'自动闭合UBB

    Dim arrTags, i, OpenPos, ClosePos, re, strMatchs, j, Match
    Set re = New RegExp            '申明re对象
    re.IgnoreCase = True        '设置是否区分字符大小写

    arrTags = Array("code", "quote", "list", "color", "align", "font", "size", "b", "i", "u", "html")    '建立数组，存储相关需要检测是否闭合的标签
    For i = 0 To UBound(arrTags)    '循环对数组里的每一个元素进行检测
        OpenPos = 0                '初始化当前标签开始标记的个数
        ClosePos = 0            '初始化当前标签结束标记的个数
        re.Pattern = "\[" + arrTags(i) + "(=[^\[\]]+|)\]"    '开始分别正则判断开始与结束标记的个数
