Question

我有这个HTML模板：

<div class="item">
<span class="light">Date</span>
<a class="link" href="">2018</a>
(4pop)
</div>

<div class="item">
<span class="light">From</span>
<span>
<a class="link" href="" title="Bob" itemprop="url"><span itemprop="name">Bob</span></a>,
</span>
<span>
<a class="link" href="" title="Peter" itemprop="url"><span itemprop="name">Peter</span></a>
</span>
</div>

<div class="item">
<span class="light">For</span>
<a class="link" href="">Bak</a>,
<a class="link" href="">Cam</a>,
<a class="link" href="">Oli</a>
</div>

<div class="item">
<span class="light">Nat</span>
<a class="link" href="">Cool</a>
</div>
</div>

还有我的Javascript代码：

var doc = new DOMParser().parseFromString(HTMLContent,'text/html');
var infos = doc.evaluate('//div[@class="item"]/span[1]', doc, null, XPathResult.ANY_TYPE, null);

var nodes = [];
for(var node = infos.iterateNext(); node; node = infos.iterateNext()) {
nodes.push(node);
console.log(node.textContent);

// Until here, all things works well ! Except the code from here:
var nodde = node.nextElementSibling.attributes;

nodde.forEach(function(item){
console.log(item);
});
}

我的目标是获取每个类别的相应值，例如：

Date = 2018, (4pop)
From = Bob, Peter
For = Bak, Cam, Oli
Nat = Cool

我尝试迭代：node.nextElementSibling.attributes，但没有成功！

请问有没有办法得到预期的结果？

首选HTML文档对象模型DOM，因为它更容易。 XPATH面向更严格的XML文档。

使用JavaScript，您将获得类似以下内容的数据：

var users = document.querySelectorAll('[itemprop=name]').textContent;
console.log(users);

从Javascript中的XPATH获取更多值
