weblogic.apache.xerces.xni
Interface XMLAttributes

All Known Implementing Classes:

DOMNormalizer.XMLAttributesProxy, XMLAttributesImpl

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 propogated 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)

removeAllAttributes

public void removeAllAttributes()

Removes all of the attributes. This method will also remove all entities associated to the attributes.

removeAttributeAt

public void removeAttributeAt(int attrIndex)

Removes the attribute at the specified index.

Note: This operation changes the indexes of all attributes following the attribute at the specified index.

Parameters:

attrIndex - The attribute index.

getLength

public int getLength()

Returns the number of attributes in the list.

Once you know the number of attributes, you can iterate through the list.

Look up an attribute's type by index.

The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).

If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommentation (clause 3.3.3, "Attribute-Value Normalization").

For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".

Parameters:

index - The attribute index (zero-based).

Returns:

The attribute's type as a string, or null if the index is out of range.
