Removing each String between two strings and occuring after a specific string

Question

I have a String in Java :

style="hello World">One-time meetings< style=\"Hello Again"> stop "Hello" I want to remove all the strings that are between " ", occurring immediately after each occurrence of the String "Style".

So, after the removal, the above String will look like :

style="">One-time meetings< style=\""> stop "Hello"

~Thanks

Answer 1

If you want to remove all strings that are between the quotes in the style attribute then a simple replaceAll() should do the trick:

String input = "style=\"hello World\">One-time meetings< style=\"Hello Again\"> stop \"Hello\"";
input = input.replaceAll("style=\"(.*?)\"", "style=\"\"");

Update:

From inspecting your raw input, it appears that the quotes inside the <style> tags themselves are already escaped by a single backslash. If this be the case, then the following replacement should give you what you want:

String input = "style=\\\"hello World\\\">One-time meetings< style=\\\"Hello Again\\\"> stop \"Hello\"";
input = input.replaceAll("style=\\\\\"(.*?)\\\\\"", "style=\\\\\"\\\\\"?");

I think that parsing HTML with regex is a bad idea.
Please use a parser, like JSoup

Example code:

Document doc = Jsoup.parse(html);
doc.select(".style").attr("style", null);
String htmlWithoutStyle = doc.outerHtml();
