   3 |  * Website: http://sourceforge.net/projects/simplehtmldom/
   4 |  * Acknowledge: Jose Solorzano (https://sourceforge.net/projects/php-html/)
   5 |  * Contributions by:
   6 |  *     Yousuke Kumakura (Attribute filters)
   7 |  *     Vadim Voituk (Negative indexes supports of "find" method)
   8 |  *     Antcs (Constructor with automatically load contents either text or file/url)
   9 |  *
  10 |  * all affected sections have comments starting with "PaperG"
  11 |  *
  12 |  * Paperg - Added case insensitive testing of the value of the selector.
  13 |  * Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
  14 |  *  This tag_start gets counted AFTER \r\n have been crushed out, and after the remove_noice calls so it will not reflect the REAL position of the tag in the source,
  15 |  *  it will almost always be smaller by some amount.
  16 |  *  We use this to determine how far into the file the tag in question is.  This "percentage will never be accurate as the $dom->size is the "real" number of bytes the dom was created from.
  17 |  *  but for most purposes, it's a really good estimation.
  18 |  * Paperg - Added the forceTagsClosed to the dom constructor.  Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
  19 |  * Allow the user to tell us how much they trust the html.
  20 |  * Paperg add the text and plaintext to the selectors for the find syntax.  plaintext implies text in the innertext of a node.  text implies that the tag is a text node.
  21 |  * This allows for us to find tags based on the text they contain.
  22 |  * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
  23 |  * Paperg: added parse_charset so that we know about the character set of the source document.
  24 |  *  NOTE:  If the user's system has a routine called get_last_retrieve_url_contents_content_type availalbe, we will assume it's returning the content-type header from the
  25 |  *  last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
  26 |  *
  27 |  * Found infinite loop in the case of broken html in restore_noise.  Rewrote to protect from that.
  28 |  * PaperG (John Schlick) Added get_display_size for "IMG" tags.
