Subject [jira] Updated: (JXPATH-12) Descendant or self axis does not work correctly at root node
Date Thu, 11 Sep 2008 16:19:50 GMT

Murty Gurajada updated JXPATH-12:
---------------------------------

    Attachment: xpathEvalBug.zip

Attached zip file contains a package with the JUnit test org.apache.commons.jxpath.test.TestDescOrSelfEval.java
that I ran in Java 1.5 to demo a bug when an Element node context is passed to evaluate an
xpath expression starting with '//'

>    Affects Versions: 1.2 Final
>         Environment: Operating System: other
> Platform: Other

> Given the following XML document: <root id="1234"/>
> and the XPath: //root/@id/text().
> JXPath returns null instead of "1234".
> JXPathContext context = JXPathContext.newContext(doc);
> assertEquals(value, context.selectSingleNode("//root/@id/text()"));
> The attached JUnit test highlights the problem. It seems that JXPath does not
> find the root node if it is accessed with the axis descendant-or-self.
