XmlReader.ReadAttributeValue Method

When overridden in a derived class, parses the attribute value into one or more Text, EntityReference, or EndEntity nodes.

[Visual Basic]
Public MustOverride Function ReadAttributeValue() As Boolean
public abstract bool ReadAttributeValue();
public: virtual bool ReadAttributeValue() = 0;
public abstract function ReadAttributeValue() : Boolean;

Return Value

true if there are nodes to return.

false if the reader is not positioned on an attribute node when the initial call is made or if all the attribute values have been read.

An empty attribute, such as, misc="", returns true with a single node with a value of String.Empty.


Use this method after calling MoveToAttribute to read through the text or entity reference nodes that make up the attribute value. The Depth of the attribute value nodes is one plus the depth of the attribute node; it increments and decrements by one when you step into and out of general entity references.

Implementations of XmlReader that cannot expand general entities return the general entities as a single empty(Value is String.Empty) EntityReference node.


See ReadAttributeValue (in the XmlTextReader class) for an example using this method.
