pointers
[ https://issues.apache.org/jira/browse/JXPATH-155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15020353#comment-15020353 ]

------------------------------------
Could you provide a small test case (JUnit test case)?
> iteratePointers give the wrong pointers
> ---------------------------------------
>
> Key: JXPATH-155
> URL: https://issues.apache.org/jira/browse/JXPATH-155
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.3
> Environment: jdk 1.5
> Reporter: Martin Busch
>
> I have a xml structur like these:
> {code:xml}
> <Request>
> <Tarifierung>
> <Verkaufsprodukt>
> <Produkt>
> <Kondition>
> <Wert>2</Wert>
> <Werteinheit>10</Werteinheit>
> </Kondition>
> <Kondition>
> <Wert>3</Wert>
> <Werteinheit>10</Werteinheit>
> </Kondition>
> <Kondition>
> <Wert>6</Wert>
> <Werteinheit>10</Werteinheit>
> </Kondition>
> <Kondition>
> <Wert>16</Wert>
> <Werteinheit>10</Werteinheit>
> </Kondition>
> </Produkt>
> </Verkaufsprodukt>
> </Tarifierung>
> </Request>
> {code}
> I get an iterator for the "Kondtion" tags:
> {code:java}
> JXPathContext context = JXPathContext.newContext(in);
> Iterator<Pointer> it_konditionen = (Iterator<Pointer>) context.iteratePointers("/request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition");
> while (it_konditionen != null && it_konditionen.hasNext()) {
> Pointer p = it_konditionen.next();
> System.out.println(p);
> }
> {code}
> The output to System.out looks like:
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[2]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[3]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[4]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[1]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[2]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[3]
> /request/tarifierung/verkaufsprodukt[1]/produkt[1]/kondition[4]
> As we can see it start with [2] (which is not the problem) but it iterates over 2-4 twice! And this IS a problem.
> Very strange is that the call of "it_konditionen.hasNext()" increase the iterator one step.
> Best regards
