使用正则表达式对页面上的所有链接进行JavaScript

Question

I'm trying to extract all links on a web page that has the following markup:

<a href="/item/0/100">0</a>
<a href="/item/1/100">2</a>
<a href="/item/2/100">3</a>
<a href="/item/3/100">4</a>
<a href="/item/4/100">5</a>

Basically returning all the /item... paths. I have the dom object that contains this. Any idea how to do this?

Thanks!

EDIT: Using jQuery with Map returns (truncated)

    http:undefined
    { '0': '/item/200/13/0',
      '1': '/item/200/1/0',
      '2': '/item/200/4/0',
      '3': '/item/200/5/0',
      '4': '/item/200/11/0',
      length: 4,
      prevObject: 
       { '0': 
          { _ownerDocument: [Object],
            _childNodes: [Object],
            _attributes: [Object],
            _nodeName: 'a',
            _childrenList: null,
            _version: 3,
            _nodeValue: null,
            _parentNode: [Object],
            _readonly: false,
            _tagName: 'a',
            _created: true,
            _attached: true,
            _attachedToDocument: true },
         '1': 
...

Newer browsers:

var links = document.querySelectorAll('a[href^="/item/"]');

Older browsers:

var links = [];
var elements = document.getElementsByTagName('a');

for (var i = 0; i < elements.length; i++) {
    var a = elements[i];

    if (a.getAttribute('href').indexOf('/item/') === 0) {
        links.push(a);
    }
}
