Boards.xml quick tutorial

Open boards.xml, best is learn by example, so look at 4chan definition:

<site>
    <name>4chan.org</name>
    <!-- Below is first-page board link look, eg.:
        http://boards.4chan.org/g/1
        http://boards.4chan.org/tv/1
        etc.,
        (first page may sometimes not work, but if you try /g/3 (as 3rd page) so you know that is good)
            @BOARD@ and @PAGE are required to specify. -->
    <board_url>http://boards.4chan.org/@BOARD@/@PAGE@</board_url>
    <!-- If you're getting 404 ("no topics found") after first board page (boards.chan.org/board/1 URL) setting 
        this into `true` won't add "1" in that case -->
    <board_skip_1>true</board_skip_1>
    <!-- Below is link to thread, eg.:
        http://boards.4chan.org/g/thread/57704107
        looks similar? g - @BOARD@ and 57704107 is @TID@ - thread id
    ... -->
    <board_url_topic>http://boards.4chan.org/@BOARD@/thread/@TID@</board_url_topic>
    <!-- Below is url to target image (not thumbinal), eg.:
        http://i.4cdn.org/g/1480199776841.jpg
        so `g` is @BOARD@; `14801` is @FILE@ - so easy.
    -->
    <board_url_img>http://i.4cdn.org/@BOARD@/@FILE@</board_url_img>
    <!-- Now more complex... below is regexp which allows app to recognize what is what in board
        MATCHED must be in first () - that may be little difficult, sorry for that
    -->
    <patterns>
        <!-- Link to topic (often it's "Reply" pattern) - it resolves to @TID@ -->
        <reply><![CDATA[<a href=\"thread/([0-9]{2,15})/?[a-zA-Z0-9-]+?\".?(class=\"replylink\")?>Reply</a>]]></reply>
        <!-- Resolves to @FILE@ - only filename - 1480199776841.jpg from our above example
            IMPORTANT: first match must resolves to filename and second match to extension
            so: 1480199776841.jpg -> 1: (1480199776841) 2: (jpg)
            dunno why i did that in past ;)
        -->
        <image><![CDATA[<a class=\"fileThumb\" href=\"//i\.4cdn\.org/[a-zA-Z0-9]+/([0-9]+)\.([a-zA-Z0-9]{2,5})\" target=\"_blank\">]]></image>
    </patterns>
    <!-- Below is boards on that chan
        Values are injected into @BOARD@ variable.
        -->
    <boards_list>
        <b>a</b>
        <b>b</b>
        <b>c</b>
        <b>d</b>
        <!-- ... -->
        <b>vp</b>
        <b>wsg</b>
        <b>x</b>
    </boards_list>
    <!-- That's all - easy as fuck, is it? -->
