Matt Benson commented on JXPATH-99:
-----------------------------------

One more suggestion here:  I noticed this FAQ on the Neko site:

> I don't know exactly where is the bug. I have an idea, that CyberNeko html parser creates
some wired w3c DOM representation of html file, and that is the cause. Here is a code sample:
> // ---------------------------
>        // create CyberNeko html parser 
>         DOMParser parser = new DOMParser();
>         // this page does have //input[@name='q'] field
>         parser.parse("http://google.com");
>         Document doc = parser.getDocument();
>         // JXPATH TEST
>         JXPathContext context = JXPathContext.newContext(doc);
>         List nodes1 = context.selectNodes("//input[@name='q']"); // ERROR IS HERE: call
returns nothing, must return 1 node
>         List nodes2 = context.selectNodes("//*"); // returnes 78 nodes
>         System.out.println(nodes1.toString());
>         System.out.println(nodes2.toString());
>         // XPathFactory TEST  ( for comparison )
>         // error, returns nothing
>         Object list1 = XPathFactory.newInstance().newXPath().compile("//input[@name='q']").evaluate(doc,
XPathConstants.NODESET);
>         // returns 79 nodes
>         Object list2 = XPathFactory.newInstance().newXPath().compile("//*").evaluate(doc,
XPathConstants.NODESET);
>         System.out.println(list1);
>         System.out.println(list2);
> // -----------------------------------
> Is it possible to fix this problem inside JXPath? Or is it only html parser problem?
