Hi, is it possible to limit the results of a selector? Say I have a very large html page, and there are 10000 items on the page. If I only want the first ten, is there a way to limit the loop in cheerio? I know I can mostly achieve what I am trying to do within the querySelector:
cheerio.load(largeHtmlString)
const items = []
$('ul > li:nth-child(-n+10)').text((i, text) => items.push(text))but this seems slightly less clear, and not applicable to all situations. Is it possible to give a "max" to cheerio?

Hello Everyone, I am trying to use cheerio in a nodejs application and trying to parse a document to get a structure that I can use to index documents with algolia. I am allowing the developer consuming this to pass in a structure such as h1 h3 p, or h1 h2 h3 p but this will be dynamic. I am then trying to get the elements and create json objects which will be passed to algolia for indexing. Below is a sample html structure and how the json objects are created
<h1>Article Title</h1>
<h3>Section Title</h3>
<p>Content</p>
<h3>Section Two</h3>
<p>Content 2</p>
<h3>Section Three</h3>
<p>Content 3</p>
<h1>Secondary Title</h1>
<p>Secondary Content</p>so for the options.structure I would pass in h1 h3 p, this would then create the following structures to pass to algolia
{
"link":"path/article#article-title",
"importance":0,
"objectID":"path/article#article-title-816d21744be4034a4bfa3323722024b4"
"h1":"Article Title",
}
{
"link":"path/article#section-title",
"importance":3,
"objectID":"path/article#section-title-816d21744be4034a4bfa3323722024b4",
"h1":"Article Title",
"h3":"Section Title"
}
{
"link":"path/article#section-title-p0",
"importance":5,
"objectID":"path/article#section-title-p0-ae5e3efcdddc387616bbc5b1e5b1b134",
"h1":"Article Title",
"h3":"Section Title",
"p":"Content"
}
{
"link":"path/article#section-two”,
"importance":3,
"objectID":"path/article#section-two-816d21744be4034a4bfa3323722024b4",
"h1":"Article Title",
"h3":"Section Two”
}
{
"link":"path/article#section-two-p0",
"importance":5,
"objectID":"path/article#section-two-p0-ae5e3efcdddc387616bbc5b1e5b1b134",
"h1":"Article Title",
"h3":"Section Two”,
"p":"Content 2”
}
{
"link":"path/article#section-three”,
"importance":3,
"objectID":"path/article#section-three-816d21744be4034a4bfa3323722024b4",
"h1":"Article Title",
"h3":"Section Three”
}
{
"link":"path/article#section-three-p0",
"importance":5,
"objectID":"path/article-title#section-three-p0-ae5e3efcdddc387616bbc5b1e5b1b134",
"h1":"Article Title",
"h3":"Section Three”,
"p":"Content 3”
}
{
"link":"path/article#secondary-title",
"importance":0,
"objectID":"path/article#secondary-title-816d21744be4034a4bfa3323722024b4"
"h1”:”Secondary Title",
}
{
"link":"path/article#secondary-title-p0”,
"importance”:4,
"objectID":"path/article#secondary-title-p0-816d21744be4034a4bfa3323722024b4"
"h1”:”Secondary Title",
"p”:”Secondary Content”,
}Now this structure would have to be dynamic meaning rather than the above they could pass in h1 h2 h3 h4 p and it should be parsed accordingly.
There could also be content under h1 such as <h1>Title</h1><p>Content</p> and this would receive a different importance as seen in the last example above.
The trouble I am having is how can I select all paragraphs under each tag in the structure. I know I can get all p tags under h1 and that will return them all but it will not let me know which h1 the p’s belong to, etc.
I am following this article trying to replicate this using cheerio.
