Michele Vivoda created JXPATH-161:
-------------------------------------
Summary: negative index in xpath expression
Key: JXPATH-161
URL: https://issues.apache.org/jira/browse/JXPATH-161
Project: Commons JXPath
Issue Type: Bug
Affects Versions: 1.3, 1.4
Reporter: Michele Vivoda
Priority: Minor
JXPath seems to handle incorrectly negative indexes in XPath expressions
Given xml <root><a>1<a></root> and xpath "/root/a[-1]"
Xalan and Saxon match no node
JXPath matches <a>.
The same happens also for expressions "/root/a[-2]" and "/root/a[0]" (in XPath
index starts with one)
This problem does not affect xpath on beans, that seems to work correctly, but
is present when performing xpath on DOM.
