- //
- // primary → (ruleset | rule)+
- // ruleset → selector+ block
- // block → '{' primary '}'

- *
- * all affected sections have comments starting with "PaperG"
- *
- * Paperg - Added case insensitive testing of the value of the selector.
- * Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
- * 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,
- * it will almost always be smaller by some amount.
- * 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.
- * but for most purposes, it's a really good estimation.
- * Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
- * Allow the user to tell us how much they trust the html.
- * 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.
- * This allows for us to find tags based on the text they contain.
- * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
- * Paperg: added parse_charset so that we know about the character set of the source document.
- * 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
- * last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
- *
- * Found infinite loop in the case of broken html in restore_noise. Rewrote to protect from that.
- * PaperG (John Schlick) Added get_display_size for "IMG" tags.
