## **NOTE**: The behaviour might change in future versions as it is not
## clear what "*wild* HTML the real world uses" really implies.
##
## It can be used to parse a wild HTML document and output it as valid XHTML
## document (well, if you are lucky):
##
## .. code-block:: Nim
##
##   echo loadHtml("mydirty.html")
##
## Every tag in the resulting tree is in lower case.
##
## **Note:** The resulting ``XmlNode`` already uses the ``clientData`` field,
## so it cannot be used by clients of this library.
##
## Example: Transforming hyperlinks
## ================================
##
## This code demonstrates how you can iterate over all the tags in an HTML file
## and write back the modified version. In this case we look for hyperlinks
## ending with the extension ``.rst`` and convert them to ``.html``.
##
## .. code-block:: Nim
##     :test:
##
##   import htmlparser
##   import xmltree  # To use '$' for XmlNode
##   import strtabs  # To access XmlAttributes
##   import os       # To use splitFile
##   import strutils # To use cmpIgnoreCase
##
##   proc transformHyperlinks() =
##     let html = loadHtml("input.html")
##
##     for a in html.findAll("a"):
##       if a.attrs.hasKey "href":
##         let (dir, filename, ext) = splitFile(a.attrs["href"])
##         if cmpIgnoreCase(ext, ".rst") == 0:
##           a.attrs["href"] = dir / filename & ".html"
##
##     writeFile("output.html", $html)
