I want to sent more then one expression to xpath something like this.
expression = "/BOOKLIST/BOOKS/ITEM|sum(//BOOKLIST/BOOKS/ITEM/PAGES)";
thats the problem my evaluation function expects a NodeSet and for the sum a String. Ofcourse I can split those on the' | ' character en use two return types XPathConstants.NodeSet and XPathConstants.Number. But I prefer to handle this in one expression. So I thought XPath 2.0 can to this for me.
So this is the file I used from Saxon http://kickjava.com/src/ApplyXPathJAXP.java.htm examples.
Sorry but I dont understand how I can use s9api to solve this problem..
