regex - 用标签替换自定义标签

Answer 1

根据 HamZa DzCyber​​DeV 的评论，我在RegexHero中使用了 RegEx 模式，发现 RegExHero 甚至生成了 ASP.NET。因此，下面的简单代码完全达到了我需要的结果：

Dim s As String = txt_input.Text.Trim
Dim strRegex As String = "\[url\s?=\s?""?(.*?)""?\](.*?)\[\/url\]"
Dim myRegex As New Regex(strRegex)
Dim strReplace As String = "<a href=""$1"">$2</a>"
ltl_output.Text = myRegex.Replace(s, strReplace)

据我了解，您需要一个用于 ASP.NET 的 BBCode 转换器，您可以在此处找到。

给定链接的示例：

string BBCodeSyntax = "[url={webaddress}]{display}[/url]"; 
string HtmlSyntax = "<a href=\"{webaddress}\">{display}</a>"; 
string Fields = "{webaddress};{display}"; 

string input = "For those who code - [url=http://www.codeproject.com]The CodeProject[/url]. This website contains lots of articles about programming. For open source project hosting from Microsoft, you may have a look at [url=http://www.codeplex.com]Codeplex.com[/url]."; 

string output = BBCode.ConvertToHtml(input, BBCodeSyntax, HtmlSyntax, Fields); 
return output;
