Vladimir commented on JXPATH-99:
--------------------------------
I've added a method, that searches nodes with specified attribute values
through the document tree, and it returnes desired node.
//-------------
// call for the above example:
findByAttr(doc, "name", "q"); // similar to //[EMAIL PROTECTED]'q']
//------------
private static Node findByAttr(Node node,String name, String s) {
if (node instanceof Element) {
Element el = (Element) node;
if (el.getAttribute(name).equals(s)) {
return el;
}
}
for (int i=0; i<node.getChildNodes().getLength(); i++) {
Node result = findByAttr(node.getChildNodes().item(i),name, s);
if (result!=null) return result;
}
return null;
}

> JXPath works incorrectly with CyberNeko HtmlParser
> --------------------------------------------------
>
> Key: JXPATH-99
> URL: https://issues.apache.org/jira/browse/JXPATH-99
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.2 Final
> Reporter: Vladimir
>
> 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 //[EMAIL PROTECTED]'q'] field
> parser.parse("http://google.com";);
> Document doc = parser.getDocument();
> // JXPATH TEST
> JXPathContext context = JXPathContext.newContext(doc);
> List nodes1 = context.selectNodes("//[EMAIL PROTECTED]'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("//[EMAIL
> PROTECTED]'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?
