 net.sf.saxon.sxpath.XPathEvaluator
| XPathEvaluator | | public class XPathEvaluator (Code) | | This is a cut-down version of the XPathEvaluator in the net.sf.saxon.xpath package. It provides
much of the same functionality, but without any dependencies on the JAXP 1.3 interfaces, which
are not available in JDK 1.4. The main restrictions are that it does not support mechanisms for
defining variables or functions.

| XPathEvaluator | | public XPathEvaluator()(Code) | | Default constructor. Creates an XPathEvaluator with a default configuration and name pool.
|
| XPathEvaluator | | public XPathEvaluator(Configuration config)(Code) | | Construct an XPathEvaluator with a specified configuration.
Parameters:
config - the configuration to be used |
| build | | public NodeInfo build(Source source) throws XPathException(Code) | | Build a source document.
Parameters:
source - a JAXP Source object. This may be any implementation of Source that Saxon recognizes:not only the standard kinds of source such as StreamSource, SAXSource, and DOMSource, but also forexample a JDOM or XOM DocumentWrapper. the NodeInfo representing the root of the constructed tree.
throws:
XPathException - if, for example, XML parsing fails. |
| createExpression | | public XPathExpression createExpression(String expression) throws XPathException(Code) | | Prepare an XPath expression for subsequent evaluation.
Parameters:
expression - The XPath expression to be evaluated, supplied as a string. an XPathExpression object representing the prepared expression
throws:
XPathException - if the syntax of the expression is wrong, or if it references namespaces,variables, or functions that have not been declared. |
| getStaticContext | | public IndependentContext getStaticContext()(Code) | | Get the current static context. This will always return a value; if no static context has been
supplied by the user, the system creates its own.
|
| main | | public static void main(String[] args) throws Exception(Code) | | A simple command-line interface for the XPathEvaluator (not documented).
First parameter is the filename containing the source document, second
parameter is the XPath expression.
|
| setNamespaceResolver | | public void setNamespaceResolver(NamespaceResolver namespaceContext)(Code) | | Set the external namespace resolver to be used. This overrides any namespaces declared directly
using declareNamespace on the staticContext object
Parameters:
namespaceContext - The namespace context |
| setStaticContext | | public void setStaticContext(IndependentContext context)(Code) | | Set the static context for compiling XPath expressions. This provides control over the
environment in which the expression is compiled, for example it allows namespace prefixes to
be declared, variables to be bound and functions to be defined. For most purposes, the static
context can be defined by providing and tailoring an instance of the IndependentContext class.
Until this method is called, a default static context is used, in which no namespaces are defined
other than the standard ones (xml, xslt, and saxon), and no variables or functions (other than the
core XPath functions) are available.
|
| setStripSpace | | public void setStripSpace(boolean strip)(Code) | | Indicate whether all whitespace text nodes in the source document are to be
removed.
Parameters:
strip - True if all whitespace text nodes are to be stripped from the source document,false otherwise. The default if the method is not called is false. |
