Question

I want to remove the tags similar to & apos; and & lt;

 pattern=Pattern.compile("'");
 match=pattern.matcher(line);
 match.replaceAll("");

But it doesn’t work . I also tried :

line=line.replace("&","");
line=line.replace("apos","");
line=line.replace(";","");

But this time , it replaces only the ; delimitor and not the & and apos ….

You should try following regex to remove following patterns: <, >, ' &:

Pattern pattern = Pattern.compile("&(lt;|apos;|gt;|)");

TESTING:

Matcher m = pattern.matcher("abc &def ' xyz< > mno");
System.out.printf("line=[%s]\n", m.replaceAll(""));

OUTPUT:

line=[abc def  xyz  mno]
