[jira] Commented: (JXPATH-86) Children returned instead of self for
arrays when using . selector
[ https://issues.apache.org/jira/browse/JXPATH-86?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12498479 ]
Matt Benson commented on JXPATH-86:
-----------------------------------
Some of this report is probably valid, but I remain skeptical on some things. Your complaints about *, for example, are invalid because JXPath, by design, returns only the first matching value from getValue() and getPointer(). You should find that e.g. iterate(), iteratePointers(), and/or selectNodes() would work for you here. The only "correctly incorrect" thing I see in this bugrep is:
/array/. -> /.[@name='array'][1]

> The . selector should always return the context node, and the * selector should return child elements. However, this doesn't work for arrays:
> JXPathContext context = JXPathContext.newContext(new HashMap());
> context.setValue("array", new String[] {"one", "two", "three"});
> context.setValue("array2", new String[][] { {"a", "b"}, {"c", "d"}});
> context.setValue("person", new Person("Bob", 25));
> String[] paths = {"/array", "/array/.", "/array/*", "/person", "/person/.", "/person/*"};
> for(int i = 0; i < paths.length; i++) {
> Pointer pointer = context.getPointer(paths[i]);
> System.out.println(pointer.asPath());
> Object value = context.getValue(paths[i]);
> System.out.println(value);
> System.out.println();
> }
> This produces the following output:
> /.[@name='array']
> [Ljava.lang.String;@59b659b6
> /.[@name='array'][1]
> one
> /.[@name='array'][1]/bytes[1]
> 111
> /.[@name='person']
> net.cts.jxpathserializer.Person@760076
> /.[@name='person']
> net.cts.jxpathserializer.Person@760076
> /.[@name='person']/age
> 25
