'Declaration
Public Sub WriteAttributeString ( _
	localName As String, _
	value As String _
)

Parameters

localName

The local name of the attribute.
value
Type: System.String
The value of the attribute.

ExceptionCondition
InvalidOperationException

The state of writer is not WriteState.Element or writer is closed.

ArgumentException

The xml:space or xml:lang attribute value is invalid.

WriteAttributeString does the following:

  • If the attribute value includes double or single quotes, they are replaced with " and ' respectively.

  • If writing an xml:space attribute, the writer verifies the attribute value is valid. (Valid values are preserve or default.)

  • If writing an xml:lang attribute, the writer does not verify that the attribute value is valid according to the W3C XML 1.0 recommendation.


Dim output As New StringBuilder()

Dim settings As New XmlWriterSettings()
settings.Indent = True
Using writer As XmlWriter = XmlWriter.Create(output, settings)

    ' Write the root element.
    writer.WriteStartElement("order")

    ' Write an element with attributes.
    writer.WriteStartElement("item")
    writer.WriteAttributeString("date", "2/19/01")
    writer.WriteAttributeString("orderID", "136A5")

    ' Write a full end element. Because this element has no
    ' content, calling WriteEndElement would have written a
    ' short end tag '/>'.
    writer.WriteFullEndElement()

    writer.WriteEndElement()

    ' Write the XML to file and close the writer
End Using
OutputTextBlock.Text = output.ToString()
