Example of parsing an HTML string to grab all h1 elements:

Add-Type -Path "path\to\AngleSharp.dll"

$html = @"
<html>
<head><title>Test</title></head>
<body>
    <h1>Heading 1</h1>
    <h1>Heading 2</h1>
    <p>Hello, world!</p>
</body>
</html>
"@

$parser = New-Object AngleSharp.Html.Parser.HtmlParser
$document = $parser.ParseDocument($html)
$headings = $document.QuerySelectorAll("h1")

foreach ($h in $headings) {
    Write-Output $h.TextContent
}

Sample output:

Heading 1
Heading 2

Deep Dive (Глибоке занурення):

Historically, HTML parsing in PowerShell relied on Internet Explorer COM objects or regex hacks, but this was unreliable. AngleSharp, a modern .NET library, provides a robust and standards-compliant way to parse HTML. Other alternatives include HtmlAgilityPack and CsQuery. AngleSharp parses HTML into a Document Object Model (DOM) that you can query, making it similar to JavaScript’s document.
