Examples of org.apache.xpath.compiler.Compiler

org.apache.xpath.compiler.Compiler
An instance of this class compiles an XPath string expression into a Expression object. This class compiles the string into a sequence of operation codes (op map) and then builds from that into an Expression tree.

      errorListener = new org.apache.xml.utils.DefaultErrorHandler();
    
    m_patternString = exprString;


    XPathParser parser = new XPathParser(errorListener, locator);
    Compiler compiler = new Compiler(errorListener, locator);


    if (SELECT == type)
      parser.initXPath(compiler, exprString, prefixResolver);
    else if (MATCH == type)
      parser.initMatchPattern(compiler, exprString, prefixResolver);
    else
      throw new RuntimeException(XSLMessages.createXPATHMessage(XPATHErrorResources.ER_CANNOT_DEAL_XPATH_TYPE, new Object[]{Integer.toString(type)})); //"Can not deal with XPath type: " + type);


    // System.out.println("----------------");
    Expression expr = compiler.compile(0);


    // System.out.println("expr: "+expr);
    this.setExpression(expr);
    
    if((null != locator) && locator instanceof ExpressionNode)
