Description
Class Summary | |
AnyChildNodePattern | An AnyChildNodePattern is the pattern node(), which matches any node except a root node, an attribute node, or a namespace node: in other words, any node that is the child of another node. |
AnyNodeTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
CombinedNodeTest | A CombinedNodeTest combines two nodetests using one of the operators union (=or), intersect (=and), difference (= "and not"). |
ContentTypeTest | NodeTest is an interface that enables a test of whether a node matches particular conditions. |
DocumentNodeTest | A DocumentNodeTest implements the test document-node(element(~,~)) |
IDPattern | An IDPattern is a pattern of the form id(literal) |
KeyPattern | A KeyPattern is a pattern of the form key(keyname, keyvalue) |
LocalNameTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
LocationPathPattern | A LocationPathPattern represents a path, for example of the form A/B/C... |
NamespaceTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
NameTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
NodeKindTest | NodeTest is an interface that enables a test of whether a node has a particular name and kind. |
NodeTest | A NodeTest is a simple kind of pattern that enables a context-free test of whether a node has a particular name. |
NoNodeTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
Pattern | A Pattern represents the result of parsing an XSLT pattern string. |
SubstitutionGroupTest | NodeTest is an interface that enables a test of whether a node has a particular name and type. |
UnionPattern | A pattern formed as the union (or) of two other patterns |
This package provides classes associated with XSLT pattern handling.
The principal classes are:
Pattern:
This represents an XSLT Pattern. There is a static method Pattern.make() which is
used to construct a Pattern from a String (it is a factory method rather than a
constructor, because it typically returns some subclass of Pattern according
to the syntax supplied). Subclasses of Pattern represent different kinds of pattern
such as LocationPathPattern and IDKeyPattern. What they all have in common is a match()
method, which determines whether a given node matches the pattern.
NodeTest:
This represents a NodeTest within a step of an XPathExpression. A NodeTest is a pattern
in its own right, and is used directly to implement simple patterns such as match="item"
or match="*"
. There are several subclasses of NodeTest, depending on the conditions
to be matched: node type, node name, namespace URI, and so on. The class AnyNodeTest matches any node,
while NoNodeTest matches nothing.
