[jxpath] matching
hi
I want to know whether a given object (or a Pointer?) matches an xpath
expression. Let's say I have the following code:
Root root = ...;
JXPathContext context = JXPathContext.newContext(root);
Child child = root.getChild(2);
...
if (context.matches(child, "/child")) {
// "/child" matches the given object 'child'
}
(It's just an example. The method matches would probably be located
somehwere else (Pointer?).)
What I want to achieve is something similar as CSS does in HTML. That
is, I want to assign attributes to certain parts of a tree (in my case,
an object tree). Instead of using CSS selectors (that are not very
intuitive...) I want to use xpath location paths as selectors.
So in my case, I want to have a stylesheet that looks like:
/child {
foo: bar;
}
This would assign the foo attribute the value 'bar' to every 'child'.
Is this possible at the moment? I did not find anything. Have I missed
something? I'm not too familiar with jxpath so I don't see how this
could fit in. Any ideas?
Simon
