Constructor Detail

Parser

public Parser(StylesheetParser stylesheetParser,
              VariableBindings variables,
              FunctionLibrary library,
              NamespaceContext nsContext)

Construct a parser with the passed function library and namespace context. The function library and namespace contexts are needed for Predicate expressions in the pattern, and the namespace context are also needed by WildcardNames for matching.

Parameters:

stylesheetParser - The StylesheetParser associated with the expression. Used to get forwards-compatible mode state.

variables - The variable bindings in effect for the pattern.

library - The function library to use.

nsContext - The namespace context to use.

Method Detail

parsePattern

public Pattern parsePattern(String source,
                            boolean topLevel)
                     throws XPathParserException

Parse a string as an XSLT pattern an return the resulting object that implements the Pattern interface.

Parameters:

source - The string to parse.

topLevel - true if this is a top-level pattern (variable references not allowed)

Returns:

An object that implements the Pattern interface.

Throws:

XPathParserException
