Examples of net.sf.saxon.expr.VariableReference

net.sf.saxon.expr.VariableReference
Variable reference: a reference to a variable. This may be an XSLT-defined variable, a range variable defined within the XPath expression, or a variable defined in some other static context.


    public Expression bindVariable(StructuredQName qName) throws XPathException {
        XPathVariable var = variables.get(qName);

            if (autoDeclare) {

            } else {
                throw new XPathException("Undeclared variable in XPath expression: $" + qName.getClarkName());
            }
        } else {
            return new VariableReference(var);
