    copied!<p>I'm trying to write a simple program to read my financial XML files from GNUCash, and learn Python in the process.</p> <p>The XML looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;gnc-v2 xmlns:gnc="http://www.gnucash.org/XML/gnc" xmlns:act="http://www.gnucash.org/XML/act" xmlns:book="http://www.gnucash.org/XML/book" {...} xmlns:vendor="http://www.gnucash.org/XML/vendor"&gt; &lt;gnc:count-data cd:type="book"&gt;1&lt;/gnc:count-data&gt; &lt;gnc:book version="2.0.0"&gt; &lt;book:id type="guid"&gt;91314601aa6afd17727c44657419974a&lt;/book:id&gt; &lt;gnc:count-data cd:type="account"&gt;80&lt;/gnc:count-data&gt; &lt;gnc:count-data cd:type="transaction"&gt;826&lt;/gnc:count-data&gt; &lt;gnc:count-data cd:type="budget"&gt;1&lt;/gnc:count-data&gt; &lt;gnc:commodity version="2.0.0"&gt; &lt;cmdty:space&gt;ISO4217&lt;/cmdty:space&gt; &lt;cmdty:id&gt;BRL&lt;/cmdty:id&gt; &lt;cmdty:get_quotes/&gt; &lt;cmdty:quote_source&gt;currency&lt;/cmdty:quote_source&gt; &lt;cmdty:quote_tz/&gt; &lt;/gnc:commodity&gt; </code></pre> <p>Right now, i'm able to iterate and get results using </p> <pre><code>import xml.etree.ElementTree as ET r = ET.parse("file.xml").findall('.//') </code></pre> <p>after manually cleaning the namespaces, but I'm looking for a solution that could either read the entries regardless of their namespaces OR remove the namespaces before parsing.</p> <p>Note that I'm a complete noob in python, and I've read: <a href="https://stackoverflow.com/questions/3378409/python-and-gnucash-extract-data-from-gnucash-files">Python and GnuCash: Extract data from GnuCash files</a>, <a href="https://stackoverflow.com/questions/2545783/cleaning-an-xml-file-in-python-before-parsing">Cleaning an XML file in Python before parsing</a> and <a href="https://stackoverflow.com/questions/1703882/python-xml-etree-elementtree-removing-namespaces">python: xml.etree.ElementTree, removing &quot;namespaces&quot;</a> along with ElementTree docs and I'm still lost...</p> <p>I've come up with this solution:</p> <pre><code>def strip_namespaces(self, tree): nspOpen = re.compile("&lt;\w*:", re.IGNORECASE) nspClose = re.compile("&lt;\/\w*:", re.IGNORECASE) for i in tree: start = re.sub(nspOpen, '&lt;', tree.tag) end = re.sub(nspOpen, '&lt;\/', tree.tag) # pprint(finaltree) return </code></pre> <p>But i'm failing to apply it. I can't seem to be able to retrieve the tag names as they appear on the file.</p>
