正则表达式来修改的htmlText AS3网址 [英] RegEx to modify urls in htmlText as3
问题描述
我有我设置成闪烁一个TextField一些HTML文本。我要强调的链接(或者在一个不同的颜色,可以仅通过使用下划线和确保链接目的地被设定为_blank
I have some html text that I set into a TextField in flash. I want to highlight links ( either in a different colour, either just by using underline and make sure the link target is set to "_blank".
我真的不擅长的正则表达式。我发现了一个方便的EX $ P $在 RegExr pssion:
I am really bad at RegEx. I found a handy expression on RegExr :
</?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>
但我不能使用它。
but I couldn't use it.
我将处理是这样的:
<a href="http://randomwebsite.web" />
我需要做一个与string.replace()
I will need to do a String.replace()
要得到这样的:
<u><a href="http://randomwebsite.web" target="_blank"/></u>
我不知道这会在一气呵成完成。重点是确保在链路目标设置为空白。
I'm not sure this can be done in one go. Priority is making sure the link has target set to blank.

下面是一个工作示例更复杂的输入字符串。
Here's a working example with a more complex input string.
var pattern:RegExp = /<a href="([\w:\/.-_]*)"[ ]* \/>/gi;
var str:String = 'hello world <a href="http://www.stackoverflow.com/" /> hello there';
var newstr = str.replace(pattern, '<li><a href="$1" target="blank" /></li>');
trace(newstr);
