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 '//'
> Descendant or self axis does not work correctly at root node
> ------------------------------------------------------------
>
> Key: JXPATH-12
> URL: https://issues.apache.org/jira/browse/JXPATH-12
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.2 Final
> Environment: Operating System: other
> Platform: Other
> Reporter: Simon Raess
> Fix For: 1.3
>
> Attachments: DescendantOrSelfTest.java, patch.jxpath-12.txt,
> xpathEvalBug.zip
>
>
> 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.
