XmlReader.ReadElementContentAsString Method

Reads the current element and returns the contents as a String object.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

'Declaration
Public Overridable Function ReadElementContentAsString As String

Return Value

Type: System.String
The element content as a String object.

ExceptionCondition
InvalidOperationException

The XmlReader is not positioned on an element.

XmlException

The current element contains child elements.

-or-

The element content cannot be converted to a String object.

ArgumentNullException

The method is called with Nothing arguments.

This method reads the start tag, the contents of the element, and moves the reader past the end element tag. It expands entities and ignores processing instructions and comments. The element can only contain simple content. That is, it cannot have child elements.

The following example uses the XmlReader methods to read the content of elements and attributes.


Dim output As StringBuilder = New StringBuilder()

Dim xmlString As String = _
    "<bookstore>" & _
            "<book genre='autobiography' publicationdate='1981-03-22' ISBN='1-861003-11-0'>" & _
                "<title>The Autobiography of Benjamin Franklin</title>" & _
                "<author>" & _
                    "<first-name>Benjamin</first-name>" & _
                    "<last-name>Franklin</last-name>" & _
                "</author> " & _
                "<price>8.99</price>" & _
            "</book>" & _
        "</bookstore>"

' Create an XmlReader
Using reader As XmlReader = XmlReader.Create(New StringReader(xmlString))

    reader.ReadToFollowing("book")
    reader.MoveToFirstAttribute()
    Dim genre As String = reader.Value
    output.AppendLine("The genre value: " + genre)

    reader.ReadToFollowing("title")
    output.AppendLine("Content of the title element: " + reader.ReadElementContentAsString())
End Using

OutputTextBlock.Text = output.ToString()
