| org.xml.sax.Attributes
| Attributes | | public interface Attributes (Code) | | Interface for a list of XML attributes.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
See http://www.saxproject.org
for further information.
This interface allows access to a list of attributes in
three different ways:
- by attribute index;
- by Namespace-qualified name; or
- 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).
Because SAX2 conforms to the original "Namespaces in XML"
recommendation, it normally does not
give namespace declaration attributes a namespace URI.
Some SAX2 parsers may support using an optional feature flag
(http://xml.org/sax/features/xmlns-uris) to request
that those attributes be given URIs, conforming to a later
backwards-incompatible revision of that recommendation. (The
attribute's "local name" will be the prefix, or "xmlns" when
defining a default element namespace.) For portability, handler
code should always resolve that conflict, rather than requiring
parsers that can change the setting of that feature flag.
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
org.xml.sax.AttributeList AttributeList 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.

| Method Summary | |
| public int | getIndex(String uri, String localName)
Look up the index of an attribute by Namespace name.
Parameters:
uri - The Namespace URI, or the empty string ifthe name has no Namespace URI.
Parameters:
localName - The attribute's local name. | | public int | getIndex(String qName)
Look up the index of an attribute by XML qualified (prefixed) name.
Parameters:
qName - The qualified (prefixed) name. | | abstract public int | getLength()
Return the number of attributes in the list. | | abstract public String | getLocalName(int index)
Look up an attribute's local name by index.
Parameters:
index - The attribute index (zero-based). | | abstract public String | getQName(int index)
Look up an attribute's XML qualified (prefixed) name by index.
Parameters:
index - The attribute index (zero-based). | | abstract 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 Recommendation
(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). | | abstract public String | getType(String uri, String localName)
Look up an attribute's type by Namespace name.
See
Attributes.getType(int) getType(int) for a description
of the possible types.
Parameters:
uri - The Namespace URI, or the empty String if thename has no Namespace URI.
Parameters:
localName - The local name of the attribute. | | abstract public String | getType(String qName)
Look up an attribute's type by XML qualified (prefixed) name.
See
Attributes.getType(int) getType(int) for a description
of the possible types.
Parameters:
qName - The XML qualified name. | | abstract public String | getURI(int index)
Look up an attribute's Namespace URI by index.
Parameters:
index - The attribute index (zero-based). | | abstract 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). | | abstract public String | getValue(String uri, String localName)
Look up an attribute's value by Namespace name.
See
Attributes.getValue(int) getValue(int) for a description
of the possible values.
Parameters:
uri - The Namespace URI, or the empty String if thename has no Namespace URI.
Parameters:
localName - The local name of the attribute. | | abstract public String | getValue(String qName)
Look up an attribute's value by XML qualified (prefixed) name.
See
Attributes.getValue(int) getValue(int) for a description
of the possible values.
Parameters:
qName - The XML qualified name. |
| getIndex | | public int getIndex(String uri, String localName)(Code) | | Look up the index of an attribute by Namespace name.
Parameters:
uri - The Namespace URI, or the empty string ifthe name has no Namespace URI.
Parameters:

| getLocalName | | abstract public String getLocalName(int index)(Code) | | Look up an attribute's local name by index.
Parameters:
index - The attribute index (zero-based). The local name, or the empty string if Namespaceprocessing is not being performed, or nullif the index is out of range.
