# perldoc > HTML::AsSubs --- type: CommandReference command: HTML::AsSubs mode: perldoc section: "" source: perldoc --- ## Quick Reference - `use HTML::AsSubs;` — import all HTML tag functions - `body(h1("Title"), p("Text"))` — construct a `` with heading and paragraph - `a({href=>'url'}, "link")` — anchor with attributes - `img({src=>'img.gif', alt=>'image'})` — image element with attributes - `print $h->as_HTML;` — output the HTML tree as a string - `html(head(title("Page")))` — nested structure ## Name `HTML::AsSubs` — functions that construct a HTML syntax tree ## Synopsis perl use HTML::AsSubs; $h = body( h1("This is the heading"), p("This is the first paragraph which contains a ", a({href=>'link.html'}, "link"), " and an ", img({src=>'img.gif', alt=>'image'}), "." ), ); print $h->as_HTML; ## Options The module exports functions named after HTML tags (lowercase).

Commonly used functions: - `html` — root element - `head`, `body`, `title` — document structure - `h1`, `h2`, `h3`, `h4`, `h5`, `h6` — headings - `p`, `div`, `span`, `br`, `hr` — block/inline elements - `a`, `img` — links and images - `ul`, `ol`, `li`, `dl`, `dt`, `dd` — lists - `table`, `tr`, `td`, `th`, `caption` — tables - `form`, `input`, `select`, `option`, `textarea` — forms - `script`, `style`, `link`, `meta` — head elements - And many others: `base`, `blockquote`, `pre`, `code`, `em`, `strong`, `b`, `i`, `u`, `tt`, `big`, `small`, `sub`, `sup`, `dfn`, `cite`, `samp`, `kbd`, `var`, `address`, `font`, `center`, `strike`, `object`, `applet`, `param`, `map`, `area`, `frame`, `frameset`, `noframe`, `isindex`, `nextid`, `menu`, `dir` Note: `link()` overrides Perl’s builtin `link`; `tr()` must be called as `&tr(...)` due to the builtin `tr///` operator. ## Examples perl # Simple document print html( head(title("My Page")), body( h1("Welcome"), p("Some text.") ) )->as_HTML; # Attributes via hashref print div({id => "main", class => "container"}, "Content")->as_HTML; ## See Also - [HTML::Element](perldoc/HTML::Element) - [XML::Generator](perldoc/XML::Generator)
