asp之自动闭合HTML/ubb标签函数 附简单注释

这最近在PJ的function库里看到的这个函数，感觉思路差了点，不过相对比较完美，只是闭合标签时的顺序问题，呵呵
修改一下数组arrTags里的各元素内容，可以达到闭合任何标签的功能。
在此，我给增加了一些注释，方便大家一起学习学习

代码如下：

Function closeUBB(strContent) 
'************************************* 
'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 
re.Global = True '设置全局可用性 
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 
Set strMatchs = re.Execute(strContent) 
For Each Match in strMatchs 
OpenPos = OpenPos + 1 
Next 
re.Pattern = "\[/" + arrTags(i) + "\]" 
Set strMatchs = re.Execute(strContent) 
For Each Match in strMatchs 
ClosePos = ClosePos + 1 
Next 
For j = 1 To OpenPos - ClosePos '当开始与结束标记数量不一致时，闭合当前标签 
strContent = strContent + "[/" + arrTags(i) + "]" 
Next 
Next 
closeUBB = strContent 
Set re = Nothing 
End Function

closehtml的注释同上

代码如下：

Function closehtml(strContent) 
'************************************* 
'自动闭合html 
'************************************* 
Dim arrTags, i, OpenPos, ClosePos, re, strMatchs, j, Match 
Set re = New RegExp 
re.IgnoreCase = True 
re.Global = True 
arrTags = Array("p", "DIV", "span", "table", "ul", "font", "b", "u", "i", "h1", "h2", "h3", "h4", "h5", "h6") 
For i = 0 To UBound(arrTags) 
OpenPos = 0 
ClosePos = 0 
re.Pattern = "\<" + arrTags(i) + "( [^\<\>]+|)\>" 
Set strMatchs = re.Execute(strContent) 
For Each Match in strMatchs 
OpenPos = OpenPos + 1 
Next 
re.Pattern = "\</" + arrTags(i) + "\>" 
Set strMatchs = re.Execute(strContent) 
For Each Match in strMatchs 
ClosePos = ClosePos + 1 
Next 
For j = 1 To OpenPos - ClosePos 
strContent = strContent + "</" + arrTags(i) + ">" 
Next 
Next 
closehtml = strContent 
Set re = Nothing 
End Function
