Question

I have the following Python code:

import xml.dom.minidom import xml.parsers.expat  try:     domTree = ml.dom.minidom.parse(myXMLFileName) except xml.parsers.expat.ExpatError, e:     return e.args[0] 

which I am using to parse an XML file. Although it quite happily spots simple XML errors like mismatched tags, it completely ignores the DTD specified at the top of the XML file:

<?xml version='1.0' encoding='UTF-8' standalone='no' ?> <!DOCTYPE ServerConfig SYSTEM 'ServerConfig.dtd'> 

so it doesn’t notice when mandatory elements are missing, for example. How can I switch on DTD checking?

See this question – the accepted answer is to use lxml validation.
