      • initXPath

        public void initXPath​(Compiler compiler,
                              java.lang.String expression,
                              PrefixResolver namespaceContext)
                       throws javax.xml.transform.TransformerException
        Given an string, init an XPath object for selections, in order that a parse doesn't have to be done each time the expression is evaluated.
        Parameters:
        compiler - The compiler object.
        expression - A string conforming to the XPath grammar.
        namespaceContext - An object that is able to resolve prefixes in the XPath to namespaces.
        Throws:
        javax.xml.transform.TransformerException
      • initMatchPattern

        public void initMatchPattern​(Compiler compiler,
                                     java.lang.String expression,
                                     PrefixResolver namespaceContext)
                              throws javax.xml.transform.TransformerException
        Given an string, init an XPath object for pattern matches, in order that a parse doesn't have to be done each time the expression is evaluated.
        Parameters:
        compiler - The XPath object to be initialized.
        expression - A String representing the XPath.
        namespaceContext - An object that is able to resolve prefixes in the XPath to namespaces.
        Throws:
        javax.xml.transform.TransformerException
      • setErrorHandler

        public void setErrorHandler​(javax.xml.transform.ErrorListener handler)
        Allow an application to register an error event handler, where syntax errors will be sent. If the error listener is not set, syntax errors will be sent to System.err.
        Parameters:
        handler - Reference to error listener where syntax errors will be sent.
      • getErrorListener

        public javax.xml.transform.ErrorListener getErrorListener()
        Return the current error listener.
        Returns:
        The error listener, which should not normally be null, but may be.
