If not, see . # This file implements a parser for html snippets, meant to be used by a # WYSIWYG editor. Hence it does not attempt to parse doctypes, , # or tags, nor does it produce the top level "document" node in the dom # tree, nor nodes for html, head or body. Comments containing "fixfull" # indicate places where additional code is needed for full HTML document # parsing. # # Instead, the data structure produced by this parser is an array of Nodes. # stacks/lists # # the spec uses a many different words do indicate which ends of lists/stacks # they are talking about (and relative movement within the lists/stacks). This # section splains. I'm implementing "lists" (afe and open_els) the same way # (both as stacks) # # stacks grow downward (current element is index=0) # # example: open_els = [a, b, c, d, e, f, g] # # "grows downwards" means it's visualized like this: (index: el, names) # # 6: g "start of the list", "topmost", "first" # 5: f # 4: e "previous" (to d), "above", "before" # 3: d (previous/next are relative to this element) # 2: c "next", "after", "lower", "below" # 1: b # 0: a "end of the list", "current node", "bottommost", "last" # browser # note: to get this to run outside a browser, you'll have to write a native # implementation of decode_named_char_ref() unless module?.exports? window.wheic = {} module = exports: window.wheic # Each node is an obect of the Node class.
