077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	5 * Contributions by:
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	6 * Yousuke Kumakura (Attribute filters)
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	7 * Vadim Voituk (Negative indexes supports of "find" method)
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	8 * Antcs (Constructor with automatically load contents either text or file/url)
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	9 *
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	10 * all affected sections have comments starting with "PaperG"
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	11 *
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	12 * Paperg - Added case insensitive testing of the value of the selector.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	13 * Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	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,
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	15 * it will almost always be smaller by some amount.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	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.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	17 * but for most purposes, it's a really good estimation.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	18 * Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	19 * Allow the user to tell us how much they trust the html.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	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.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	21 * This allows for us to find tags based on the text they contain.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	22 * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	23 * Paperg: added parse_charset so that we know about the character set of the source document.
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	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
077b0a0a3e6d remaining originals according to dependency walk Robert Boland <robert@markup.co.uk> parents: diff changeset	25 * last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
