/* This file contains the files necessary to display news as an XML feed.
void ShowXmlFeed()
- is called to output xml information.
- can be passed four subactions which decide what is output: 'recent'
for recent posts, 'news' for news topics, 'members' for recently
registered members, and 'profile' for a member's profile.
- To display a member's profile, a user id has to be given. (;u=1)
- uses the Stats language file.
- outputs an rss feed instead of a proprietary one if the 'type' get
parameter is 'rss' or 'rss2'.
- does not use any templates, sub templates, or template layers.
- is accessed via ?action=.xml.
void dumpTags(array data, int indentation, string tag = use_array)
- formats data retrieved in other functions into xml format.
- the data parameter is the array to output as xml data.
- indentation is the amount of indentation to use.
- if a tag is specified, it will be used instead of the keys of data.
- this function is recursively called to handle sub arrays of data.
array getXmlMembers(bool rss)
- is called to retrieve list of members from database.
- if rss is true, the array will be done in the RSS standard.
- returns array of data.
array getXmlNews(bool rss)
- is called to retrieve news topics from database.
- takes one argument, rss, to decide if data should be RSS standard.
- returns array of topics.
array getXmlRecent(bool rss)
- is called to retrieve list of recent topics.
- takes one argument, rss, to decide if data should be RSS standard.
- returns an array of recent posts.
array getXmlProfile(bool rss)
- is called to retrieve profile information for member into array.
- takes one argument, rss, to decide if data should be RSS standard.
- returns an array of data.
