A simple example taken from the lxml site: from StringIO import StringIO from lxml import etree dtd = etree.DTD(StringIO(“””<!ELEMENT foo EMPTY>”””)) root = etree.XML(“<foo/>”) print(dtd.validate(root)) # True root = etree.XML(“<foo>bar</foo>”) print(dtd.validate(root)) # False print(dtd.error_log.filter_from_errors()) # <string>:1:0:ERROR:VALID:DTD_NOT_EMPTY: Element foo was declared EMPTY this … Read more
Validating a HUGE XML file
Instead of using a DOMParser, use a SAXParser. This reads from an input stream or reader so you can keep the XML on disk instead of loading it all into memory. SAXParserFactory factory = SAXParserFactory.newInstance(); factory.setValidating(true); factory.setNamespaceAware(true); SAXParser parser = factory.newSAXParser(); XMLReader reader = parser.getXMLReader(); reader.setErrorHandler(new SimpleErrorHandler()); reader.parse(new InputSource(new FileReader (“document.xml”)));
