Constructor Detail

AttributeList2Attributes

public AttributeList2Attributes(org.xml.sax.AttributeList atts)

Creates a new AttributeList2Attributes instance with the given AttributeList

Parameters:

atts - the AttributeList to wrap

Method Detail

getAttributeList

public org.xml.sax.AttributeList getAttributeList()

Returns the AttributeList being "wrapped" by this AttributeList2Attributes instance.

Returns:

the AttributeList being "wrapped".

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.

Specified by:

getLength in interface org.xml.sax.Attributes

Returns:

The number of attributes in the list.

getURI

public java.lang.String getURI(int index)

Look up an attribute's Namespace URI by index.

Specified by:

getURI in interface org.xml.sax.Attributes

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:

getLength()

getLocalName

public java.lang.String getLocalName(int index)

Look up an attribute's local name by index.

Specified by:

getLocalName in interface org.xml.sax.Attributes

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:

getLength()

getQName

public java.lang.String getQName(int index)

Look up an attribute's XML 1.0 qualified name by index.

Specified by:

getQName in interface org.xml.sax.Attributes

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:

getLength()

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 org.xml.sax.Attributes

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 org.xml.sax.Attributes

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:

getLength()

getIndex
