Interface Attributes


public interface Attributes

Interface for a list of XML attributes.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.

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 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 feature is false, access by Namespace-qualified names may not be available.

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.

Method Detail

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.


getURI

public java.lang.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

getLocalName

public java.lang.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

getQName

public java.lang.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

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".

Parameters:
index - The attribute index (zero-based).
Returns:
The attribute's type as a string, or null if the

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.

Parameters:
index - The attribute index (zero-based).
Returns:
The attribute's value as a string, or null if the

getIndex

public int getIndex(java.lang.String uri,
                    java.lang.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(java.lang.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.

getType

public java.lang.String getType(java.lang.String uri,
                                java.lang.String localName)
Look up an attribute's type by Namespace name. 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 java.lang.String getType(java.lang.String qName)
Look up an attribute's type by XML 1.0 qualified name. 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.

getValue

public java.lang.String getValue(java.lang.String uri,
                                 java.lang.String localName)
Look up an attribute's value by Namespace name. of the possible values.

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 value as a string, or null if the attribute is not in the list.

getValue

public java.lang.String getValue(java.lang.String qName)
Look up an attribute's value by XML 1.0 qualified name. of the possible values.

Parameters:
qName - The XML 1.0 qualified name.
