    <p>This one will do a pretty good job. My definition of a sentence: A sentence begins with a non-whitespace and ends with a period, exclamation point or a question mark (or end of string). There may be a closing quote following the ending punctuation.</p> <p><code>[^.!?\s][^.!?]*(?:[.!?](?!['"]?\s|$)[^.!?]*)*[.!?]?['"]?(?=\s|$)</code> </p> <pre class="lang-java prettyprint-override"><code>import java.util.regex.*; public class TEST { public static void main(String[] args) { String subjectString = "This is a sentence. " + "So is \"this\"! And is \"this?\" " + "This is 'stackoverflow.com!' " + "Hello World"; String[] sentences = null; Pattern re = Pattern.compile( "# Match a sentence ending in punctuation or EOS.\n" + "[^.!?\\s] # First char is non-punct, non-ws\n" + "[^.!?]* # Greedily consume up to punctuation.\n" + "(?: # Group for unrolling the loop.\n" + " [.!?] # (special) inner punctuation ok if\n" + " (?!['\"]?\\s|$) # not followed by ws or EOS.\n" + " [^.!?]* # Greedily consume up to punctuation.\n" + ")* # Zero or more (special normal*)\n" + "[.!?]? # Optional ending punctuation.\n" + "['\"]? # Optional closing quote.\n" + "(?=\\s|$)", Pattern.MULTILINE | Pattern.COMMENTS); Matcher reMatcher = re.matcher(subjectString); while (reMatcher.find()) { System.out.println(reMatcher.group()); } } } </code></pre> <p>Here is the output:</p> <p><code>This is a sentence.</code><br> <code>So is "this"!</code><br> <code>And is "this?"</code><br> <code>This is 'stackoverflow.com!'</code><br> <code>Hello World</code> </p> <p>Matching all of these correctly (with the last sentence having no ending punctuation), turns out to be not so easy as it seems!</p>

    1. COShouldn't a sentence start with a capital letter, if it is starting with a letter? 1 of 100 examples starts with a uppercase letter, but with no letter at all.

    2. CO@user unknown: Maybe. But a sentence can be whatever you want to define it to be. My definition is stated above. For example, a sentence may begin with the name of program variable which starts with a lowercase letter.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
