    <p>The best solution (in my opinion) would be to use multiple regular expressions, each one for a different format. Regular expressions tend to grow quite large quite fast so maintaining them can be a daunting experience.</p> <p>What I would do would be to use something like these:</p> <ul> <li><code>(2)[ -]+(\d{2})[ -]+(\d{2})[ -]+(\d{2})</code> to match the first pattern (new land line phones): <code>2-XX-XX-XX</code>.</li> <li><code>(\d{2})[ -]+(\d{2})[ -]+(\d{2})</code> to match the second pattern (old land line phones): 6 digits.</li> <li><code>(8\d{2})[ -]+(\d{2})[ -]+(\d{2})[ -]+(\d{2})</code> to match the third pattern (old mobile phones): <code>8XX-YY-YY-YY</code>.</li> <li><code>(5\d{2})[ -]+(\d{2})[ -]+(\d{2})[ -]+(\d{2})</code> to match the fourth pattern (new mobile phones): <code>5XX-YY-YY-YY</code>.</li> </ul> <p>You will have to use the above expressions to see which expression will match the format of the number you have entered. Note that these expressions assume that the numbers making up the phone number are separated by a white space (<code></code>) or a dash (<code>-</code>).</p> <p>If the pattern will match, the regular expression engine will also throw in the numbers making up the phone number into groups, denoted by the <code>(</code> and <code>)</code> brackets. You can then reconstruct the phone number in any way you wish by accessing these groups and create new strings representing the newly formatted phone.</p> <p>To see how you can use regular expression groups in Javascipt, please take a look <a href="https://stackoverflow.com/questions/432493/how-do-you-access-the-matched-groups-in-a-javascript-regex">here</a>.</p>

    1. COThat did help me a lot to get familiar with regular expression. I think I now know how to handle this problem. Thanks! ;)

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.
