Shruti --
I think you'd be better off by implementing an XSLT extension function
rather than changing the core of XalanJ.
Have a look at http://xml.apache.org/xalan-j/extensions.html and at the
XSLT Recommendation itself.
You'd also find some good examples in org.apache.xalan.lib.Extensions.
It seems like you might be able to use the tokenize extension
(http://xml.apache.org/xalan-j/extensionslib.html#tokenize), already
supplied by XalanJ, to accomplish what you want:
//book[. = xalan:tokenize("hello ho")]
or something like that.
