Version Description
- Completely replaced the mechanism for parsing links to resolve the various errors that have been occurring with different external services' link attributes
- Added new option to apply to text widgets in addition to content and comment links. This will now handle 95% of the external link cases and allow for Apply Globally to be left off.
- Tested with WP 3.7

* Contributions by:
|
7 |
+
* Yousuke Kumakura (Attribute filters)
|
8 |
+
* Vadim Voituk (Negative indexes supports of "find" method)
|
9 |
+
* Antcs (Constructor with automatically load contents either text or file/url)
|
10 |
+
*
|
11 |
+
* all affected sections have comments starting with "PaperG"
|
12 |
+
*
|
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.
