org.xml.sax.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. See http://www.saxproject.org for further information.
This interface allows access to a list of attributes in three different ways:
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 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.
int | getIndex(String qName) | |||||
Look up the index of an attribute by XML qualified (prefixed) name. | ||||||
int | getIndex(String uri, String localName) | |||||
Look up the index of an attribute by Namespace name. | ||||||
int | getLength() | |||||
Return the number of attributes in the list. | ||||||
String | getLocalName(int index) | |||||
Look up an attribute's local name by index. | ||||||
String | getQName(int index) | |||||
Look up an attribute's XML qualified (prefixed) name by index. | ||||||
String | getType(int index) | |||||
Look up an attribute's type by index. | ||||||
String | getType(String uri, String localName) | |||||
Look up an attribute's type by Namespace name. | ||||||
String | getType(String qName) | |||||
Look up an attribute's type by XML qualified (prefixed) name. | ||||||
String | getURI(int index) | |||||
Look up an attribute's Namespace URI by index. | ||||||
String | getValue(String uri, String localName) | |||||
Look up an attribute's value by Namespace name. | ||||||
String | getValue(int index) | |||||
Look up an attribute's value by index. | ||||||
String | getValue(String qName) | |||||
Look up an attribute's value by XML qualified (prefixed) name. |
qName | The qualified (prefixed) name. |
---|
uri | The Namespace URI, or the empty string if the name has no Namespace URI. |
---|---|
localName | The attribute's local name. |
Once you know the number of attributes, you can iterate through the list.
index | The attribute index (zero-based). |
---|
index | The attribute index (zero-based). |
---|
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".
index | The attribute index (zero-based). |
---|
See getType(int) for a description of the possible types.
uri | The Namespace URI, or the empty String if the name has no Namespace URI. |
---|---|
localName | The local name of the attribute. |
See getType(int) for a description of the possible types.
qName | The XML qualified name. |
---|
index | The attribute index (zero-based). |
---|
See getValue(int) for a description of the possible values.
uri | The Namespace URI, or the empty String if the name has no Namespace URI. |
---|---|
localName | The local name of the attribute. |
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.
index | The attribute index (zero-based). |
---|
See getValue(int) for a description of the possible values.
qName | The XML qualified name. |
