Overview ¶

Write a variadic function `ElementsByTagName` that, given an HTML node tree and zero or more names, returns all the elements that match one of those names. Here are two example calls:

`func ElementsByTagName(doc *html.Node, name ...string) []*html.Node`
`images := ElementsByTagName(doc, "img")``
`headings := ElementsByTagName(doc, "h1", "h2", "h3", "h4")``
