----------------------------------------
See my suggested patch at JXPATH-189.
> Pipe not working correctly in xpaths
> ------------------------------------
>
> Key: JXPATH-176
> URL: https://issues.apache.org/jira/browse/JXPATH-176
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.3
> Environment: Windows 7 Enterprise, JDK 1.8.0
> Reporter: Martin Xarx
> Priority: Major
>
> It seems to me that "pipes" do not work reliably in JXPath, or at least not
> for java containers:
> xpath: size(x/name|name), result: 0
> xpath: x/name|name, result: ROOT name
> xpath: (x/name|name), result: ROOT name
> while there is:
> xpath: size(name), result: 1
> xpath: name, result: ROOT name
> xpath: (name), result: ROOT name
> xpath: size(x/name), result: 1
> xpath: x/name, result: X name
> xpath: (x/name), result: X name
> The data model is like this:
> {
> "name" : "ROOT name",
> "x" : {
> "name" : "X name"
> }
> }
> and the context is set to the root node. I'm using the following code:
> JXPathContext xpathContext = JXPathContext.newContext(root);
> Pointer p = contextContext.getPointer(xpath);
> return p.getNode();
