Functions

func ExtractBaseHref

func ExtractBaseHref(doc *goquery.Document) string

ExtractBaseHref finds the <base href="..."> value from the document.

func ResolveRelativeURLs

func ResolveRelativeURLs(element *goquery.Selection, pageURL string, docBaseHref string)

ResolveRelativeURLs resolves all relative URLs in the element against baseURL. It handles href, src, srcset, poster, and data-src attributes. docBaseHref overrides the base URL if a <base href> tag was present.

func SanitizeUnsafe

func SanitizeUnsafe(element *goquery.Selection)

SanitizeUnsafe strips dangerous elements, event handlers, and unsafe URLs from the extracted content to prevent XSS when the HTML is rendered.
