13 |
-
* Paperg - Added case insensitive testing of the value of the selector.
|
14 |
-
* Paperg - Added tag_start for the starting index of tags - NOTE: This works but not accurately.
|
15 |
-
* 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,
|
16 |
-
* it will almost always be smaller by some amount.
|
17 |
-
* 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 |
-
* but for most purposes, it's a really good estimation.
|
19 |
-
* Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags closed is great for malformed html, but it CAN lead to parsing errors.
|
20 |
-
* Allow the user to tell us how much they trust the html.
|
21 |
-
* 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 |
-
* This allows for us to find tags based on the text they contain.
|
23 |
-
* Create find_ancestor_tag to see if a tag is - at any level - inside of another specific tag.
|
24 |
-
* Paperg: added parse_charset so that we know about the character set of the source document.
|
25 |
-
* 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
|
26 |
-
* last transfer or curl_exec, and we will parse that and use it in preference to any other method of charset detection.
|
27 |
-
*
|
28 |
-
* Found infinite loop in the case of broken html in restore_noise. Rewrote to protect from that.
|
29 |
-
* PaperG (John Schlick) Added get_display_size for "IMG" tags.
