XmlReader.MoveToElement Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

When overridden in a derived class, moves to the element that contains the current attribute node.

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

Syntax

'Declaration
Public MustOverride Function MoveToElement As Boolean

public abstract bool MoveToElement()

Return Value

Type: System.Boolean
true if the reader is positioned on an attribute (the reader moves to the element that owns the attribute); false if the reader is not positioned on an attribute (the position of the reader does not change).

Remarks

Use this method to return to an element after navigating through its attributes. This method moves the reader to one of the following node types: Element, DocumentType, or XmlDeclaration.

Examples

Dim output As 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>"

        Next i
        reader.MoveToElement() ' Moves the reader back to the element node.
    End If
