Regular Expression Help??

qajussi · Apr 18, 2005

I am trying find and delete a tag.
Say I want <html>, < HTML >, </html>, </ HTML> to be deleted..

There could be one or more spaces between < and h.
They can be upper or lowercases..
esponseString = some html page.
Pattern pattern = Pattern.compile("</?[hH][tT][mM][lL]>", Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(responseString);
responseString = matcher.replaceAll("");

Can you help?? please

I wouldn't bother with all that ...

Code:

String line = "<html> hello </html>";
line = line.replaceAll("<html>", "").replaceAll("</html>", "").replaceAll("<HTML>", "").replaceAll("</HTML>", "").trim();
System.out.println(line);

What if there are some space between < html>
or </ html> like that??

That woyld not resolve the spaces thingie but anyway I think html tags cannot have spaces inside.

Maybe this is useful:

try out this.

public class Test {
public static void main(String[] args) {
CharSequence inputStr = "a< html></ html>cb<html>d< HTML>e</ HTml>";
String patternStr = "</?\\s*html>";

Pattern pattern = Pattern.compile(patternStr,Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(inputStr);

String result = matcher.replaceAll("");
System.out.println("result : " + result);
}
}
