Note

This method is not called for entity references appearing as part of attribute values.

Parameters
name:String

The name of the entity.

augs:Augmentations

Additional information that may include infoset augmentations

Exceptions
XNIException:
Thrown by handler to signal an error.

public XMLDocumentSource getDocumentSource()

Returns the document source.

ignorableWhitespaceback to summary
public void ignorableWhitespace(XMLString text, Augmentations augs) throws XNIException

Ignorable whitespace. For this method to be called, the document source must have some way of determining that the text containing only whitespace characters should be considered ignorable.

Typically, a processing instruction's data will contain a series of pseudo-attributes. These pseudo-attributes follow the form of element attributes but are not parsed or presented to the application as anything other than text. The application is responsible for parsing the data.

Parameters
target:String

The target.

The data or null if none specified.
