I get the following part work:</p> <pre><code>(?:' + tags + '):([\\s\\S]*?) </code></pre> <p>But the second part wont work with PHP, no matter what I try:</p> <pre><code>(?=\\s+(?:' + tags + '|END):) </code></pre> <p>Thank you for your help!</p> <p>Edit 1:</p> <p>My current PHP code looks like this:</p> <pre><code>$regexp = '(?:'.$tags.'):([\\s\\S]*?)(?=\\s+(?:'.$tags.'|END):)'; </code></pre> <p>Edit 2:</p> <p>I'm trying to find the following tags/parameters:</p> <pre><code>$tags = 'X-WR-CALNAME|X-WR-TIMEZONE|X-WR-CALDESC|BEGIN|CLASS|DTSTAMP|UID|CREATED|LAST-MODIFIED|SEQUENCE|STATUS|TRANSP|X-MICROSOFT-CDO-BUSYSTATUS|ORGANIZER|SUMMARY|DESCRIPTION|LOCATION|DTSTART|DTEND|END'; </code></pre> <p>...out of a text which looks like this:</p> <blockquote> <p>BEGIN:VEVENT DTSTART:20121117T143000Z DTEND:20121117T163000Z DTSTAMP:20121130T185808Z UID:n3f3qjgtads37phsq3oovmvouc@google.com CREATED:20121102T191518Z DESCRIPTION:1.

    1. COThis might sound silly, but you're making sure to concat the strings with `.` and not `+`, right? Can you show us your PHP code?

    3. COAnd what does the final regex look like? What are you trying to match (there might be another way, show us an example of the full text and what should be matched - maybe a link to a [RegEx101](http://www.regex101.com) permalink)?

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.
