public class SAXAttrList

extends java.lang.Object

implements AttributeList, Attributes

This class implements the SAX AttributeList interface and also provides Namespace support. Applications that require Namespace support can explicitly cast any attribute list returned by an Oracle parser class to SAXAttrList and use the methods described here. It also implements Attributes (SAX 2.0) interface

This interface allows access to a list of attributes in three different ways:

1. by attribute index;
2. by Namespace-qualified name; or
3. by qualified (prefixed) name.

The list will not contain attributes that were declared #IMPLIED but not specified in the start tag. It will also not contain attributes used as Namespace declarations (xmlns*) unless the http://xml.org/sax/features/namespace-prefixes feature is set to true (it is false by default).

If the namespace-prefixes feature (see above) is false, access by qualified name may not be available; if the http://xml.org/sax/features/namespaces feature is false, access by Namespace-qualified names may not be available.

This interface replaces the now-deprecated SAX1 interface, which does not contain Namespace support. In addition to Namespace support, it adds the getIndex methods (below).

The order of attributes in the list is unspecified, and will vary from implementation to implementation.

                    java.lang.String tag,

getLength

public int getLength()

Return the number of attributes in this list.

The SAX parser may provide attributes in any arbitrary order, regardless of the order in which they were declared or specified. The number of attributes may be zero.

Specified by:

getLength in interface AttributeList

Returns:

The number of attributes in the list.

getName

public java.lang.String getName(int i)

Deprecated. as of SAX2 - Replaced by getLocalName(int i)

Return the name of an attribute in this list (by position).

The names must be unique: the SAX parser shall not include the same attribute twice. Attributes without values (those declared #IMPLIED without a value specified in the start tag) will be omitted from the list.

If the attribute name has a namespace prefix, the prefix will still be attached.

Specified by:

getName in interface AttributeList

Parameters:

i - The index of the attribute in the list (starting at 0).

Returns:

The name of the indexed attribute, or null if the index is out of range.

See Also:

getLength()

getPrefix

public java.lang.String getPrefix(int i)

Get the namespace prefix for an attribute in the list (by position)

Parameters:

i - The index of the attribute in the list.

Returns:

The namespace prefix for the attribute

getQualifiedName

public java.lang.String getQualifiedName(int i)

Deprecated. as of SAX2 - Replaced by getQName(int i)

Get the qualified name for an attribute in the list (by position)

Parameters:

i - The index of the attribute in the list.

Returns:

The qualified name for the attribute

getNamespace

public java.lang.String getNamespace(int i)

Deprecated. as of SAX2 - Replaced by getURI(int i)

Get the resolved namespace for an attribute in the list (by position)

Parameters:

i - The index of the attribute in the list.

Returns:

The resolved namespace for the attribute

getExpandedName

public java.lang.String getExpandedName(int i)

Get the expanded name for an attribute in the list (by position)

Returns:

The Namespace URI, or the empty string if none is available, or null if the index is out of range.

Since:

SAX2

getType

public java.lang.String getType(int index)

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".

Specified by:

getType in interface AttributeList

Parameters:

index - The attribute index (zero-based).

Returns:

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

See Also:

getLength()

getValue

public java.lang.String getValue(int index)

Look up an attribute's value by index.

If the attribute value is a list of tokens (IDREFS, ENTITIES, or NMTOKENS), the tokens will be concatenated into a single string with each token separated by a single space.

Specified by:

getValue in interface AttributeList

Parameters:

index - The attribute index (zero-based).

Returns:

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

See Also:
