I am getting following error when trying to parse large DITA/DITAMAP files with
DTD validation enabled. Seems this is caused by xmlCtxtSetMaxAmplification
setting of libxml2 (https://github.com/GNOME/libxml2/blob/master/NEWS)
A new API function xmlCtxtSetMaxAmplification was added to allow parsing
of files that would otherwise trigger the billion laughs protection.
/**
* xmlTextReaderSetMaxAmplification:
* @reader: an XML reader
* @maxAmpl: maximum amplification factor
*
* Set the maximum amplification factor. See xmlCtxtSetMaxAmplification.
*/
void
xmlTextReaderSetMaxAmplification(xmlTextReaderPtr reader, unsigned maxAmpl)
{
if (reader == NULL)
return;
xmlCtxtSetMaxAmplification(reader->ctxt, maxAmpl);
}
Is it possible to avoid triggering the XMLSyntaxError in the LXML?
The parser I am usinbg is constructed as below:
dtd_xml_parser = et.XMLParser(dtd_validation=True, no_network=False,
huge_tree=True)
