[jira] Resolved: (JXPATH-99) JXPath works incorrectly with
CyberNeko HtmlParser
[ https://issues.apache.org/jira/browse/JXPATH-99?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matt Benson resolved JXPATH-99.
-------------------------------
Resolution: Invalid
The problem here is that the Neko parser you are using specifies a particular Xerces HTML document implementation that converts all element names to upper case. Thus in your example you should have been searching for //INPUT[@name='q'] . As for your followup additional method to search by attribute only that seems to be equivalent to e.g. //*[@name='q'] .

> 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?
