I am new to jxpath, so please forgive my improper use of terminology or other
ignorance.
I have a data structure consisting of nested maps and lists. I am able to
iterate over these elements with ease as long as I stick to a path-based xpaths
("key1/key2/key3"), however, this approach fails if my keys contain illegal
characters such as spaces. To solve this problem, I translate these xpaths
into predicate-based xpaths ("./[...@name='key 1']...@name='key
2']...@name='key 3']). This solves the illegal-character problem but breaks
the ability to iterate over lists. My impulse is to revert to path-based
xpaths and create a map-wrapper exposes url-encoded keys in its API, but it
occurs to be that there must be an easier way. Any suggestions? Is there a
way to use the @name= notation while retaining the ability to iterate? I am
hoping for some kind of [*] delimiter to put in the xpath.
List<Map> records = new ArrayList<Map>();
Map record = new HashMap();
records.add(record);
List<Map> families = new ArrayList<Map>();
record.put("Families", families);
Map family = new HashMap();
families.add(family);
family.put("Wife", "Karen");
JXPathContext rootContext = JXPathContext.newContext(dataMap);
String xpath = "Families/Wife";
assertNotNull("Blank Wife", rootContext.getValue(xpath));
Iterator pointerIterator = rootContext.iteratePointers(xpath);
assertTrue("Missing next Wife.", pointerIterator.hasNext());
xpath = "....@name = 'Families']...@name = 'Wife']";
assertNotNull("Blank encoded Wife", rootContext.getValue(xpath));
pointerIterator = rootContext.iteratePointers(xpath);
assertTrue("Missing next encoded Wife.", pointerIterator.hasNext()); //
Fails here
Thanks in advance.
