Right. I missed that! My eyes did an auto-correct... ;) -----Original Message----- From: Brian Minchau [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 14, 2006 8:57 AM To: xalan-j-users@xml.apache.org Cc: Robert Houben Subject: RE: NullPointer in DOM2DTM.getLocalName
The line that Satoshi points out is: XPathAPI.eval( document, "/aaa/bbb/text)" ); <-- bad xpath and it sure looks like the string is "/aaa/bbb/text)" not "/aaa/bbb/text" so it is probably that trailing ')' that is causing problems. Perhaps there is no bug in Xalan-J, just a NPE rather than a good error message and 2.7.0 has improved error reporting (lets keep our fingers crossed). - Brian "Robert Houben" <[EMAIL PROTECTED] sionware.net> To <xalan-j-users@xml.apache.org> 11/14/2006 10:56 cc AM "Robert Houben" <[EMAIL PROTECTED]> Subject RE: NullPointer in DOM2DTM.getLocalName Actually, "/aaa/bbb/text" is not bad xpath, since there is nothing preventing you from having an element called "text". It just probably doesn't return any nodes. -----Original Message----- From: Satoshi Iwayama [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 14, 2006 1:14 AM To: Brian Minchau Cc: xalan-j-users@xml.apache.org Subject: Re: NullPointer in DOM2DTM.getLocalName Brian, Thank you so much. The system released 3 years ago. So, it's difficult to try 2.7.0 now. I tried to make a testcase, but I didn't get the same exception. XPathAPI.eval( null, "/aaa/bbb/text()" ); XPathAPI.eval( document, "/aaa/bbb/text)" ); <-- bad xpath XPathAPI.eval( document, "" ); XPathAPI.eval( document, null ); etc... If I get the same exception in our test environment, I'll report to JIRA.
