17 /* This file contains the files necessary to display news as an XML feed.
18
19 void ShowXmlFeed()
20 - is called to output xml information.
21 - can be passed four subactions which decide what is output: 'recent'
22 for recent posts, 'news' for news topics, 'members' for recently
23 registered members, and 'profile' for a member's profile.
24 - To display a member's profile, a user id has to be given. (;u=1)
25 - uses the Stats language file.
26 - outputs an rss feed instead of a proprietary one if the 'type' get
27 parameter is 'rss' or 'rss2'.
28 - does not use any templates, sub templates, or template layers.
29 - is accessed via ?action=.xml.
30
31 void dumpTags(array data, int indentation, string tag = use_array,
32 string format)
33 - formats data retrieved in other functions into xml format.
34 - additionally formats data based on the specific format passed.
35 - the data parameter is the array to output as xml data.
36 - indentation is the amount of indentation to use.
37 - if a tag is specified, it will be used instead of the keys of data.
38 - this function is recursively called to handle sub arrays of data.
39
40 array getXmlMembers(string format)
41 - is called to retrieve list of members from database.
42 - the array will be generated to match the format.
43 - returns array of data.
44
45 array getXmlNews(string format)
46 - is called to retrieve news topics from database.
47 - the array will be generated to match the format.
48 - returns array of topics.
49
50 array getXmlRecent(string format)
51 - is called to retrieve list of recent topics.
52 - the array will be generated to match the format.
53 - returns an array of recent posts.
54
55 array getXmlProfile(string format)
56 - is called to retrieve profile information for member into array.
57 - the array will be generated to match the format.
58 - returns an array of data.
