<?php /** * Website: http://sourceforge.net/projects/simplehtmldom/ * Acknowledge: Jose Solorzano (https://sourceforge.net/projects/php-html/) * Contributions by: * Yousuke Kumakura (Attribute filters) * Vadim Voituk (Negative indexes supports of "find" method) * Antcs (Constructor with automatically load contents either text or file/url) * * 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. * * Licensed under The MIT License * Redistributions of files must retain the above copyright notice. * * @author S.C.
