[jira] [Updated] (COLLECTIONS-322) Adds a Collections wrapper around the w3c NodeList

AD_LB (Jira)

     [ https://issues.apache.org/jira/browse/COLLECTIONS-322?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Vahrst updated COLLECTIONS-322:
--------------------------------------

    Attachment: nodelistAsIterable.patch

I implemented the suggested Utility methods, which provide an Iterable for a given NodeList or ParentNode. See nodelistAsIterable.patch

I chose IteratorUtils as implementation class, I found this class matching best  for the new services.

The util methods now allow easy iteration over org.w3c.NodeLists or ChildNodes of a given parent node:

{code}
for(Node childNode : IteratorUtils.asIterable(parentNode){
  ... do something;
}

{code}

> org.w3c.dom.NodeList is defined as an "abstract collection of Nodes" and java.util.List is defined as "An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.". It seemed similar enough, so I did an implementation of the useful methods, while throwing the appropriate exception when the method wouldn't make sense.
