External Links - Version 4.2

Version Description

  • WP 3.6 compat
  • PHP 5.4 compat
  • Fixed issue with parsing of links with non-standard (class, href, rel, target) attributes included in the tag. This caused Twitter Widgets to break.
  • Fixed issue where the external link icon was not added if the url specified by href had a preceding space href=" http://www.example.com"
  • Fixed issue with links containing onClick (or other javascript event) attributes with embedded javascript code. WordPress' Threaded Comments does this
  • Fixed issue with 2 spaces being injected between

- * 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.
