Parse local HTML file

by

It appears that Invoke-WebRequest loads file protocol URIs just fine, but fails to parse them even in PowerShell 4.0 (where it is officially supported).

An alternative that does not require setting up a website would be to load and parse HTML directly into MSHTML.

$html = New-Object -ComObject "HTMLFile";
$source = Get-Content -Path "file.html" -Raw;
$html.IHTMLDocument2_write($source);

$html.links.length;

Note that when I tested this, a single

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

header prevented my HTML from parsing and I have no idea why — the document had similar XHTML-style headers and MSHTML had no issues with those.
