Representation of a qualified XML name.
This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.
A "triple" in the libSBML XML layer encapsulates the notion of qualified name, meaning an element name or an attribute name with an optional namespace qualifier. An XMLTriple instance carries up to three data items:
The name of the attribute or element; that is, the attribute name as it appears in an XML document or data stream;
The XML namespace prefix (if any) of the attribute. For example, in the following fragment of XML, the namespace prefix is the string mysim
and it appears on both the element someelement
and the attribute attribA
. When both the element and the attribute are stored as XMLTriple objects, their prefix is mysim
.
<mysim:someelement mysim:attribA="value" />
The XML namespace URI with which the prefix is associated. In XML, every namespace used must be declared and mapped to a URI.
XMLTriple objects are the lowest-level data item in the XML layer of libSBML. Other objects such as XMLToken make use of XMLTriple objects.
