+--------
+Version 1.3.7.
+http://pixel-apes.com/safehtml/
+--------
+
+This parser strips down all potentially dangerous content within HTML:
+ * opening tag without its closing tag
+ * closing tag without its opening tag
+ * any of these tags: "base", "basefont", "head", "html", "body", "applet", "object",
+ "iframe", "frame", "frameset", "script", "layer", "ilayer", "embed", "bgsound",
+ "link", "meta", "style", "title", "blink", "xml" etc.
+ * any of these attributes: on*, data*, dynsrc
+ * javascript:/vbscript:/about: etc. protocols
+ * expression/behavior etc. in styles
+ * any other active content
+It also tries to convert code to XHTML valid, but htmltidy is far better solution for this task.
+
+If you found any bugs in this parser, please inform me -- ICQ:551593 or mailto:thingol@mail.ru
+
+Please, subscribe to http://pixel-apes.com/safehtml/feed/rss feed in order to receive notices
+when SAFEHTML will be updated.

+Version history:
+--------
+1.3.7.
+ * Added 'dl' to the list of 'lists' tags.
+ * Added 'callto' to the white list of protocols.
+ * Added white list of "namespaced" attributes.
+1.3.6.
+ * More accurate UTF-7 decoding.
+1.3.5.
+ * Two serious security flaws fixed: UTF-7 XSS and CSS comments handling.
+1.3.2.
+ * Security flaw (improper quotes handling in attributes' values) fixed. Big thanks to Nick Cleaton.
+1.3.1.
+ * Dumb bug fixed (some closing tags were ignored).
+1.3.0.
+ * Two holes (with decimal HTML entities and with \x00 symbol) fixed.
+ * Class rewritten under PEAR coding standarts.
+ * Class now uses unmodified HTMLSax3 from PEAR.
+ * To the list of table tags added: "caption", "col", "colgroup".
+1.2.1.
+ * It was possible to create XSS with hexadecimal HTML entities. Fixed. Big thanks to Christian Stocker.
+1.2.0.
+ * "id" and "name" attributes added to dangerous attributes list, because malefactor can broke legal javascript by spoofing ID or NAME of some element.
+ * New method parse() allows to do all parsing process in two lines of code. Examples also updated.
+ * New array, closeParagraph, contains list of block-level elements. When we open such elemet, we should close paragraph before. . It allows SafeHTML to produce more XHTML compliant code.
+ * Added "webcal" to white list of protocols for those who uses calendar programs (Mozilla/iCal/etc).
+ * Now SafeHTML strips down table elements when we are not inside table.
+ * Now SafeHTML correctly closes unclosed "li" tags: before opening "li" of the same nesting level.
+1.1.0.
+ * New "dangerous" protocols: hcp, ms-help, help, disk, vnd.ms.radio, opera, res, resource, chrome, mocha, livescript.
+ * <XML> tag was moved from "tags for deletion" to "tags for deletion with content".
+ * New "dangerous" CSS instruction "include-source" (NN4 specific).
+ * New array, Attributes, contains list of attributes for removal. If you need to remove "id" or "name" attribute,
+ just add it to this array.
+ * Now it is possible to choose between white-list and black-list filtering of protocols. Defaults are "white-list".
+ This list is: "http", "https", "ftp", "telnet", "news", "nntp", "gopher", "mailto", "file".
+ * For speed purposes, we now filter protocols only from these attributes: src, href, action, lowsrc, dynsrc,
+ background, codebase.
+ * Opera6 XSS bug ([\xC0][\xBC]script>alert(1)[\xC0][\xBC]/script> [UTF-8] workarounded.
+1.0.4.
+ New "dangerous" tag: plaintext.
+1.0.3.
+ Added array of elements that can have no closing tag.
+1.0.2.
+ Bug fix: <img src="javascript:alert(1);"> attack.
+ Thanks to shmel.
+1.0.1.
+ Bug fix: safehtml hangs on <style></style></style> code.
+ Thanks to lj user=electrocat.
+1.0.0.
