OK I am trying to strip off all html tags but this doesn't work...why not?
lines[i].replaceAll("\\<.*\\>", "");

Asusming I have a string called htmlPage, how do I convert the <p> and <br> to new lines? htmlPage is a string containing the whole html page and is multiline.

Also you can replace all tags by using..

htmlString = htmlString.replaceAll("<.*>", "");

dont forget, that replaceAll returns the resultant string..

you're using a greedy quantifier, try:

lines[i].replaceAll("\\<.*?\\>", "");

> how do I convert the <p> and <br> to new lines?

line.replaceAll("\\<p\\>", "\n").replaceAll("\\<br\\>", "\n");

Sorry...

typo mistake.

htmlString = htmlString.replaceAll("<.*>", "");

should be htmlString = htmlString.replaceAll("<[a-z]*>", "");

what you look for is;
lines[i].replaceAll("</.*?>", "").replaceAll("<.*?>", "\n");

I accepted cmalakar as a solution as I was completely unaware that replaceAll returned the resultant string.
