Examples of net.sf.saxon.expr.Expression.evaluateAsString()

net.sf.saxon.expr.Expression.evaluateAsString()

Evaluate an expression as a String. This function must only be called in contexts where it is known that the expression will return a single string (or where an empty sequence is to be treated as a zero-length string). Implementations should not attempt to convert the result to a string, other than converting () to "". This method is used mainly to evaluate expressions produced by compiling an attribute value template. @exception net.sf.saxon.trans.XPathException if any dynamic error occurs evaluating theexpression @exception ClassCastException if the result type of theexpression is not xs:string? @param context The context in which the expression is to be evaluated @return the value of the expression, evaluated in the current context.The expression must return a string or (); if the value of the expression is (), this method returns "".
