<p style="color: grey"> Python recipe 578948 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/algorithm/">algorithm</a>, <a href="/recipes/tags/algorithms/">algorithms</a>, <a href="/recipes/tags/flatten/">flatten</a>, <a href="/recipes/tags/list/">list</a>, <a href="/recipes/tags/lists/">lists</a>, <a href="/recipes/tags/python/">python</a>). </p> <p>This is a recipe to flatten a Python list which may have nested lists as items within it. It works for lists that have a maximum depth of nesting roughly equal to the recursion depth limit of Python, which is set to 1000 by default, though it can be increased with sys.setrecursionlimit().</p>

It transforms a XML file into a flat text output, with <em>XPath</em>-like syntax, one line per XML node or attribute. This format is more suitable for working with standard unix CLI utils (sed, grep, ... etc).</p>
