问题
I am extracting article page content.
One selector, "entry": $('div.content__article-body').html().trim() gets the main article body.
This mostly comprises text paragraphs with their <p> and header tags, which is just what I want.
However, it also gets an element I don't want, which is <aside>.
How can I ensure <aside> is NOT included in the resulting text?
I have read threads on here about "not". I have tried things like ...
$('div.content__article-body').not('aside').html().trim()
$('div.content__article-body').html().not('aside').trim()
$('div.content__article-body:not(aside)').html().trim() or $('div.content__article-body:not('aside')').html().trim() - not sure.
But none of these seems to work. Am I misforming how to use "not"?
Update: Excerpt below (aside is basically a box-out within the article)...

<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>

With the .not() method, do like this, expand the selector to div.content__article-body > * so it target the div's siblings, and then loop through the result.
The usage of the child selector > allow to exclude any elements inside aside though that will also affect the other elements too, and to bring their children back in the output, use .outerHTML.
Stack snippet
$('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>And with the :not() selector.

You can try something like this:
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>Or you create another element then you remove the aside node:
var e = $('.box').html();
var newE = $('<div>'+e+'</div>');
newE.find('aside').remove();
console.log(newE.html());<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>回答3:
Try this.
$("div.content_article-body *:not(aside)");
