Interface XMLAttributes

public interface XMLAttributes

The XMLAttributes interface defines a collection of attributes for an element. In the parser, the document source would scan the entire start element and collect the attributes. The attributes are communicated to the document handler in the startElement method.

The attributes are read-write so that subsequent stages in the document pipeline can modify the values or change the attributes that are propagated to the next stage.

Method Detail

### addAttribute

    public int addAttribute(QName attrName,
                            java.lang.String attrType,
                            java.lang.String attrValue)

  Adds an attribute. The attribute's non-normalized value of the attribute will have the same value as the attribute value until set using the `setNonNormalizedValue` method. Also, the added attribute will be marked as specified in the XML instance document unless set otherwise using the `setSpecified` method.

  Note: If an attribute of the same name already exists, the old values for the attribute are replaced by the new values.

  Parameters:
    `attrName` - The attribute name.
    `attrType` - The attribute type. The type name is determined by the type specified for this attribute in the DTD. For example: "CDATA", "ID", "NMTOKEN", etc. However, attributes of type enumeration will have the type value specified as the pipe ('|') separated list of the enumeration values prefixed by an open parenthesis and suffixed by a close parenthesis. For example: "(true|false)".
    `attrValue` - The attribute value.
  Returns:
    Returns the attribute index.
  See Also:
    `setNonNormalizedValue(int, java.lang.String)`, `setSpecified(int, boolean)`
