Can i use this tokenize function in an XPath query ......
if yes, where do i register the xalan namespace in the evaluation
context....i am evaluating the xpath expression using
XPathAPI.eval(doc,xpath);
If i give the following xpath expression //book[.=xalan:tokenize(hello ho)],
it gives an error -
Prefix must resolve to a namespace : xalan
