How do I use regex in Java to pull this from html?

I'm trying to pull data from the ESPN box scores, and one of the html files has:

<td style="text-align:left" nowrap><a href="http://espn.go.com/nba/player/_/id/2754/channing-frye">Channing Frye</a>, PF</td>

and I'm only interested in grabbing the name (Channing Frye) and the position (PF)

Right now, I've been using Pattern.quote(start) + "(.*?)" + Pattern.quote(end) to grab text in between start and end, but I'm not sure how I'm supposed to grab text that starts with pattern .../http://espn.go.com/nba/player/_/id/ and then can contain (any integer)/anyfirst-anylast"> then grab the name I need (Channing Frye), then </a>, and then grab the position I need (PF) and ends with pattern </td>

Thanks!

You can use :

String lString = "<td style=\"text-align:left\" nowrap><a href=\"http://espn.go.com/nba/player/_/id/2754/channing-frye\">Channing Frye</a>, PF</td>";
Pattern lPattern = Pattern.compile("<td.+><a.+id/\\d+/.+\\-.+>(.+)</a>, (.+)</td>");
Matcher lMatcher = lPattern.matcher(lString);
while(lMatcher.find()) {
    System.out.println(lMatcher.group(1));
    System.out.println(lMatcher.group(2));
}

This will give you :

Channing Frye
PF

Here is one regex:

  • . is used for any item, .+ is used for any 1+ items
  • .* means o or more items

  • \s is used for space

    String str = "<td style=\"text-align:left\" nowrap><a href=\"http://espn.go.com/nba/player/_/id/2754/channing-frye\">Channing Frye</a>, PF</td>";
Pattern pattern = Pattern.compile("<td.+>.*<a.+>(.+)</a>[\\s,]+(.+)</td>");
Matcher matcher = pattern.matcher(str);

while(matcher.find()){
    System.out.println(matcher.group(1));
    System.out.println(matcher.group(2));
}

Use this regex:

[A-Z\sa-z0-9]+(?=</a>)|\w+(?=</td>)

You could use this pattern:

\\/nba\\/player\\/_\\/.*\\\">(.*)<.+>,\\s(.*)<

This will match any link in the html that contains `/nba/player/

String re = "\\/nba\\/player\\/_\\/.*\\">(.*)<.+>,\\s(.*)<";
String str = "<td style=\"text-align:left\" nowrap><a href=\"http://espn.go.com/nba/player/_/id/2754/channing-frye\">Channing Frye</a>, PF</td>";

Pattern p = Pattern.compile(re, Pattern.MULTILINE | Pattern.CASE_INSENSITIVE);
Matcher m = p.matcher(str);

Here is the pattern:

http://espn.go.com/nba/player/_/id/(\d+)/([\w-]+)">(.*?)</a>,\s*(\w+)</td>
