Regular expression to find anchor tag

[seena mathew]

I am trying to match an anchor tag using regular expression. I am new to regular expression and no matter what or how many times I have gone through regular expression the end result is that the pattern is not working.

Examples to match:

<a href="www.google.com" target="_blank">www.google.com</a>
<a href="www.google.com" >click me</a>
<a href="http://www.google.com" target="_blank">click me</a>
<a href="http://www.google.com" >click me</a>
<a href="www.google.com" >click me</a>
<a href="www.123-xyz.com" >click me</a>

  Pattern p = Pattern.compile("(<a.*href=')?(<A.*HREF=')?(<A.*HREF=\")?(<a.*href=\")?(http://)?[a-zA-Z_0-9\\-]+(\\.\\w[a-zA-Z_0-9\\-]+)+(/[#&\\n\\-=?\\+\\%/\\.\\w\">\\w\\s</a>])?");  
        

The pattern above is not picking up the full tag.
Any suggestion where the issue is ?

Got it working by modifying the pattern at http://www.coderanch.com/t/508917/java/java/Regex-find-URL-anchor-tag#2300082

  String pattern = "<a[^>]*?href\\s*=\\s*((\'|\")(.*?)(\'|\"))[^>]*?(?!/)>([\\w\\.\\s]+)</a>";
