    <p>I'm attempting to learn XML in order to parse GChats downloaded from GMail via IMAP. To do so I am using lxml. Each line of the chat messages is formatted like so:</p> <pre><code>&lt;cli:message to="email@gmail.com" iconset="square" from="email@gmail.com" int:cid="insertid" int:sequence-no="1" int:time-stamp="1236608405935" xmlns:int="google:internal" xmlns:cli="jabber:client"&gt; &lt;cli:body&gt;Nikko&lt;/cli:body&gt; &lt;met:google-mail-signature xmlns:met="google:metadata"&gt;0c7ef6e618e9876b&lt;/met:google-mail- signature&gt; &lt;x stamp="20090309T14:20:05" xmlns="jabber:x:delay"/&gt; &lt;time ms="1236608405975" xmlns="google:timestamp"/&gt; &lt;/cli:message&gt; </code></pre> <p>When I try to build the XML tree like so:</p> <pre><code>root = etree.Element("cli:message") </code></pre> <p>I get this error:</p> <pre><code>Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; File "lxml.etree.pyx", line 2568, in lxml.etree.Element (src/lxml/lxml.etree.c:52878) File "apihelpers.pxi", line 126, in lxml.etree._makeElement (src/lxml/lxml.etree.c:11497) File "apihelpers.pxi", line 1542, in lxml.etree._tagValidOrRaise (src/lxml/lxml.etree.c:23956) ValueError: Invalid tag name u'cli:message' </code></pre> <p>When I try to escape it like so:</p> <pre><code>root = etree.Element("cli\:message") </code></pre> <p>I get the exact same error. </p> <p>The header of the chats also gives this information, which seems relevant:</p> <pre><code>Content-Type: text/xml; charset=utf-8 Content-Transfer-Encoding: 7bit </code></pre> <p>Does anyone know what's going on here?</p>

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.
