Functions ¶

func CSS ¶

func CSS(root *parser.Adaptable, sel string) ([]*parser.Adaptable, error)

CSS selects elements matching a CSS selector from the given root.

func CSSAttr ¶

func CSSAttr(root *parser.Adaptable, sel, attr string) ([]string, error)

CSSAttr extracts attribute values from elements matching a CSS selector with ::attr(name) pseudo-element.

func CSSFirst ¶

func CSSFirst(root *parser.Adaptable, sel string) (*parser.Adaptable, error)

CSSFirst selects the first element matching a CSS selector.

func CSSText ¶

func CSSText(root *parser.Adaptable, sel string) ([]string, error)

CSSText extracts text from elements matching a CSS selector with ::text pseudo-element.

func XPath ¶

func XPath(root *parser.Adaptable, expr string) ([]*parser.Adaptable, error)

XPath selects elements matching an XPath expression from the given root. This is a simplified XPath implementation supporting common patterns.

func XPathFirst ¶

func XPathFirst(root *parser.Adaptable, expr string) (*parser.Adaptable, error)

XPathFirst selects the first element matching an XPath expression.

Types ¶

type PseudoResult ¶

type PseudoResult struct {
	Nodes []*parser.Adaptable
	Texts []string // populated for ::text or ::attr()
}
