replaceUrlsByTags

java.lang.String replaceUrlsByTags(java.lang.String html)

Replaces URLs to to internal tags. Normally a call to sanitize(String) is sufficient, but there might be cases where an HTML sanitization is not needed, just the replacing of URL tags by full URLs. The following tags are handled:

• {{config:<name>}}: Configuration image URL. See ConfigurationImageType.
• {{user:<key>:<size>}}: User profile image URL. See UserImage.
• {{usercustom:<key>:size>}}: User custom image URL. See UserCustomImage.
• {{ad:<key>:size>}}: Advertisement image URL. See AdImage.
• {{systemcustom:<key>:size>}}: System custom image URL. See SystemCustomImage.

java.lang.String replaceUrlsByTags(java.lang.String html,
                                   User user)

Same as replaceUrlsByTags(String) but using the root url and network of the specified user,

sanitize

java.lang.String sanitize(java.lang.String html)

Sanitizes the given HTML, removing blacklisted tags, correctly closing unclosed tags and removing leading / trailing whitespaces. Administrators are allowed to use iframes and forms, but not regular users. Scripts and style tags are forbidden. Null inputs, as well as empty strings, results in null.

unescapeTags

java.lang.String unescapeTags(java.lang.String text)

Replaces all '< ' by '<', reverting the result of escapeTags(String)
