Re: xalan extensions - get the result tree

Hi Mukul,
I found a way to get the processed result as a string and count it:

function count(context, elem){
	transf = context.getTransformer();
	count=transf.transformToString(elem).length();

	transf.executeChildTemplates(elem,true);
	return "";
}

Is it possible to add an attribute to the parent node?
Thanks
Jan
