如何在Aptana Studio 3中使用正则表达式更改匹配的组文本的大小写？

Question

I have the following HTML code:

 <input type="radio" name="appearance" /> <label>Appropriate</label> 

I'm using the following regular expression to extract the text within the label tags (not a regex expert, so this works for me, please advice of better way):

(<input \btype="radio"\s\b\bname\b="[\w://.]*") \/>(\s+)(<label>(.*?)<\/label>)

I'm using the following to replace the code:

$1 value=\"$4\"\>$2$3

This changes the original HTML to:

 <input type="radio" name="appearance" value="Appropriate"> <label>Appropriate</label> 

However, I want the value, "Appropriate" in this case, to be lowercase. I have tried adding \\L with no luck.

Any help is appreciated.

Thanks.

If you're doing this in JavaScript, you can just use tolowerCase() in
the callback function.

 var input = '\\ <input type="radio" name="appearance" />\\n\\ <label>Appropriate</label>'; var output = input.replace( /(<input[ ]\\btype="radio"\\s\\b\\bname\\b="[\\w:\\/\\/.]*")[ ]\\/>(\\s+)<label>(.*?)<\\/label>/, function( m,p1,p2,p3, p4 ) { return p1 + " value=\\"" + p4 + "\\"\\>" + p2+ "<label>" + p3.toLowerCase() + "</label>"; } ); console.log( output );
