    <p>Have worked in dozens of languages but new to Python.</p> <p>My first (maybe second) question here, so be gentle...</p> <p>Trying to efficiently convert HTML-like markdown text to wiki format (specifically, Linux Tomboy/GNote notes to Zim) and have gotten stuck on converting lists. </p> <p>For a 2-level unordered list like this...</p> <ul> <li>First level <ul> <li>Second level</li> </ul></li> </ul> <p>Tomboy/GNote uses something like...</p> <p><code>&lt;list&gt;&lt;list-item&gt;First level&lt;list&gt;&lt;list-item&gt;Second level&lt;/list-item&gt;&lt;/list&gt;&lt;/list-item&gt;&lt;/list&gt;</code></p> <p>However, the Zim personal wiki wants that to be...</p> <pre><code>* First level * Second level </code></pre> <p>... with leading tabs.</p> <p>I've explored the regex module functions re.sub(), re.match(), re.search(), etc. and found the cool Python ability to code repeating text as...</p> <pre><code> count * "text" </code></pre> <p>Thus, it looks like there should be a way to do something like...</p> <pre><code> newnote = re.sub("&lt;list&gt;", LEVEL * "\t", oldnote) </code></pre> <p>Where LEVEL is the ordinal (occurrance) of <code>&lt;list&gt;</code> in the note. It would thus be <code>0</code> for the first <code>&lt;list&gt;</code> incountered, <code>1</code> for the second, etc.</p> <p>LEVEL would then be decremented each time <code>&lt;/list&gt;</code> was encountered.</p> <p><code>&lt;list-item&gt;</code> tags are converted to the asterisk for the bullet (preceded by newline as appropriate) and <code>&lt;/list-item&gt;</code> tags dropped.</p> <p>Finally... the question...</p> <ul> <li>How do I get the value of LEVEL and use it as a tabs multiplier?</li> </ul>

    1. COOff the top of my head, use an html/xml parser such as BeautifulSoup or xml.dom.minidom, use a recursive function or use a stack/queue to open/close tags and count tablevels. Basically, you want to convert the markup text into usable data. then convert this code-friendly data to your other style of markup.

    2. COdon't use `re`. it's not very effective at dealing with nested tags.

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.
