'用法 RHtml=SimpleHTML(html,"p,img,a,span")
Function SimpleHTML(content,tags)
If tags="" Then tags="p,br"
SimpleHTML = RegReplace("<(\/?)("& Replace(tags,",","|") &")([^>]*)>",content&"","[$1$2$3]")
SimpleHTML = RegReplace("<[^>]*>",SimpleHTML,"")
SimpleHTML = RegReplace("\[(\/?)("& Replace(tags,",","|") &")([^\]]*)\]",SimpleHTML,"<$1$2$3>")
End Function
'生成一个正则表达式对象
Function REObject( reg, m)
Dim re:Set re=new RegExp
re.Pattern = reg
If InStr(1, m, "g", 1)>0 Then re.Global = True
If InStr(1, m, "i", 1)>0 Then re.IgnoreCase = True
If InStr(1, m, "m", 1)>0 Then re.MultiLine = True
Set REObject=re
End Function
Function RegReplace( reg, str, rstr)
RegReplace=RegExpReplace(reg,"ig",str,rstr)
End Function
'正则替换字符串
Function RegExpReplace( reg, m, str, rstr)
RegExpReplace=REObject(reg, m).Replace(str,rstr)
End Function
后面几个是用到的函数
会将html代码中非指定的标签全部去除，如果要去除标签内的属性，需要修改下simplehtml这个函数，把$3去掉
Function SimpleHTML(content,tags)
If tags="" Then tags="p,br"
SimpleHTML = RegReplace("<(\/?)("& Replace(tags,",","|") &")([^>]*)>",content&"","[$1$2$3]")
SimpleHTML = RegReplace("<[^>]*>",SimpleHTML,"")
SimpleHTML = RegReplace("\[(\/?)("& Replace(tags,",","|") &")([^\]]*)\]",SimpleHTML,"<$1$2>")
End Function
