> Key: AMQ-2179
> URL: https://issues.apache.org/activemq/browse/AMQ-2179
> Project: ActiveMQ
> Issue Type: Bug
> Components: Selector
> Affects Versions: 5.0.0, 5.1.0, 5.2.0
> Environment: Windows XP
> Reporter: Giovani Seben
> Assignee: Dejan Bosanac
> Fix For: 5.3.0
>
> Attachments: AMQ-2179.patch

>
> Currently the XalanXPathEvaluator class will return 'true' or 'false' based
> on the existence of a node in the XML document that matches the XPath
> expression. However, XPath expressions themselves can return values of true
> or false based on a comparison criteria.
> For example, for an input message:
> {code}
> <root>
> <a key='first' num='1'/>
> <b key='second' num='2'>b</b>
> </root>
> {code}
> A consumer using an XPath selector with an expression such as:
> {code}
> XPATH '/root/b="b"'
> {code}
> should successfully select and consume the message above.
> The evaluator today would attempt to retrieve a XML node with that
> expression, but it would fail and return false since the returned value of
> the expression is a Boolean.
> The XPath Selector should be able to handle Boolean expressions.
