Constructor Detail

AttributeList2Attributes

public AttributeList2Attributes(AttributeList atts)
Creates a new AttributeList2Attributes instance with the given AttributeList

Parameters: atts the AttributeList to wrap

Method Detail

getAttributeList

public AttributeList getAttributeList()
Returns the AttributeList being "wrapped" by this AttributeList2Attributes instance.

Returns: the AttributeList being "wrapped".

getIndex

public int getIndex(String uri, String localPart)
Look up the index of an attribute by Namespace name.

Parameters: uri The Namespace URI, or the empty string if the name has no Namespace URI. localName The attribute's local name.

Returns: The index of the attribute, or -1 if it does not appear in the list.

getIndex

public int getIndex(String qName)
Look up the index of an attribute by XML 1.0 qualified name.

Parameters: qName The qualified (prefixed) name.

Returns: The index of the attribute, or -1 if it does not appear in the list.

getLength

public int getLength()
Return the number of attributes in the list.

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

Returns: The number of attributes in the list.

getLocalName

public String getLocalName(int index)
Look up an attribute's local name by index.

Parameters: index The attribute index (zero-based).

Returns: The local name, or the empty string if Namespace processing is not being performed, or null if the index is out of range.

See Also: AttributeList2Attributes

getQName

public String getQName(int index)
Look up an attribute's XML 1.0 qualified name by index.

Parameters: index The attribute index (zero-based).

Returns: The XML 1.0 qualified name, or the empty string if none is available, or null if the index is out of range.

See Also: AttributeList2Attributes

getType

public 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".

Parameters: index The attribute index (zero-based).

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

getType

public String getType(String uri, String localName)
Look up an attribute's type by Namespace name.

See getType(int) for a description of the possible types.

Parameters: uri The Namespace URI, or the empty String if the name has no Namespace URI. localName The local name of the attribute.

Returns: The attribute type as a string, or null if the attribute is not in the list or if Namespace processing is not being performed.

getType

public String getType(String qName)
Look up an attribute's type by XML 1.0 qualified name.

See getType(int) for a description of the possible types.

Parameters: qName The XML 1.0 qualified name.

Returns: The attribute type as a string, or null if the attribute is not in the list or if qualified names are not available.

getURI

public String getURI(int index)
Look up an attribute's Namespace URI by index.

Parameters: index The attribute index (zero-based).

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

See Also: AttributeList2Attributes

getValue

public 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.

Parameters: index The attribute index (zero-based).

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