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.

Robert Boland <robert@markup.co.uk>
parents:

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.

18 * Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.

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.

22 * Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
