    <p>I'd keep this as simple as possible:</p> <pre><code>entries = [] for line in inputsource: entries.append(map(str.strip, line.strip().strip('{}').split(', '))) </code></pre> <p>So, for each line, strip whitespace then curly braces, then split on the comma-plus-space separating the commands and store the whitespace-stripped results.</p> <p>This relies on the fact that the commands are separated by a comma plus a space, while the arguments in your sample only use commas without spaces. If you have anything that violates that difference, then you do need to resort to a regular expression. I'd limit it to the split only though:</p> <pre><code>import re commandsep = re.compile(r'(?&lt;=\)),\s*') for line in inputsource: entries.append(map(str.strip, commandsep.split(line.strip().strip('{}')))) </code></pre> <p>The <code>commandsep</code> expression splits on any comma-plus-optional-whitespace, provided it was preceded by a <code>)</code> closing parenthesis (using a look-behind assertion).</p> <p>For your input that results in:</p> <pre><code>&gt;&gt;&gt; entries [['topic.equals(org.fedoraproject.prod.bodhi.buildroot_override.tag)', 'foo.notequals(bar)'], ['topic.in(1,2,3)', 'foo.equals(baz)']] </code></pre> <p>If these entries are embedded in a larger body of text, then a regular expression might help, but only to find the curly-brace-delimited values:</p> <pre><code>import re expression = re.compile(r'{[^{}]+}') inputsource = expression.findall(largerbodyoftext) </code></pre> <p>where <code>expression</code> will find any text delimited by curly braces (no nesting).</p>

    1. COThis doesn't quite work, you'll notice in your section: ['topic.in(1', '2', '3)', 'foo.equals(baz)'] the first string is 'topic.in(1' which isn't valid, it should be 'topic.in' and then '1', '2', '3' OR one solid string that I can use a regex on 'topic.in(1,2,3)'

    2. CO@sontek: ick, right. Parsing fun. For your *specific example* adding a space to the split is all that is needed though.

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.
