    <p>I have several large .xml files. I want to parse out the files to do several things. </p> <p>I want to pull out only:</p> <ul> <li>XML-/title1 and save it to list A (for example)</li> <li>XML-/title2 and save it to list B</li> <li>XML-/title3 and save it to list C</li> <li>etc, etc </li> </ul> <p>Using Python 2.x which library would be best to import/use. How would I set this up? Any Suggestions?</p> <p>For Example:</p> <pre><code> &lt;PubmedArticle&gt; &lt;MedlineCitation Owner="NLM" Status="MEDLINE"&gt; &lt;PMID Version="1"&gt;8981971&lt;/PMID&gt; &lt;Article PubModel="Print"&gt; &lt;Journal&gt; &lt;ISSN IssnType="Print"&gt;0002-9297&lt;/ISSN&gt; &lt;JournalIssue CitedMedium="Print"&gt; &lt;Volume&gt;60&lt;/Volume&gt; &lt;Issue&gt;1&lt;/Issue&gt; &lt;PubDate&gt; &lt;Year&gt;1997&lt;/Year&gt; &lt;Month&gt;Jan&lt;/Month&gt; &lt;/PubDate&gt; &lt;/JournalIssue&gt; &lt;Title&gt;American journal of human genetics&lt;/Title&gt; &lt;ISOAbbreviation&gt;Am.

    1. COI'd use `xml.dom.minidom` for this, it comes with Python and works fine. `lxml` is another good library but you'd have to install it.

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.
