      • make

        public static Expression make​(java.lang.String avt,
                                      StaticContext env)
                               throws XPathException
        Static factory method to create an AVT from an XSLT string representation. The method is also used for text value templates.
        Parameters:
        avt - the attribute value template (or TVT) as written.
        env - the static context
        Returns:
        an expression that computes the value of the attribute / content, as a string. In the case of a TVT this must be further processed to create a text node.
        Throws:
        XPathException
