Description
I am using the S9API to evaluate XPath expressions, like this:
Processor processor = new Processor();
XPathCompiler compiler = processor.newXPathCompiler();
XPathExecutable executable = compiler.compile(XPATH_EXPRESSION);
XPathSelector selector = executable.load();
selector.setContextItem(node);
selector.setURIResolver(URI_RESOLVER);
selector.evaluate();
The resolver URI_RESOLVER is used to resolve URLs in function fn:doc(), for instance:
doc("http://www.bbc.co.uk/news_sitemap.xml")//*
So far so good.
Now, i am trying to parse JSON expressions. This works:
...
XPathExecutable executable = compiler.compile("json-doc('http://api.open-notify.org/iss-now.json')" + JSON_EXPRESSION);
...
I have two questions:
- The resolver URI_RESOLVER is not used to resolve URLs in fn:json-doc(). Is this a bug?
- My solution works but it is a bit clumsy: is there a way to evaluate JSON expressions without the json-doc() function? I tried ParseJsonFn.parse(), but the resulting Item was not accepted by setContextItem().
