Creating java regex to get href link

Question

Sorry if this has been asked before, but I couldn\'t find any answers on the web. I\'m having a hard time figuring out the inverse to this regex:

\"\

Answer 1

If you always have one such link in a string, try this:

"(^[^\"]*\")|(\"[^\"]*)$"

Answer 2

You do not have to use replaceAll. Better use pattern groups like the following:

Pattern p = Pattern.compile("href=\"(.*?)\"");
Matcher m = p.matcher(html);
String url = null;
if (m.find()) {
    url = m.group(1); // this variable should contain the link URL
}

If you have several links into your HTML perform m.find() in loop.
