    "entry": $('div.content__article-body').html().trim() <p> 但是,它也得到了一个我不想要的元素,也就是 <aside> <旁白>

    我尝试过… 

    $('div.content__article-body').not('aside').html().trim()

$('div.content__article-body').html().not('aside').trim()

    $('div.content__article-body:not(aside)').html().trim() $('div.content__article-body:not('aside')').html().trim() -不确定。

    更新 aside

<p>A wise man once <a href="http://www.quora.com/Who-originally-suggested-that-if-youre-not-paying-for-the-product-you-are-the-product" rel="nofollow" data-link-name="in body link" class="u-underline">said</a>: “If you’re not paying for it, you’re the product.” That’s what is happening in the magazine world, as <a href="https://www.theguardian.com/media/2015/jul/06/nme-to-go-free-with-larger-circulation" data-link-name="in body link" class="u-underline">NME abandons its cover price</a> after 63 years, to go free.<br></p>
<p>In doing so, the title is turning its readers from customers in to advertiser targets.

<h2>1. Know your predicament</h2>
<p>It would be nice to say the switch to free comes either out of benevolence or out of a market opportunity. The reality is, operators invariably flick the switch under external pressure of a poor business outlook – no amount of dressing up as a “bold relaunch” can change that.</p>
<p>NME’s circulation was falling by <a href="https://www.theguardian.com/media/2014/feb/13/nme-relaunch-sales-slide-ipc-media" data-link-name="in body link" class="u-underline">around a fifth annually</a>. The Evening Standard was frustrated to find itself far behind national dailies on ad planners’ schedules, locking it out of big brand bucks, according to someone familiar with the strategy to switch.</p>
<p>The Village Voice dropped its cover charge in 1996 after being eaten into by rival New York Press being given away in green sidewalk boxes, while Hong Kong’s Standard newspaper was forced to act when the government removed a decree that listed companies must buy classified ads in newspapers. But the key – as anyone who has heard the “<a href="https://en.wikipedia.org/wiki/Boiling_frog" rel="nofollow" data-link-name="in body link" class="u-underline">boiling frog</a>” allegory will know – is to recognise when it is your time to change tack.</p>

    与 .not() 方法,执行如下操作,将选择器扩展到 div.content__article-body > * 所以它的目标是 div 的兄弟姐妹,然后循环遍历结果。

    子选择器的用法 > 允许排除内部的任何元素 aside 尽管这也会影响其他元素,并使其子元素返回到输出中,但是使用 .outerHTML .

    堆栈段 

    $('div.content__article-body > *').not('aside').each( function( index, value ) {
  console.log( value.outerHTML );
});
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="content__article-body">

    <p>some paragraph <span>some span</span></p>

    <div>some div</div>

    <aside>an aside <div>some div in aside</div></aside>

</div>

    和 :not() 选择器。

    堆栈段 

    $('div.content__article-body > *:not(aside)').each( function( index, value ) {
  console.log( value.outerHTML );
});
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="content__article-body">

  <p>some paragraph <span>some span</span></p>

  <div>some div</div>

  <aside>an aside <div>some div in aside</div></aside>

</div>

    var e = $('.box').html();
console.log(e);

var subStr = e.match("<aside>(.*?)</aside>");
var r = e.replace(subStr[0], "");

console.log(r);
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
  Some text here
  <p>More text here</p>
  <aside>this is an <span>aside</span></aside>
</div>

    var e = $('.box').html();
var newE = $('<div>'+e+'</div>');
newE.find('aside').remove();
console.log(newE.html());
