassword, SecurelyStoredDomain);
resolver.Credentials = nc;
// Get a Stream object containing the XML file.
Uri myUri = new Uri ("http://myServer/data/books.xml");
Stream s=(Stream)resolver.GetEntity(myUri, null, typeof(Stream));
// Construct a reader using the Stream object.
XmlTextReader reader = new XmlTextReader(s);

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

It is assumed that the TextReader is already set to the correct encoding. This is used by clients that have already read some things from the stream in a multi-part MIME scenario.
